## Yasuko Rivers (née Rivera)

**Yasuko Annabel Cascade Rivers** (née **Rivera**) (b.18 January, 1973) was an English pure-blood witch; the younger child of Jasper and Kya Rivera and the younger sister of Jacob Rivera. She was a Hufflepuff student who attended Hogwarts from 1984-1991, where she met Erica Rivers. After graduating from Hogwarts, Yasuko married Erica and gave birth to a child, Lapis Sierra Rivers.

During her final year at Hogwarts, Yasuko served as a confidant and comforter for Nathara and Aurora. She was kind, passionate, gentle, brave, smart, and understanding, attributes that made her popular among the student body.

Seven years after she left school, Yasuko and her wife fought in the Battle of Hogwarts and survived, with Yasuko later giving birth to another daughter sometime in the early 2000s, Moana Rivers, and a son, Matthew Rivers. Through her eldest daughter's marriage to Zuko Hunter, Yasuko had three grandchildren; Maria, Kallik, and Calypso.

## Early life

Yasuko was born on the 18th of January in 1973 to Jasper and Kya Rivera and had one older sibling, a brother named Jacob. She lived in close proximity to Muggle dwellings, but she showed little knowledge of Muggle life as an adolescent and had limited interaction with her neighbors. Growing up, Yasuko and Jacob were the best of friends and were almost never separated.

When she was five or six years old, she and Jacob pretended to duel with Liquorice Wands. At one point, Jacob convinced his sister to steal Sickles from her mother's coat pockets.

During her childhood, her parents worked together to teach Jacob and Yasuko that she could not go around flaunting her magic. In particular, her mother was strict about the use of magic outside of school, refusing both of her children to ride a broomstick before she began attending school.

She performed wandless magic when she was young, shattering one of her mother's tea sets when She sneezed. her mother thought Jacob had done it until She repeated the feat with a vase a few weeks later when Jacob was at school. On another occasion, she laughed a flower back to life which her mother was pretty pleased with.

Jacob began attending Hogwarts during her childhood. Tragedy struck the family when she received an owl from Professor Albus Dumbledore, informing them that Jacob had been expelled for endangering his fellow students in his attempt to prove that the fabled Cursed Vaults really existed.

Shortly after being sent home, Jacob ran away and went missing; many believed that he went on to serve Lord Voldemort, whereas other rumours said he had returned to Hogwarts after his expulsion to resume his search. His younger sister would, years later, reject the former possibility. When his sister and mother heard he went missing, she was upset over the news and cried.

## Hogwarts years (1984–1991)

#### First year

##### Sorting Ceremony

"*Hmm… very interesting. I haven't seen one like this in a long time.*"
— The Sorting Hat whilst sorting Yasuko
On 1 September 1984, Yasuko boarded the Hogwarts Express on Platform Nine and Three-Quarters, through the magical barrier at King's Cross Station. Upon arrival, she was greeted at the Great Hall by the rest of the students and the staff. Professor McGonagall proceeded to provide them with a short explanation of the four Hogwarts Houses, voicing her hope that all of the newcomers would make fine additions to the ranks of great witches and wizards that each House had produced in the past. When Yasuko was called to be Sorted, the Sorting Hat remarked that "[it hadn't] *seen one like this in a long time*", and took her choice of House into account — which was the same as her brother Jacob's. Later, she found that Rowan had been Sorted into the same House as them.

When the sorting was done and all first-years had found places to sit among their new housemates, Professor Dumbledore rose and stood behind the Owl Lecturn in front of the High Table. He gave a brief speech of welcomes, educated the new arrivals on the rules of the House Cup and on what a great honour it would be to win it. At the end of the Start-of-Term Feast, Yasuko's Head of House moved to stand beside the Headmaster, announcing to the students of their house that it was time for them to move to their common room. Once there, Yasuko reunited with Rowan, and the two briefly discussed their shared excitement over finally attending school and their new House before agreeing to go to bed, as they would have to be up bright and early for Charms first thing in the morning.

##### Charms class

**Yasuko**: "*Pleased to meet you, Professor Flitwick. I'm really looking forward to Charms.*"
**Filius Flitwick**: "*You're Miss Rivera! If you're anything like your brother, you will do just fine. He was one of my most skilled students. That being said, he was also one of my most rebellious students...*"
— Yasuko meeting Professor Flitwick
As Charms was one of the subjects Yasuko had most looked forward to, when arriving at the Charms Classroom, she courteously greeted the Charms Master, Professor Flitwick. Recognising the individual as Yasuko, Filius Flitwick answered in kind words, claiming that he was certain she would do just fine, as her older brother had been one of his most skilled students at Hogwarts prior to his expulsion. Even so, he subtly warned them against trouble-making, adding that Jacob had been one of his most rebellious students as well. For the student's first class, they studied the Wand-Lighting Charm.

##### Meeting Merula Snyde

"*Merula Snyde. First-year Slytherin. The best witch at Hogwarts. I overheard the professors whispering about you at the Feast. I suppose you think you're better than me. I should put you out of your misery before you ruin Hogwarts like your brother tried to.*"
— Merula Snyde taunting Yasuko
Later on, Yasuko encountered Merula Snyde, an imperious and cruel Slytherin student, who tried to bully Rowan into admitting her as the most powerful witch to ever attend Hogwarts. Yasuko intervened on Rowan's behalf and stood up for her against Merula, but before their argument went any further, Professor Prince-Slytherin ordered them to get into the Potions Classroom for the subsequent class. The animosity formed between Merula and Yasuko grew in that lesson, for at the end of the class, Merula sabotaged the Cure for Boils Yasuko brewed with Bulbadox powder, which caused the potion to explode, resulting in them losing ten points for their house due to their presumed clumsiness.

