OVA
Description
Kotaro Satō, a four-year-old boy, independently rents Apartment 203 at Shimizu to hide from his abusive father. He fled his neglectful home after his mother abandoned the family and later died of unknown causes. His father traced him to a foster care facility via an online photo, prompting Kotaro's escape and move to Shimizu.
Despite his age, Kotaro manages daily life alone—cooking, cleaning, and budgeting. Weekly financial support arrives from family lawyer Ayano Kobayashi, delivering money from his deceased mother’s life insurance. Kotaro believes these funds come from a "benefactor," unaware of his mother’s death, though he occasionally questions their origin.
He blends childlike innocence with striking maturity. Kotaro speaks formally, emulating a samurai from his favorite cartoon, Tonosaman, and carries a toy sword for comfort. Past trauma manifests in nightmares and vulnerability, stemming from abuse and starvation.
At Shimizu, Kotaro forms significant bonds: Shin Karino, a struggling manga artist next door, becomes a primary caregiver; Isamu Tamaru acts as a protective father figure, compensating for his estrangement from his own son. He also befriends Mizuki Akitomo, a nightclub hostess in an abusive relationship—after learning of her situation, Kotaro urges her to leave for safety.
He enrolls himself in kindergarten, befriending classmates like Takuya and maintaining a connection with Ryōta, an older friend from foster care who shares his interest in stargazing. Kotaro often displays nuanced understanding of complex emotions, helping others confront struggles while grappling with his unresolved trauma.
A private investigator, Aota, hired by Kotaro’s father, moves into Shimizu to locate him. Upon seeing Kotaro’s scars and recognizing his own abuse history, Aota chooses not to report him. Kotaro demonstrates awareness of Aota’s mission but extends trust after this revelation.
Throughout, Kotaro balances fierce self-reliance with gradual acceptance of support from his found community, showing subtle development in learning to depend on others without sacrificing his core independence.
