Ruri

* Anime
* Manga

**Ruri** (ルリ, *****Ruri*****) is a descendant of modern-day humans. She is Kohaku's elder sister and the daughter of Kokuyo, and serves as the priestess in Ishigami Village.

## Appearance

Ruri is a young woman with a delicate face, long blonde hair, and blue-green eyes. Her hair reaches her waist, and is cut in choppy layers at her shoulders, chin, and eyebrows. Her eyebrows and lips are thin, while her eyes are large with a slight point towards the upper outer edge, giving her a calming, mature expression. She appears to have a mix of Japanese and American descent, denoting her heritage as a descendant of Lillian Weinberg. She shares similar facial features with her younger sister, Kohaku, but has longer, squarer hair that she wears down rather than up in a ponytail. Ginro crudely pointed out that Ruri has bigger breasts than Kohaku.[*Citation needed*]

She wears a primitively-made blue sundress that reaches her ankles, with a split along her left leg, going up to her waist. It is clasped in three places along her thigh for modesty. High on her waist, she wears a thin rope tied into the shape of the village's star-shaped symbol, and wears the village rope around her neck. She also wears the same sort of heeled shoes as the rest of the village. When Yuzuriha built a fashion store, Ruri wore a more modern dress.

## Personality

Ruri is a gentle, kind, and noble young woman with an aggressive personality that occasionally comes out when she's not acting as priestess nor dying of pneumonia. She has incredibly strong willpower, surviving pneumonia through sheer will and Kohaku's help.

In Ruri's mind, acting as priestess for the village comes first: she was willing to marry whoever won the Grand Bout as was tradition, and diligently memorized all 100 Tales in two years before her mother died. She also tried passing the tales to Kohaku before she died, but Kohaku refused, which may have helped Ruri's determination to survive rather than accept her fate of a short life.

She cares a lot about Kohaku, her younger sister, and frets over her. When she noticed that Kohaku's hair was tied differently, she expresses concern over Kohaku behaving recklessly and getting into accidents. Ruri pleads to her to take care of herself better, for her sake. When they reunite after Ruri's revival, Kohaku is the first one Ruri goes to to hug.

After recovering from her illness, she is shown to be just as much of a tomboy as Kohaku, breaking into a sprint as soon as she is let loose. Her keen memory and ability to learn quickly puts her in charge of building the dam. She also helps Senku with solving the mystery of where the villagers came from by pooling her knowledge of the Hundred Tales and his knowledge of the modern world.

## Abilities

* **Enhanced Memory**: Able to memorize the Hundred Tales perfectly, Ruri is shown to have an incredible memory.

* **Acute Observation**: Ruri possesses sharp observation skills, noticing details such as Kohaku retying her hair, Minami's affection for Tsukasa, and noticing Chrome grew up.

* **Religious Leadership**: Ruri's position as the village priestess means that she has leadership abilities. This can be seen when she issues commands to Jasper and Turquoise during the village attack by Homura. In the anime, it was elaborated that it was her who told Kokuyo to pass his position of chief onto Senku.[*Citation needed*]

* **Gorilla Strength**: Ruri is shown to share Kohaku's athletic prowess, as her first instinct when she is cured is to sprint off into a field at high speed. She is also strong, as she can easily pick Kohaku up and throw her around.

* **Handicrafts**: Cooped up in the chief's hut with her illness allowed her to practice her handicraft skills, shown by her providing a sewing needle for the record player. Previously, she had also helped Gen craft the hundreds of manganese batteries for the cellphone.

* **Resistance to Romance**: Ruri appears incapable of having a romantic moment. First, she is divorced by Senku within minutes of their marriage, then has absolutely no luck with getting Chrome to acknowledge her as a potential romantic partner until the very end, where his proposal is completely tactless.

## History

Ruri was born to the Village Chief in Ishigami Village eighteen years prior to Senku's arrival. The Hundred Tales are told to her as if they were lullabies. Two years later, Kohaku is born.

As a child, she befriended Chrome, with whom she spent a lot of time playing outdoors with. At 12 years old, she gets pneumonia, and was told by the village elders that she wouldn't live long. Chrome promised her that he would search everywhere and turn every stone in the search for a cure, while Kohaku tried helping her illness by carrying hot spring water for her to bathe in. At 14, she inherits the Hundred Tales from her mother, and at 15, her mother dies.

When she turns 18 years old, the first Grand Bout is held.

## Synopsis

### **Kingdom of Science Arc**

Ruri is introduced as the village priestess. Kohaku brings her water, and Ruri requests that her guards leave the sisters alone for a moment. As the two finally leave, Ruri scolds Kohaku to take care of herself, since she deduced something must've happened to cause Kohaku's ponytail to come undone.

### **Village Games Arc**

Once Senku finally steps foot into the village, Ruri recalls his name being familiar. She approaches Senku and asks what his family name is, most villagers not knowing what that means. When she mutters the first few letters of Senku's surname, she collapses, weakened from her disease.

Ruri is relieved to see Chrome win the battle against Magma. Ginro takes note that he is aware Ruri wants Chrome to win and that she shouldn't worry as Senku will surrender the match. Out of respect for her position, the priestess states that she doesn't possess such desires and that since this is a divine festival, she will accept whomever wins the competition. A confused Ginro then wrongly concludes that she is indeed fine with any winner and maniacally attacks Senku, only to be defeated and thrown out of the competition. Senku them moves into the finals, where Chrome faints due to his previous fight with Magma, thereby making Senku the winner, much to Ruri's shock.