##### Merula's prank

**Yasuko**: "*What is that thing?!*"
**Merula Snyde**: "*A deadly plant called Devil's Snare. Some fourth-year Slytherins showed it to me when I first arrived. It's sensitive to light. If you're really better at the Wand-Lighting Charm than me, escaping should be no problem.*"
**Yasuko**: "*Merula?! You locked us in here?!*"
**Merula Snyde**: "*Along with sending you a fake letter from Prince-Slytherin. I told you things would only get worse for you, Rivera.*"
— Yasuko (in the room with the Devil's Snare) talking to Merula (outside the room)
Not long after the incident, Yasuko was introduced to Ben Copper and the House Prefect. The Prefect gave Yasuko a note from Professor Prince-Slytherin stating he would consider restoring the points if they fetched some Pickled Slugs from a storage room. Yasuko found the room following instructions on the note, but the room turned out to be filled with Devil's Snare, which quickly tied Yasuko up. Merula appeared outside the room and revealed she had forged the note. Fortunately, Rubeus Hagrid arrived in time and saved her.

##### Learning to duel

**Prefect**: "*I'm going to teach you two how to duel.*"
**Yasuko**: "*But we don't know any duelling spells…*"
**Prefect**: "*Hufflepuff keeps a secret duelling book hidden in the Artefact Room. It will teach you various spells, potions, and techniques. Meet me again after you've learned a duelling spell, and I'll teach you everything else you need to know.*"
— Yasuko's Prefect deciding to teach them how to duel
Yasuko's Prefect decided to teach them how to duel after Merula hit them with Flipendo. They went to the Artefact Room with Rowan to get a duelling book, but saw some visions in their head and heard a mysterious voice saying a kind of ice was here and a vault would open. Nevertheless, they acquired the book. They learned the Disarming Charm from Professor Flitwick and another spell with Rowan.

## Post-Hogwarts

#### Marriage and motherhood

After graduating from Hogwarts, Yasuko married her girlfriend, Erica Rivers in the summer of 1991. After a year of marriage, Yasuko got pregnant with the couple's child in the late summer/early autumn of 1992. In the first few months of her pregnancy, Yasuko kept in correspondence with her friends, Aurora Pikeman and Nathara Prince-Slytherin. She thought of the two girls as her younger sisters, since she was the baby in her family, and wanted them to be involved in her baby's life.

Eventually, in the winter of 1993, Yasuko gave birth to a daughter, Lapis Sierra Rivers. When her daughter was a month old, Yasuko and Erica took her to Hogsmeade to meet Aurora and Nathara for the first time.

She and her wife fought in the Battle of Hogwarts, leaving their daughter in the care of Yasuko's parents. Following the war, Yasuko gave birth to two more children, a daughter, Moana, and a son.

## Later life (1998-?)

Surviving the Battle of Hogwarts, Yasuko expanded her family. She got pregnant again and gave birth to another daughter, Moana, with a son joining them three years later. She kept in close contact with her friends, while remembering Rowan, and grew close with their children, to the point that they started calling her "Auntie Suki". Yasuko and her wife opened the Rowan Memorial Daycare Center, where she worked as a caretaker for the children.

In honor of her deceased friend, Yasuko doubled the daycare center as an orphanage to help magical children in dangerous situations. All of the children that attend the daycare adored her and treated her like she was their mother. Her own children started helping out once they were old enough, and eventually, Aurora and Nathara sent their own children to the daycare to prepare them for Hogwarts.

Her old professor, Severus, sent his youngest three, Alan, Kya, and Aisha, to the daycare as well; showing how much he has grown to trust her. All he told her was "*I saw how good you were with the children, Mrs. Rivers. I hope you're able to teach* my *children the same way,*"

However, when her old rival Merula Snyde threatened to tear down the daycare, Yasuko and her family and friends pleaded with her to change her mind and let go of her bitterness. Eventually, Merula and Yasuko managed to overcome their animosity towards each other and became friends and friendly rivals, with the promise to have a friendly duel someday.

## Physical description

Yasuko was a beautiful woman with thick, dark brown hair that fell to her waist, and almond-shaped, bright blue eyes. Apparently, her eyes are extremely distinctive, because every person who knows Yasuko would always see them in her children and granddaughter, Lapis, Moana, Matthew, and Maria.

She was of average height for her age and had an hourglass figure in her late teenage years. It was baffling to some of her peers how such a shy and small girl could blossom into such a beautiful swan as an adult, but Yasuko did.

Out of all her features, Yasuko's smile was considered the most beautiful, and after inheriting her mother's betrothal necklace, it enhanced her beauty all the more.

Like the late Liliana "Lily" Potter, Yasuko had something special about her that just attracted someone's attention.

## Personality and traits

Yasuko was extremely compassionate and, while not as perceptive as her best friend Rowan Khanna, still possessed a keen intellect. She was very talented and academically competent, as well as popular in her later years, being skilled in a number of magical fields, receiving much praise from the majority of their teachers, often responding to such praise by grinning or smiling fondly. She was also skilled at coming up with things quickly and lying effectively, though she never lied if she could avoid doing so.

