Kagamihara Sora

Because of Kagari, who is too special for him, he is only recognized as “Kagari's older brother” by those around him, and he spends his days in depression.

Although Kagari is the only person to whom he can express his true feelings, she is the source of his complex.

One day, he mistakenly believes that Kagari has destroyed his relationship with a girl he had a crush on. The pent-up anger explodes and he begins to humiliate his sister.
