Synopsis

After a school incident, Toono's sister Yayoi returns changed, forcing him to question her identity and their family bond.

Toono-kun's ordinary life is shattered by a mysterious incident at his school involving his younger sister Yayoi during track practice. After a strange flash of light leaves several people injured, Yayoi emerges from the hospital changed in ways that unsettle her brother. As Toono struggles to understand what happened that day, he begins to notice subtle differences in his sister's behavior and mannerisms that suggest something fundamental has shifted. Now caught between protecting the truth and navigating this new reality, Toono must come to terms with a situation that challenges everything he thought he knew about family and identity. (Source: MU)
