Ruri

Name: Ruri

Gender: Female

Age: 18

Date of Birth: April 14

Blood Type: O

Ruri serves as the hereditary shrine maiden of her village, a position passed down through generations.

Due to this role, she is central to the village’s traditions, history, and religious customs.

She is the older sister of Kohaku and grew up in the same village as Chrome.

Although physically close, her status as a priestess and her poor health created emotional distance from most villagers for many years.

Ruri has inherited the “One Hundred Tales,” a large body of oral stories transmitted from shrine maiden to shrine maiden.

These stories include the legend of “Momotaro” as well as accounts of unusual animals and advanced vocabulary rarely known in her isolated world.

Thanks to the One Hundred Tales, she possesses knowledge that seems uncanny to the villagers.

Her familiarity with strange words and concepts marks her as unusually educated for someone in a primitive setting.

She appears to recognize Senkuu Ishigami at their first meeting, even though they have never met before.

This reaction occurs because Senkuu is actually mentioned within the One Hundred Tales, linking her inherited lore directly to the scientist from the ancient world.

Ruri was chronically ill for much of her life and was considered physically fragile.

Her sickness limited her movements and interactions, especially compared to her active sister Kohaku.

After Senkuu Ishigami completes a sulfa-based medicine, Ruri takes the drug as treatment.

Her strong positive reaction confirms that she had been suffering from pneumonia.

Once her pneumonia is cured, her true physical potential becomes clear.

She starts moving with a level of energy and athleticism that astonishes the villagers, showing that, like Kohaku, she naturally possesses high physical abilities.

Following her recovery, Ruri begins to take part in practical labor around the village.

She no longer remains a passive, bedridden figure and instead joins the community’s daily efforts.

She helps with tasks such as wine production.

She also contributes to the manufacturing of manganese batteries, supporting the scientific projects that are transforming village life.

Her involvement reflects a shift from ceremonial duties to active participation in the developing “Kingdom of Science.”

This change shows how her role evolves from guardian of old stories to a contributor to new technological progress.

With Kohaku

Ruri is the older sister of Kohaku, who deeply cares about her well-being.

Their bond is strengthened as Ruri’s health improves, allowing them to interact more freely and on equal footing.

Like Kohaku, Ruri has strong natural physical capabilities that only fully emerge after her recovery.

The sisters share a similar vigor and spirit once Ruri is no longer constrained by illness.

With Chrome

Ruri and Chrome were childhood playmates and spent a lot of time together when they were young.

They were close as children, but circumstances gradually pushed them apart.

As Ruri grew into her role as shrine maiden and her illness worsened, a sense of distance formed between them.

Despite living in the same village, their relationship came to feel like that of distant relatives rather than close friends.

After Ruri’s illness is cured, that emotional barrier begins to crumble.

She and Chrome return to chatting and interacting the way they did in the past, reviving their old, warm friendship.