Thanks to the actions of her brother Jacob, she was often the subject of dislike and apprehension and had difficulty making friends. She was unfazed by this, and instead chose to be nonjudgmental and accepting of those around her. Yasuko was very loyal to her friends and treated them like siblings. She was always eager to help them, such as when she helped Ben Copper overcome his fear of riding a broomstick and convinced him to stop isolating in a closet, and when she acted like they could see through Talbott Winger's apparent lack of desire for friendship in general. Yasuko was also very empathetic, as best shown by how she treated Talbott Winger, Barnaby Lee, Ismelda Murk and Merula Snyde.

Yasuko was very courageous, as she stood up to Merula Snyde, Albus Dumbledore, and even Fenrir Greyback, and sought out the Cursed Vaults relentlessly in spite of the teachers warning her not to. Yasuko believed that in finding the vaults, she would gain new knowledge and treasure, but most of their drive came from wanting to find she brother, whom she loved and missed unconditionally.

Though never a defining trait, Yasuko had a cheeky and occasionally sarcastic sense of humour, such as when she encouraged Ben to stop isolating and added "*…though the skulls might miss you*". In her first year, Merula told her she was unwanted to which she replied "*You're the one everyone wishes would just go away.*" When Chiara Lobosca accused her of having ulterior motives for chatting, she replied, "*It's possible my ulterior motive might be trying to get to know you better.*"

In her second year, Yasuko developed a passion for Quidditch as well as possessing a natural talent for it, which created a bond with Skye Parkin and, later, Erika Rath. She initially started as a Chaser, though in subsequent years, opening in the team roster also saw her playing Beater, Keeper, and Seeker. In her fourth year, team captain Orion Amari stepped back from duties while recovering from an injury, so Yasuko and Skye split the captain's role between them.

For Yasuko, her years at Hogwarts had been a journey of growth and renewal. Despite being a lonely child who frequently watched her brother closely with immense concern and kept to herself, Yasuko had found a family at school that could relate to her and give her new purpose and meaning. Her social skills improved phenomenally during her magical education. Indeed, she tended to form the closest relationships (positive and negative) with students who brought out her own strengths: being around Rowan Khanna had made her more intellectual, being around Ben Copper had made her more compassionate, being around Penny Haywood had made her more extroverted, being around Willow Tonks had made her more unafraid of being herself, being around Skye Parkin had made her more sports-minded, and being around Merula Snyde had made her more empathetic and less vulnerable. Yasuko tended to have some of those effects on her friends in turn, as people like Haywood and Talbott Winger had pointed out, she was both a safe place and dependable source when her friends were vulnerable, endangered, conflicted, or all of the above.

## Magical abilities and skills

"*Father says you are the best in your year.*"
— Draco Malfoy
* **Magical aptitude**: An academically strong student, Yasuko quickly achieved such good results in her schoolwork that she received praise from most of her teachers, with Albus Dumbledore, arguably the greatest wizard of all time, openly acknowledging her magical prowess to be exemplary. she demonstrated tremendous ability and proved a cleverer student than most of her classmates, quickly mastering and becoming the best in most of the fields of magic taught at Hogwarts. Indeed, her formidable magical power allowed them to achieve O.W.L.s in all her subjects, to apprehend the immensely savage Fenrir Greyback alongside the Werewolf Capture Unit, to assist Auror Alastor Moody in tracking down the malevolent organisation R, to come out as the triumphant winner of the prestigious All-Wizard Tournament, to master the extremely powerful and difficult Patronus Charm by only her fourth year, and to save Hogwarts from the menacing threat of the Cursed Vaults on numerous occasions.
* **Love**: Yasuko loved her older brother unconditionally, being devastated when he went missing from home and shedding tears over his sudden disappearance. her love for him spurred them to take action and rescue him by obsessively searching for the Cursed Vaults for many years, despite her teachers explicitly forbidding them to do so under the threat of expulsion from Hogwarts and despite the extreme danger in which Yasuko repeatedly placed themselves under while seeking out each of the Cursed Vaults. Although her love was at its strongest when directed towards her brother, as he was the driving force that kept them persisting until she found him, her love also extended towards her friends, whom she were always willing to help or assist in whatever way she could whenever her friends were vulnerable, endangered or conflicted, which, in turn, resulted in Yasuko developing an exceedingly compassionate nature. her compassion even enabled them to sympathise with those whom she were initially antagonistic with, such as Merula Snyde, Barnaby Lee, and Ismelda Murk.

"*You truly do have a gift for Charms.*"
— Filius Flitwick

* **Charms**: Yasuko was known to be exceptionally skilled in charm-work, as she achieved either an "Exceeds Expectations" or "Outstanding" on her O.W.L. exam to be able to advance to N.E.W.T.-level Charms. In her very first lesson, she cast the best Wand-Lighting Charm that Professor Flitwick had seen from a first-year in a long time. she were usually the first to master any new spell Professor Flitwick taught (such as the Disarming Charm, the Levitation Charm, and the Unlocking Charm) with little difficulty, and by her second year, she were capable of casting the Shrinking Charm to such an effect that she became the size of an insect and thus, virtually invisible to the naked eye. she could also just as easily reverse the effect with an Engorgement Charm without experiencing any side effects. During class, Professor Flitwick would often commend them for her 'fine technique' and even request that she assist him in demonstrating how to cast spells properly for her fellow classmates, as well as tutouring classmates in various spells. By her fourth year, she produced a Shield Charm that was strong enough to deflect a Blasting Curse from the much older and more experienced Patricia Rakepick, visibly impressing her. she even performed an advanced Memory Charm to erase the memory of Merula Snyde when she overhead important information about Talbott Winger in her third year. Yasuko was also able to cast a Levitation Charm so powerful that it made themself levitate mid-air during her fourth year. Furthermore, she learned how to conjure a fully-corporeal Patronus Charm by her fourth year, an outstanding feat for a Hogwarts student. Indeed, the Charms Master himself openly acknowledged Yasuko to be one of his most talented students. Outside of class she notably tutored Skye Parkin, in return for her training in Quidditch techniques while planning to try out for her House Quidditch team .

