ONA
Description
Kuriko is the central figure in the short story “The Bully,” which appears within the anthology. The following character description focuses on the adult version of Kuriko as depicted in that adaptation.

During her childhood, Kuriko was placed in charge of looking after a younger boy named Nao. When she grew irritated by his clingy behavior, she responded with cruel and escalating acts of bullying. She screamed into his ear, forced him to drink dirty water, goaded him into being attacked by a dog, and beat him with a stick. This pattern of violent domination set the foundation for her adult self.

As an adult, Kuriko initially presents herself as a woman seeking atonement. She is in a relationship with a man named Yutaro and, before their marriage, decides to confess the details of her dark past. In this moment she appears remorseful and burdened by guilt, as though hoping that honesty will free her from what she once did. Yutaro receives her confession with forgiveness, and for a time it seems she might have moved beyond her younger cruelty.

However, the story reveals that Kuriko eventually leaves Yutaro for Nao, who has returned to her life as a charming adult. Nao seduces her and they marry, later having a son named Hiroshi. This relationship turns out to be Nao’s calculated revenge: after they have built a life together, he abandons her, leaving her with a child who closely resembles him. The abandonment shatters the stability she had appeared to gain, and her buried violent nature resurfaces.

In her adult state after being left, Kuriko becomes psychologically unmoored. She begins to abuse Hiroshi in the same ways she once abused Nao, mistaking the child for her former victim. She convinces herself that Hiroshi, like Nao, secretly wants and enjoys being punished, framing her abuse as something the boy invites. This delusion allows her to justify a full relapse into her childhood behavior. Her demeanor shifts from a woman who once sought confession to someone who wears a crazed expression while preparing to take her son to the same park where she tormented Nao, ready to repeat the cycle of harm.

Kuriko’s personality as an adult is marked by a veneer of normalcy that conceals a deep, unaddressed cruelty. When she feels in control, she can appear sweet and repentant, but when she feels rejected or trapped, she transforms into a figure of domestic horror. She is not a supernatural being but a human antagonist defined entirely by her capacity for sustained psychological and physical abuse. Her motivations swing between a superficial desire to be seen as good and an overwhelming compulsion to dominate those she considers weak, especially when her own emotional wounds are exposed. She does not possess notable abilities in a supernatural sense; her power lies in manipulation and the terror she inflicts on those closest to her. The adult Kuriko ultimately embodies the story’s theme that without true change, a bully’s nature can lie dormant only to reemerge when circumstances echo the past.