After Senku wins the village tournament by accident, he was in the position where he would be crowned chief and take over the village if he chose to marry Ruri, and much to her shock, he does without hesitation. A few minutes later, she starts coughing blood into her hands. Noting that they must finish the medicine as soon as possible, Senku calls all the science team to leave with him back to the lab, but when Genbu stops him saying they must celebrate his wedding, Senku, with just as little hesitation, demands a divorce. Shocked and astonished, her and the villagers watch as Senku and company flee the scene, taking them the wine and vinegar the villagers had brought out. Ruri pointed out that to her knowledge, she was the first ever divorced priestess.

After Senku diagnosed Ruri with pneumonia, she was willing to take the risk of modern-day medicine, consuming antibiotics for the first time. After swallowing the antibiotic Senku gave her, she is inspected by the latter who concludes there is a fluid buildup in her lungs. A little while later, her condition suddenly turns to worse, with Jasper commenting that he has never seen her in such a state. Kokuyo blames Senku on her current condition and grabs him. Senku agrees that the sulfa drug could have caused her to get sicker, shocking the group. However, he goes on to explain that the targeted bacteria is mobilizing more reinforcements now that its existence is threatened, a special ability of streptococcus pneumoniae.

Senku declares victory over the pathogen as the drug they made will kill the bacteria. Kokuyo frustratingly attacks Senku again, only to be stopped by Kohaku, who states that she believes in science and in Senku. The rest of the group nods in unison. After taking continuous doses of the drug, Ruri eventually overcomes the disease, being able to walk normally again. Kokuyo and Kohaku cry tears of happiness as Ruri celebrates her recovery by running, having forgotten the last time she stepped out of the village or was active at all.

### **Village Origins Arc**

Once Kokuyo accepts Senku as the new village chief, the latter comes to know the name of the village being Ishigami. He is then approached by Ruri who informs Senku she's always known his full name - that being Senku Ishigami. Ruri reveals that Ishigami Village was founded by Byakuya Ishigami and his crew, and Senku is widely famous amongst the village community throughout every generation as Ruri fully remembered her mother’s story about Senku—the last of the hundred tales passed throughout the village's generations. Her explanation causes Senku to understand why there are still humans around.

She tells Chrome, Kohaku and Senku about this tale, then as they celebrate, she leads Senku to the village cemetery, where he is presented with Byakuya's grave marker, brought over from the island they landed in. She lets Senku know the last part of the story she doesn't usually tell, a message to Senku from Byakuya. Once she conveys the tale, she leaves Senku alone at his father's grave while shedding a tear herself.

### **Vs. Hyoga Arc**

When Homura sets the village ablaze, Ruri tells the worried Jasper and Turquoise to forget her and rescue the children. She enjoys the wonders of a new sweet called cotton candy made by Senku along with her sister. As Senku goads Homura into trying the candy, Ruri recognizes that Senku didn't offer her such pleasure purely for strategic purposes, but also for comfort as she was spying on them all alone for exceedingly long periods of time.

### **Communications Arc**

Ruri is present when Senku creates cotton candy and is amazed by the taste. She aids in making batteries and is seen helping create wine. The priestess is seen once again, now admiring the newly brought jewels from Senku, Chrome and Magma's cave expedition.

When the phone is complete, the village tried to encourage Chrome to confess his feelings to Ruri through the stone world's first telephone call, though he instead cheers to her about how great science is, and this brings a smile to her. After comparing Senku's phone to a bee and telling him a tale about a bee communicating with the dead, he realizes that Byakuya left a recording message for him.

Once the record player is made, Ruri is amazed by hearing the recording of Senku's father and the song sung by Lillian Weinberg.

### **Age of Exploration Arc**

Ruri is encouraged by Ginro to confess to Chrome, she blushes at the notion and tries to go through with it but fails because of their call being interrupted by Why-man.

### **Treasure Island Arc**

Ruri tells Senku about the 100 tales and she bores him with most of them. Very soon, she tells him about the islanders where the founders originally landed.

While on route to Treasure Island, the Perseus crew contact Japan and update the people who stayed behind on there being other Stone World humans elsewhere. Ruri was amazed by the possibility and deduced they may be distant relatives of a branch who set for Japan.

After the conflict on Treasure Island is done, Ruri soon contacts Senku and he updates her.

### **New America City Arc**

Ruri is happy when the Perseus returns and to see that the modern people have lost their scars, meaning they found the secret of petrification. Indeed, Chrome reveals the Petrification Weapon and Ruri remarks that the dreaded petrification can now be used to heal everyone. After Tsukasa is revived, she watches Minami choose to let him reunite with his sister first but Ruri pushed her into talking to him, while Nikki notes on Ruri's assertive nature.

### **South America Arc**

She witnesses the Petrification beam heading over the horizon. Her father then has her and the villagers curl into a defensive position so they will not be damaged while petrified. She is then petrified with the villagers.

### **Globetrotting Arc**

Nine years after petrifying, Ruri and the others were revived by the returning members of the Kingdom of Science. She picks up her sister in their reunion, while Kohaku comments she hasn't changed a bit. Ruri reunites with Chrome (who was punished by Kohaku for calling them gorillas) and is hopeful when he talks with her but takes it in stride at his usual obliviousness. She soon explains she and the others did not create the wall, which protected the petrified villagers before it is revealed that it was made by Sagara and Chalk.

### **Moon Mission Arc**

Ruri helps complete the dam's construction, and is amazed by Senku's final burst of modern appliances, especially the microwave. When the rocket is finally complete, she bids are tearful farewell to her sister, telling her to take care and to come home safe. At the very end of the story, Chrome proposed to her, but left her confused due to his bluntness and no date was set for the marriage.

Once civilization returned, Ruri found a job helping Yuzuriha with her fashion company.