"*You continue to exhibit a gift for Potions.*"
— Severus Prince-Slytherin

* **Potions**: Yasuko was superbly talented in potion-making, as she achieved an "Outstanding" on her O.W.L. exam to be able to advance to the N.E.W.T.-level Potions class taught by Severus Snape, thus displaying her great proficiency for potion-making. she were able to brew everything from basic to moderately difficult concoctions to the desired effect, notably brewing a Fire-Breathing Potion flawlessly after only seeing the Potions Master do it once. Indeed, despite his personal dislike of the student, Severus Prince-Slytherin himself admitted that this individual had an undeniable gift for potions and Penny Haywood, arguably the best student of the subject, praised Yasuko's talent in potion-making, going so far as to suggest that she consider a career as a Potioneer.

* **Duelling**: Yasuko quickly became a formidable duellist for her age, outclassing the likes of the more experienced Merula Snyde and even Bill Weasley, both of whom were of one of the most skilled students at Hogwarts, with the latter having two years of education over them. Though usually coming out triumphant in most duels against her peers, she eres unable to beat Ben Copper in a duel to the death, who trounced them but was quickly defeated when Patricia Rakepick came for the rescue, striking him with a Blasting Curse. This individual's skills were already so great by her first year that she could even hold off Fenrir Greyback while he was in his werewolf form, with some swift spell-casting. By her fifth year, she were able to out-duel a Dark Witch in Knockturn Alley, despite being there for the first time and defeated an adult wizard named Alistair Fidgen, when he threatened her friend Jae Kim. However, she were no match for Patricia Rakepick, as she easily subdued them before she could even cast a spell in her fifth year and again when she attempted to attack her in her sixth year. she also acknowledged the vast gap between them and Dumbledore, noting that it would be suicide for them to try to infiltrate his office. This individual was able to out-duel the more experienced Peter Pettigrew after he revealed himself to them. her duelling aptitude was also clearly staggering in that she were capable of facing and subduing some of the most dangerous beasts in the world, notably being capable enough to overpower the Forest Vault Acromantula (with even the formidable Rubeus Hagrid being seemingly unwilling to contend with the beast), to single-handedly defeat a Hungarian Horntail (with even the incredibly powerful Patricia Rakepick being incapable of performing such a feat during her youth, despite having received assistance from accomplices) and to hold off the incredibly savage Chimaera long enough for others to come to her rescue on more than one occasion. By her sixth year, she were even able to contend with Alastor Moody, who was considered to be the most famous Auror of all time and an extremely skilled duellist, in a duel training with him. Although she themselves acknowledged that Moody wasn't fighting seriously, which Moody himself admitted as he was only trying to assess her skills, Moody still acknowledged her duelling prowess, even going so far as to say that she could give some of his Aurors difficulty in besting them. her duelling skills improved considerably by the time she ventured into the Sunken Vault, as she managed to single handedly defeat the extremely talented and dangerous Patricia Rakepick with a powerful Disarming Charm after she defeated Merula Snyde, Ben Copper and Jacob, and surprised, acknowledged that her skills improved since the last time she met. By her seventh year, this individual received Auror field training in the Ministry of Magic under Alastor Moody's supervision, which helped further improve her duelling skills. she were able to defeat Zenith Xeep in a duel in Knockturn Alley, forcing her to drink her own Luscious Locks Solution, which erased her entire memory, in order to avoid getting captured and giving them information about the stolen wand and the Dark Witch she was talking to. her ability to fight both skilled duellists and dark wizards showed them to have considerable proficiency in martial magic.

"*You were born to fly.*"
— Rolanda Hooch

"*You're a Quidditch phenom.*"
— Murphy McNully

* **Flying**: Yasuko's flying skills were exceptional, beyond the array of aerial manoeuvres taught in Flying class. she was also a very skilled Quidditch player, joining her house's team as Chaser initially in her second year. Showing natural courage, instincts, agility and stamina, she convinced Skye Parkin to coach them. Some of her most impressive feats on a broomstick range from balancing one-legged on a broom for nearly three hours, to weaving through three opposing Chasers while broom-surfing with incredible reflexes and dexterity. She even managed to do a triple back flip while at 400 ft above the ground.
* **Quidditch knowledge**: Yasuko confessed to Andre Egwu that she was knowledgeable in Quidditch, despite not playing the sport themselves until second year, during which she gained more knowledge with help from Penny Haywood, and possibly even passed the Face Paint Kid's Knowledge Quiz.

