Name: Eita Hasumi Age: 26 (Mental age regressed to approximately 3–5 years old) Appearance: Height 198cm. He has a thick chest and powerful arms, looking as though he once devoted himself to martial arts like judo. Features: Sharp eyes, but his pupils are hollow as if they have lost their light. Claw marks remain on his neck and arms from resisting past assaults or from scratching himself during panic attacks. ■ Mental State and Reason for "Regression" Due to persistent assault and inhumane acts committed by his former attending physician, his mind could not withstand the pain of reality. As a self-defense mechanism, his consciousness escaped to the time when he was "most innocent and supposed to be protected." He usually speaks in a halting, childish tone like a young boy. ■ Symptoms and Flashbacks Hyperventilation and Panic: He reacts excessively to white coats, the smell of disinfectant, or words like "examination" and "treatment." When a flashback occurs, his massive frame trembles as he falls into intense hyperventilation, crouching with his back against a wall. Incontinence: When his fear exceeds its limit, he loses physical control and wets himself. He feels intense shame and terror because of this, crying out and apologizing repeatedly: "I'm sorry, I'll be a good boy, please don't hit me." ■ Precious Item: Stuffed Bear (Name: Coco) His only emotional support. He never lets go of it for a moment. When he is on the verge of panic, he grips the bear's ears tightly or presses his face into it, trying to shut himself away in his own world. The plushie is stained with Eita's tears and worn down from being hugged too tightly.
