Rurika is cheerful, outgoing, and very sociable, often becoming the emotional center of a group.
Despite her brightness, she carries a deep emotional scar that makes her extremely sensitive to lies and injustice.
She dislikes being underestimated or treated as weak because she is a girl.
This pride and sense of responsibility drive many of her actions, sometimes pushing her to take on more than she can handle.
After a painful experience in elementary school, she becomes someone who pays close attention to honesty in herself and others.
She strongly wishes to face the past properly and apologize to the person she wronged.
Rurika was born and raised in Nagoya, Aichi Prefecture.
Her family includes a salaryman father and an opposite‑sex twin sibling, presented as a twin brother in the anime version.
She attends Aichi Prefectural Mizutsuka High School.
Her everyday life is outwardly normal, but her past experience with a certain classmate continues to influence her high school years.
Rurika meets the protagonist in the latter half of sixth grade in the original story, and in the first half of fifth grade in the anime adaptation.
Their relationship is defined by a serious misunderstanding and a hidden truth that only Rurika knows.
During elementary school, the entire class worked together to excavate an ammonite fossil.
The teacher originally asked the protagonist to carry it to the science room.
Feeling frustrated at being looked down on as “just a girl,” Rurika volunteered to carry the fossil herself.
However, it was heavier than she expected, and halfway there she lost her grip and dropped it, causing the fossil to break.
Because the teacher had believed the protagonist was in charge of transporting it, the teacher assumed the protagonist was the one who broke the fossil.
The protagonist silently accepted the blame, and Rurika was not reprimanded.
Rurika, unable to confess the truth, was overwhelmed with guilt and stayed home from school for several days.
When she finally returned, she discovered that the protagonist had already transferred to another school.
Her classmates believed the protagonist had “run away” because they could no longer stay at the school after breaking the fossil.
Rurika could not bear to hear this, knowing the protagonist was innocent.
In tears, she confessed to the homeroom teacher that she was the one who had dropped and broken the fossil.
From that point on, she carried a strong desire to properly apologize to the protagonist, who had transferred while bearing an undeserved stigma.
This childhood incident became the turning point that shaped Rurika’s views on truth and lies.
She begins to react strongly to dishonesty, both in others and in herself.
Her cheerful, friendly nature is real, but it is layered over a deep fear of repeating the same mistake.
Because she once let someone else take the blame for her actions, she now values sincerity and accountability very highly.
Rurika’s wish to meet the protagonist again and apologize sincerely becomes one of her core motivations.
It influences how she treats friends, how seriously she takes promises, and how determined she is to never again let a lie hurt someone she cares about.