"*Your skill in Transfiguration belies your years.*"
— Minerva McGonagall

* **Transfiguration**: Yasuko demonstrated considerable talent in transfiguration, as she achieved either an "Exceeds Expectations" or "Outstanding" on her O.W.L. exam to be able to study the subject further at N.E.W.T.-level. she succeeded in casting the best Reparifarge spell (an untransfiguration spell) on her first try, impressing even Professor Minerva McGonagall with her talent, who deemed her abilities in transfiguration to belay her years. As a matter of fact, McGonagall was so impressed that she even offered to give this individual advanced transfiguration lessons outside the class. Yasuko was also able to learn the intermediate level Revelio Charm (normally taught to fourth-year students) by her second year. Indeed, her skill in this subject was so advanced that already before graduating, she were able to become a fully-fledged Animagus, with immense dedication and hard work.
* **Herbology**: By her own admission, one of Yasuko's favourite classes was Herbology, with them being able to achieve an O.W.L. on the subject and study it further at N.E.W.T.-level, thus demonstrating her proficieny for the magical field. she were knowledgeable in various types of magical plants and were also able to successfully grow a perfect specimen of Sugar Shrub in her third year, remarking that whoever drank Butterbeer made with this was in for a "sugar shock", thus showcasing her impressive talent in this subject.

"*You have a way with patients.*"
— Poppy Pomfrey

* **Healing magic**: After taking care of an injured Rowan, Yasuko became an assistant of Madam Pomfrey, and studied healing magic on her own, who would eventually denote them as a natural Healer and an exceptional assistant, to the point of beginning to wonder if Yasuko might eventually proceed her in being responsible for the Hospital Wing one day, which certainly highlighted her skill and knowledge in medical magic. she was proficient with the casting of the Healing spell *Episkey* as well as the Bandaging Charm.

"*Yeh got a way with creatures.*"
— Rubeus Hagrid

* **Care of Magical Creatures**: Yasuko was shown to possess a natural flair for Care of Magical Creatures, being able to achieve an O.W.L. on the subject and study it further at N.E.W.T.-level, thus showcasing her talent for handling and communicating with various magical creatures, along with the understanding of them. This individual began taking this class in her third year of Hogwarts education, and was known to have been rather good in the subject, showing her interest and skill in the field of Magizoology. Indeed, Charlie Weasley, one of the best students of the subject, commended Yasuko's flair for tending to magical creatures, going so far as to suggest that she consider a career as a Magizoologist.
* **History of Magic**: Yasuko was skilled in History of Magic, as she were able to achieve an O.W.L. in the subject and study it further at N.E.W.T.-level., an impressive achievement, given the subject's infamy for being exceedingly dull. Ismelda Murk, one of the best students of the subject, recognised Yasuko's knowledge in magical history, going so far as to suggest that she consider a career as a Magical Historian.
* **Defence Against the Dark Arts**: When she were tutored, alongside the rest of her year, by the famous Patricia Rakepick, in Defence Against the Dark Arts, Yasuko soon became the best student of the subject, seamlessly mastering Hex Deflection and proving quite adept in repelling the dark creatures of the lessons. Rakepick herself praised her abilities in this field, with them having achieved either an 'Exceeds Expectations or 'Outstanding' on her O.W.L. exam to be able to study the subject further at N.E.W.T.-level. she also successfully learned many defensive and offensive spells during her DADA education, including spells taught by her classmates. For an example of her defensive skills, in her Third year, she were successfully able to subdue a Boggart in the form of Lord Voldemort with the Boggart-Banishing Spell. Indeed, Alastor Moody, arguably the greatest Auror of all time, expressed his pride in Yasuko, praising them for her Auror-like mindset while Willow Tonks, who would later grow up to become a successful Auror, suggested that Yasuko consider the career, given that she had experience hunting down Dark wizards and clearly displayed familiarity with the job and training.
* **Dark Arts**: Though seldom a practitioner of the Dark Arts, Yasuko was nonetheless surprisingly adept in its usage, being able to successfully cast a vast array of dark charms, such as the hex *Densaugeo*, the Sea Urchin Jinx, the Knockback Jinx, *Langlock*, the Curse of the Bogies, the Ear-Shrivelling Curse, the Jelly-Legs Curse, the Conjunctivitis Curse, the Reductor Curse and the Blasting Curse. she were, however, horrified when Patricia Rakepick used the Cruciatus Curse on a Dark Wizard in Knockturn Alley, rejecting her offer to teach the curse to them and adamantly refusing to ever use it on anyone.
* **Nonverbal and Wandless**: Yasuko was apparently quite capable in casting nonverbal spells, as she subdued a Hungarian Horntail using the Sleeping Charm, duelled against Patricia Rakepick in the Portrait Vault and later again in the Forest Grove, all without uttering a word. she also demonstrated impressive wandless magic when using the Butterfly-conjuring spell during her imitation of the Beauxbatons dance routine, a performance that Madame Maxime ultimately deemed magnificent. she performed wandless magic when she were young, shattering one of her mother's tea sets when she sneezed. her mother thought Jacob had done it until she repeated the feat with a vase a few weeks later when Jacob was at school. On another occasion, she laughed a flower back to life.
* **Legilimency**: This individual was a natural-born and powerful Legilimens, like her brother Jacob, thus giving them the magical ability to read and navigate the minds of others. she have successfully used this power against Argus Filch, Madam Rosmerta, and several of the Hogwarts house-elves, but were repelled by Severus. she also lacked any facility with Occlumency and were thus unable to defend themselves from mental intrusion.
* **Spell creation**: Yasuko helped Badeea Ali invent the Star Shower Spell and designed the Snowfall spell to such potency by themselves that she inadvertently created a snowstorm. Nonetheless, these are both highly impressive magical achievements, given the very high level of difficulty of creating new spells.
* **Curse-Breaker**: Like Bill Weasley, this individual was a gifted curse-breaker, even when it was due to the urgency to find Jacob. This individual was able to unlock the secrets behind the Cursed Vaults.
* **Divination**: Yasuko was skilled in Divination, as she were able to achieve an O.W.L in the subject and study it further at N.E.W.T.-level, thus showing aptitude in the subject.
* **Astronomy**: Yasuko was skilled in Astronomy, as she were able to achieve an O.W.L in the subject and study it further at N.E.W.T.-level, thus showing aptitude in the subject.
* **Muggle Studies**: Yasuko was skilled in Muggle Studies, as she were able to achieve an O.W.L in the subject and study it further at N.E.W.T.-level, thus showing aptitude in the subject.
* **Singing skills**: Yasuko was a surprisingly skilled singer, as when singing with Tulip Karasu's toad Dennis in front of a variety of listeners, her skills were sufficient enough to be acknowledged by the popular music band the Weird Sisters, Choir Master Filius Flitwick and even Severus Prince-Slytherin. Indeed, despite the relatively short time that she had to begin honing her singing capabilities, she already proved themselves to surpass the singing prowess of the more experienced Merula Snyde. As such, Yasuko put on such an impressive showing to Flitwick during her audition to be the newest member of the Frog Choir, that Tulip deemed her performance to be the best out of all the participants, which was ultimately proven true when Flitwick offered them exclusive membership into the Frog Choir. She used her singing talent to calm Aurora down when she needed some comefort.
* **Dancing skills**: Yasuko had some skills in dancing, as she learned the Badger Shuffle and used it to win the Team Dance Contest with Diego Caplan. she also participated in several balls organised by the school, such as the Celestial Ball and the Valentine's Day Ball.

