Ume Shabana

Ume Adagaki (neé Shabana) (安達垣 梅, *Adagaki Ume*) is one of the main characters of *Kimetsu no Isekai*.

## Appearance

Ume is a tall, curvaceous, beautiful 16yr/old second-year girl with long, neatly-brushed white hair with messy bangs along with pale skin and lipstick with lapis blue eyes and long lashes. She’s one of the three most beautiful girls in the country.

She’s typically seen wearing her school uniform, which is a loosely-fitted white blouse put together with a yellow tie that has an intricate, green hexagonal pattern along with her skirt. Her hair is worn down, neatly brushed and styled together, and she wears black loafers with white stockings.

After Aki and Kizuki Jr. are born, Ume wears a brown plaid pinafore dress with short white sleeves and white stockings with brown loafers. Her hair is still mostly worn down, but she has a white fluffy ponytail tied on the back of her head.

When Ume becomes queen she is always seen either wearing an elegant dress with extravagant jewels and a ponytail/royal hair style or a casual silver silk gown and hair worn down.

## Personality

Ume possesses an easily influenced, impressionable and honest personality, causing her to easily take up the personality traits and words of those she trusts and admired to heart. She displays childish and bratty tendencies such as throwing tantrums, crying hysterically when things didn't go her way, and lashing out against anyone to vent her frustrations. Putting her venomous hostility on full display numerous times, she was both verbally and physically abusive towards anybody that displeased her in any way.

After meeting Kizuki she began to mature, her façade of being nice starting to transform into a genuine interaction. She still retained her tsundere personality, but stopped throwing tantrums and instead went to Kizuki to verbally vent her frustrations. She began to rely on Kizuki for her emotional stability, eventually forming an emotional attachment and even falling in love with him.

Unfortunately, at the time, Kizuki was engaged to Yuki Matsuda, so Ume stuck to bottling her feelings and acting friendly. Once Kizuki fell under the Blue Spider-Lily Curse and was unable to be awakened by Yuki, Ume decided to wake him herself, successfully doing so. After realizing what she had done, she became distant for a while until Kizuki’s near-death experience with Muzan at the Ubuyashiki Academy, prompting her to force him to ask her out.

As their relationship progressed, Ume fell deeply in love with Kizuki, to the point thinking about being with another man disgusted her. She is undoubtedly loyal to him, giving him all the love she has and spoiling him with affection whenever she could. She also deeply loves her children, realizing that the life she gained with Kizuki was something she’d never trade for anything else in the world.

## History

### Childhood

Born to Yuto and Akane Shabana, Ume was the half-sister of Gyutaro and beloved crown princess of the Shabana Kingdom. Her royal upbringing caused her to be entitled and spoiled, as her father Yuto showered her with privileges and gifts, while her mom resented her and trash-talked her whenever she could.

As Ume grew older she began to grow bored of the royal life, gaining exhaustion from constantly dressing up and being holed up in a castle all day. Gyutaro proceeded to take Ume and show her a more “fun” side to life, introducing her to the delinquent lifestyle and causing her entitled behavior to worsen as she began to believe that not only could she get what she wanted without asking, but could also get what she wanted by force, which caused her to gain a notorious and violent reputation.

Her and Gyutaro eventually met Muzan, who took a brief interest in them for their abilities which they frequently showcased while committing petty thievery and such. With the permission of the Shabana Family, Muzan then enrolled Ume and Gyutaro into the Kibutsuji Academy at the early ages of 13 and 15, where he conditioned, influenced, manipulated and trained them into the perfect students for his bidding alongside his other students.

### Kibutsuji Academy

This went on for 3 years until Muzan opened the Academy for the newest semester, prompting the arrival of Kizuki, Kaihō’s Crown Prince and heir to the throne (which Muzan deliberately planned in order to put his plan into action). Ume was given the task of seducing and gaining Kizuki’s trust in order to eventually inherit the kingdom by proxy of Muzan, allowing him to rule the country through her without needing to directly handle its affairs.

She began to attempt to befriend Kizuki after a bad first impression, Kizuki’s display of immeasurable power scaring her and Gyutaro into the benevolent route, with Muzan manipulating the circumstances in order to get them to share a room. Kizuki, at the time, was engaged to Yuki Matsuda, and was in love with her. Ume continued her façade, though, which lead to her friendship with him becoming genuine.

Unbeknownst to her, Muzan could care less about her and easily detected the change, using it to his advantage to eventually manipulate Ume without any choice after she backed out once Muzan began to attack Kizuki with the Top 5 Students.

After the final battle and Muzan’s defeat, Kizuki discovers that Ume was manipulating him all along—causing him to break off the friendship, telling her it was wrong to use him and then let herself be used. It was also revealed that her special arts was actually her blood being manipulated by Muzan, causing her to be downgraded into the normal dorms. Saddened by the realization of everything, she sought to reconcile their friendship and show him that she truly did see something in it.

### Matsuda Kingdom

She was let into his life again, and they started to slowly repair what she had broke, until Kizuki was called to help save the Matsuda Kingdom from Yuki’s brother, Ryōsuke. She offered to tag along, hoping to show that she really did want to change and wanted to help do good for the people. Assisting Kizuki with Yuki and her family to save their kingdom helped her reputation to begin improving, and her and Kizuki slowly began to reform some semblance of a friendship.