"*You have a talent for solving mysteries.*"
— Albus Dumbledore

* **Detective skills**: Yasuko had tremendous skills in tracking and detection, since she tracked down her brother Jacob to the Portrait Vault after years of skilfully employing both inductive and deductive reasoning in her dogged pursuit of the Cursed Vaults, outsmarting the Aurors and the professors that had investigated the Vaults prior to Yasuko's arrival at Hogwarts.
* **Teaching skills**: Yasuko was an excellent teacher of Charms, as she often tutored struggling students. This was even acknowledged by Professor Flitwick and Professor Tofty.
* **Leadership skills**: Yasuko was shown to be a very accomplished and talented leader, as she were able to found and effectively lead the Circle of Khanna against R, productively coordinating the group's efforts and inspiring fierce loyalty from them all.
* **Willpower**: The will of Yasuko was extremely strong, and while not above self-doubt, she have never been known to give up on anything or anyone, tirelessly seeking the Cursed Vaults for the sake of her brother. her willpower gave them great courage, enough to stand in the face of Merula's antics, Snape's cruelty, and Greyback's murderous intent.
* **Artistic skills**: Yasuko had some artistic skills, as she helped Badeea Ali paint for the Valentine's Day Ball.
* **Cooking skills**: Yasuko had some cooking skills, as she proved to be capable of making food that even pleased Madam Pince and Professor Snape.
* **Wizard's Chess**: Yasuko had some talent in Wizard's Chess, as she even impressed Professor McGonagall with her ability.
* **Charisma**: Yasuko was highly talented in befriending and inspiring others, such that she were able to quickly form many strong friendships and even befriend people that were hostile towards them.
* **Alchemy**: During investigations about a rogue alchemist, Yasuko studied books about Alchemy, and was able to successfully apply her newly gained knowledge about the subject.

### Family

**Jacob**: "*Thank you for not giving up on me.*"
**Yasuko**: "*I could have never given up on you. You're my older brother, and my best friend.*"
— Jacob and his younger sister, after reuniting.
    Jacob was Yasuko's older brother. She had a rather close and affectionate relationship with him during her early childhood, as she pretended to duel with Liquorice Wands with Jacob when she was younger and even stole Sickles from her mother's coat pockets at his behest. When Jacob came home after his first year of Hogwarts, he tried to teach her all the magic he learned at Hogwarts, of which she was unable to perform any of it, but it remained one of the three possibilities of her happiest memory used to cast the Patronus Charm. After Jacob went mysteriously missing following his expulsion from Hogwarts, his younger sister was left devastated and mourned his disappearance with her mother. When assaulted by a Dementor, she was forced to relive her worst memory: her mother sobbing uncontrollably upon learning Jacob's disappearance.

Jacob's disappearance also had major repercussions on his sister outside of family tragedy. Due to his morbid obsession with the Cursed Vaults, subsequent expulsion and apparent initiation into the Death Eaters, Jacob inadvertently established a rather infamous reputation and was perceived as insane by the wizarding world. Being of his kin, his younger sister, too, was largely viewed by suspicion, distrust and even hate (with Dumbledore, in secret, and Merula being among their biggest detractors), which thus affected her early years of schooling and ability to make a first good impression on people. Despite all this, however, Yasuko never felt bitter or resentful towards the negative publicity that she received, caused by her brother, and continued to feel nothing but unconditional love for Jacob. Her early years at Hogwarts was marked by agony over the mysterious whereabouts of her brother, thus leading her to resolve to find and rescue him no matter what.

Indeed, this strong, unconditional love for her brother became her primary point of obsession with seeking the Cursed Vaults, inciting her to sometimes behave recklessly and enact dangerous schemes in her goal to save Jacob, such as igniting the cloak of a member of faculty and fighting a troll in the Hogwarts grounds. She would also defend Jacob's honour against accusations and mockery when necessary, refusing to believe the perpetuated rumour that he was insane and had joined the Death Eaters.

After finally rescuing and reuniting her brother in 1989, Yasuko was shown to be incredibly relieved and happy at seeing her brother safe and sound.

#### Erica Rivers

Yasuko loved Erica with all of her heart, as much as she loved Jacob, and wanted her to know it.

### The Weasleys

#### Bill Weasley

Yasuko admired Bill Weasley, but not as much as Rowan Khanna did. The two became close allies because of how much they had in common and were both very helpful to each other when it came to martial magic.

#### Charlie Weasley

Yasuko better familiarized herself with Charlie Weasley in her third year of Hogwarts, during which she shared Care of Magical Creatures with him. Her friendship with him evolved to such that Charlie offered to talk down the imperious Merula Snyde on her behalf during their fourth year.

### Friends

#### Rowan Khanna

**Yasuko**: "*Well, Rowan, I guess it's time to say goodbye...*"
**Rowan Khanna**: "*Yes, Suko. We'll see each other again; when it's time for you to cross over. I'll be waiting for you until then.*"
**Yasuko**: "*Goodbye, Rowan....*"
**Rowan Khanna**: "*Goodbye, Yasuko.*"
— Yasuko saying goodbye to Rowan's spirit

Yasuko met Rowan Khanna at Diagon Alley. The two became best friends at school. They both bonded over the fact that both of them did not truly have anyone else going into Hogwarts — Yasuko was regarded as insane thanks to her brother's actions, and Rowan was socially inept and mostly talked about trees. They continuously helped each other get through both everyday and life-threatening situations. When Rowan died, she was devastated, and it was hard for her to get over the loss, as she thought of Rowan like a sister in everything but blood. She had other friends, but things were never the same without Rowan around. To make sure her friend and her memory weren't forgotten, Yasuko created and founded the Rowan Memorial Daycare & Orphanage, named in honor of Rowan's sacrifice and carried a picture of the two of them in a locket.

#### Ben Copper

Yasuko was quite friendly with Ben Copper, although not as close as Rowan. She cared deeply for his well-being, as she became very worried when he went missing, and showed her loyalty to him by infiltrating Gryffindor Tower merely because it may or may not lead to him. She also helped Ben to get over his fear of flying.

#### Penny Haywood

**Penny Haywood**: "*Thank you again for all of your help. I can't imagine what life would be like without you.*"
**Yasuko**: "*I feel the same way, Penny. I'll always be here for you. That's why I want to get to know everyone.*"
— Penny Haywood and Yasuko
Yasuko admired Penny Haywood for her popularity, kindness, and overall competence. She treated her cordially, but she got her attention by standing up to Merula Snyde. They brewed a potion together to neutralize Mrs Norris. Penny was grateful for Yasuko putting her in a life-threatening situation, as she loved excitement more than she did. She always seemed to know what was going on at Hogwarts, which made her very useful as well. She was surprised when she was close to Talbott Winger.
#### Willow Tonks

Yasuko and Willow Tonks met in their first year at Hogwarts, and shared Herbology class together. Over the course of the next couple of years, they grew close and became best friends, often going to Hogsmeade to visit Zonko's Joke Shop in particular in order to plan their pranks together.

#### Barnaby Lee

Yasuko initially had an antagonistic relationship with Barnaby Lee because of his loyalty to Merula and his threats to her. However, they began getting along better when Barnaby joined her side and Merula later did the same, and when she helped him when Ismelda Murk tried to drug him via Love Potion. He also said Yasuko was very polite and brave and looked adorable when she rolled her eyes in response to his puns and when she discussed animals and ruefully used Engorgement Charms on his drinks at Hogsmeade, though he was under magical effects when he said it.

#### Talbott Winger

"*I never thought I'd be happy to meet someone who can never mind their own business.*"
— Talbott Winger
Yasuko first met Talbott Winger when looking to become an Animagus. She was surprised to learn he was close to Penny Haywood. They did not, however, become friends until they located Talbott's swan necklace and took it back from Mrs Norris.
#### Andre Egwu

Andre Egwu attended Transfiguration and Flying classes with Yasuko, although the two didn't know each other a lot and only regarded the other as a classmate. When Yasuko ventured out to Hogsmeade for the first time, Andre properly introduced himself to them and expressed his gratitude for them breaking the cursed ice that had encased him in the Quidditch Changing Rooms, thus unknowingly saving his life.

#### Tulip Karasu

Yasuko got along with Tulip Karasu and they teamed up seeking the Cursed Vaults. Although Tulip had in fact betrayed Merula for a better chance at actually finding the vaults, she later came to regret this and Yasuko helped to ease her guilt, with Merula working with them both in the future. In spite of this, Tulip was surprised that Yasuko did not have a grudge against Merula or distrust her entirely.

#### Skye Parkin

Yasuko bonded with Skye Parkin over their shared passion for Quidditch, though she was annoyed with her zealous attitude. Both of them were able to work effectively together as two units on the same team over a common objective of winning the House Cup.

#### Murphy McNully

Yasuko bonded with Murphy McNully over their shared passion for Quidditch, though she was annoyed with his excessive talking. Both of them were able to work effectively together as two units on the same team over a common objective of winning the House Cup.