### Spider-Lily Arc

Swiftly after that, Ume and the rest of them return to their normal academy life, until one day in botany class they’re taught about the Blue Spider-Lily flower and brought on a field trip into the forest, where they lose Kizuki and find him unconscious in a field of Blue Spider-Lillies.

Wondering what to do, it is revealed that only True Love’s Kiss could awaken him, which causes Ume to shy away from the situation. Unbeknownst to her, the witch who grew the field of flowers and lured Kizuki into it, Chieko Nishamoto, was well aware of Ume and her fate with Kizuki.

Ume and Yuki meet Chieko as a lost villager girl and befriending her. Ume one day wakes up in Chieko’s body, which causes her not only anger, but extreme confusion as she figures out what’s going on. Chieko, in her body, begins to manipulate and fool everyone into making them believe she truly was Ume in order to awaken Kizuki and take over the Adagaki Kingdom.

Overhearing Chieko’s plan after evesdropping, she attempts to confess the truth to Yuki, but was denied until revealing secret information about herself nobody else knew about. Finally being recognized, Ume and Yuki start to plan how to catch Chieko in the act, and in their research realize Chieko is an ancient witch who uses Spider-Lillies on ancient heroes in order to attempt to manipulate history to her bidding,

They figure out the spell Chieko uses and utilizes it to switch Ume and her back, before proceeding to confront Chieko about everything. Angered by their interference, she attempts to kill them before being immobilized by an annoyed Ume and chucked into the field of flowers.

Later on, Yuki attempts to awaken Kizuki while Ume watches from the distance, but grows surprised as the kiss doesn’t awaken him. Walking over after watching Yuki depart, she leans down and kisses him in order to confess her love, thinking he wouldn’t awaken. She then walks away, but unknown to her, Kizuki awakens shortly after.

### Ubuyashiki Academy

News breaks out that Muzan had escaped prison, with Michikatsu receiving a letter from Kagaya requesting assistance with Ubuyashiki Academy. Ume, Kizuki, and Yuki are sent to assist them, and Ume watches as Kizuki and Yuki begin to start distancing and having frequent arguments.

She chooses to distance herself from Kizuki due to the Spider-Lily incident but finds it difficult to as he attempts to chase her down. She eventually finds herself kidnapped by a now-transformed Muzan, who starts to go on a rant about how demons blood can provide true power. Kizuki then saves her, in which his near-death experience with Muzan prompts her to force him to ask her out. They quickly became a couple after.

### Jigoku Cult

Though they succeeded, Jigoku ended up breaking free, Aki and Kizuki Jr. from ten years in the future travel back in time to save Kizuki from his impending death in the final battle with Jigoku. Kizuki eventually discovers that Jigoku is his grandfather, and that, he is in fact, a powerful demon lord from a family of powerful devils.

### Final Reincarnation Arc

Ume attempts to grapple with the fact Kizuki is a demon lord with the blood of a god, before discovering that she and Kizuki have children together in the future. The children, Aki and Kizuki Jr., explain that Kizuki dies in the impending battle with Jigoku, causing the future to become doomed, which they reveal is why they chose to travel back—in order to save their father and the future.

Coming to terms with his heritage, she reluctantly agrees to their circumstances and the future, realizing that if she truly loved him, none of what happened would matter. Ume and the kids help Kizuki prepare for the battle, which eventually leads to the two cementing the children’s future.

Left asleep through the entire battle after her and Kizuki’s encounter, she wakes up to the battle ending, rushing outside to find Kizuki unconscious. Their kids reveal that Kizuki is alive and well, and that the future has been saved, but the price for this is that he has been put into a coma due to excessive use of magical and physical energy all at once. Devastated but thankful, she gives the kids a tearful goodbye before watching them fade away.

### Aftermath

Exactly a year had passed since Kizuki's coma, in which Ume had isolated herself, pushing every man away, afraid her children would mistaken them for their father. She took great measures to prevent that, playing his voice everyday while she was pregnant and bringing them to see Kizuki after they were born so they could feel and see their father for the first time. In Kizuki's absence she raised her newborns in a small house inside of town near the castle.

A neighbor, Jiro, helped her raise the kids as she was left a single mother. The children were now about four months old during this time in which Kizuki woke up. When the news was revealed to her, she rushed over to find Kizuki awake, and explained everything to him while crying into his arms. She then leads Kizuki to the kids, who he sees playing with Jiro, causing him to have a fit of jealousy.

Ume proceeds to diffuse the situation and calm him down, reassuring him Jiro was only a friend and there to help her during a dire time of need, as raising two children along was an exhausting task. Kizuki remained doubtful, but then reassured, and the two quickly went to rebuilding their life together.

Not much later, Kizuki’s parents invite her to the castle, revealing her to eventually be wed to Kizuki and offering her immortality. Excited, she agrees and begins to plan their wedding until the day came, in which they have a lovely, intimate, and extravagant wedding, where they initiated the ritual to make her immortal. Pronounced husband and wife, they then announce it to be coronation day as well, much to Kizuki’s dismay.

They are then crowned King and Queen, announcing their vows to themselves and the country, cementing the beginning of a new era. The two then run off to the garden to consummate their new marriage, ending their story and beginning their lives together.