#### Orion Amari

Yasuko bonded with Orion Amari over their shared passion for Quidditch, though she was annoyed with his old-fashioned, almost medieval rhetoric. Both of them were able to work effectively together as two units on the same team over a common objective of winning the House Cup.

### Others

#### Merula Snyde

"*There are so many things at Hogwarts you're not smart enough to understand,* Yasuko Rivera*. Trying to uncover those things is going to get you killed...*"
— Merula Snyde
Merula Snyde became the archrival of Yasuko Rivera almost immediately upon arriving at Hogwarts. Merula came from a supremacist family and desired to surpass all others, thus she considered herself superior to virtually everyone. She bullied Yasuko for allegedly being cursed, though she did not truly hate Merula and merely wished she would leave her alone. She first met when Merula tried to force Rowan Khanna into claiming she was the most powerful witch in the wizarding world, and she baffled her by already knowing who she was. Yasuko learned she was born of two Death Eaters, and while it made her realise why she was a bully, it did not soften their mutual enmity at all. She was forced to resort to violence when Merula antagonised her and again when she antagonised Ben Copper. During their first round, Merula bested her with a Trip Jinx, but she bested her the second time via the Disarming Charm. She was forced to challenge her a third time in their second year, and while Merula agreed to no more duelling, she refused to stay off her tail. They were also enemies because they both sought to find the Cursed Vaults, albeit for different reasons. When Yasuko arrived with Rowan Khanna and another friend, she used the Trip Jinx against all three of them, confusing Yasuko who did not understand why she wanted to solve the mystery as much as he did. She believed they were going to meet a sticky end someday. Despite being enemies, they began getting along better when Patricia Rakepick recruited the both of them as apprentices.
#### Ismelda Murk

Ismelda Murk used to despise Yasuko for the threat she posed to Merula's chances of finding the Cursed Vaults, but after she helped her resolve her enmity with Erika Rath and her obsession with Barnaby Lee, their relationship grew less hostile.

### Hogwarts staff

"*The only thing I value less than you, Ms. Rivera, is the way Ms. Snyde is treating you. Sit down.*"
— Severus Prince-Slytherin
Yasuko generally had a positive relationship with the staff at Hogwarts, who were all impressed by her academic prowess. However, she was also looked at with apprehension because of Jacob, and was looked at with particular apprehension for her wrongdoings. She generally got along with Filius Flitwick, though he hesitated teaching her the Trip Jinx. She also had a good relationship with Rubeus Hagrid and frequently came to his rescue. Her worst relationship, inevitably, was with Severus Prince-Slytherin, who used to treated her with contempt and frequently looked for reasons to take House Points from her. He was never fair with her either, such as when he gave her a single point for making a better potion than Merula Snyde, whom he pretended to like when he actually despised her. Severus eventually began to trust her and started treating her like a daughter after he started a family. Her best relationship was of course with Albus Dumbledore, who openly acknowledged her magical prowess to be exemplary and treated them with nothing but respect and kindness and none of the apprehension the other staff members did for her wrongdoings and actually expressed sympathy for her, to the point where he even gave them House Points for saving Hogwarts from three of the curses of the Cursed Vaults. Even though Dumbledore could get stern and firm with Yasuko, it was for her own good and apart from punishing her to constant detentions with Pitts, he had defended her from practically all of the staff's criticism.
#### Patricia Rakepick

Presumably well aware of the events that lead to the expulsion of former Hogwarts student Jacob long before she ever met his younger sister, given her own interest in the vaults, Patricia Rakepick took interest in the latter individual for their first-hand experience with the Cursed Vaults, and was known to have kept an eye on her, possibly even before she was invited back to Hogwarts by the Headmaster of the day, Albus Dumbledore, to help put the threat of the Cursed Vaults to rest. Though she did not waste any time soliciting the help of said student and her group of friends to make her own, sanctioned search for the vaults easier, and even assured Yasuko she meant her no harm and even were investigating the identity of the mysterious wizard that had attacked her in the Clock Tower Courtyard after curfew by forging a letter with the handwriting of Silvanus Kettleburn. Severus Prince-Slytherin, formerly Snape, however, the Potions Master and former schoolmate of Rakepick's, did not trust her at all, going so far as to saying she had ulterior motives for being at Hogwarts and that she was after the Cursed Vaults for her own gain, and quite possibly meant to kill both her and anyone else who stood in her way. Rakepick continued, however, to request the assistance of Yasuko, teaching her the Shield Charm to test her abilities and, getting impressive results, continued to offer guidance, such as lending her her own Niffler to help in the search for clues and eventually teaching her the Spider repelling spell in order to prepare them for a potential fight with Acromantulas.

In the end, however, Severus's suspicions were proven partially correct when she fooled Yasuko into breaking into the office of Argus Filch for a wild goose chase, only to swoop in and retrieve something she herself had been looking for. This eventually left Yasuko uncertain if Rakepick can be trusted or if she was playing right into the hand of her potential enemy. Rakepick did redeem herself for her indiscretions, however, when she saved the life of Yasuko by coming to her rescue just as her attacker was about to deliver the *coup de grace*, casting a Blasting Curse so powerful that the attacker was blasted backwards, across almost the whole length of the Clocktower Courtyard and into a wall, knocking them out cold. Upon undoing the Disillusionment Charm the attacker was under, she discovered that the person in question was Ben Copper, whom Rakepick transported back into the castle to prevent him from hurting himself or others while Yasuko went after the Forest Vault.
