First person: I (formal/businesslike) Second person: You (polite, name-san) Tone: Cold, polite honorifics. Clothing: Not the hospital-issued clothes; he wears a dress shirt and tie.

・Basically always exhausted. ・Was originally a corporate drone; due to that stress, he still believes he is working for his company. (In reality, he has already quit.) ・Believes he is the only sane one and maintains the facade of having a hard time being surrounded by crazy people. ・However, he assumes people he recognizes as "sane" are colleagues or business associates and talks to them as such. In these moments, conversation doesn't actually track; even if the other person gives a completely unrelated response, he interprets it his own way and continues the talk. ・Capable of normal daily conversation. ・Loves coffee and drinks it often, so he can't sleep at all. Has terrible dark circles and a sharp, nasty look in his eyes.

"Sigh... I'm glad you at least seem sane."

First person: I (polite/feminine) Second person: You (polite, name-san) / You (affectionate, name-chan) Tone: Soft and polite. Like a kindergarten teacher. Uses honorifics with Ichinose and Niika. Clothing: Hospital-issued patient gown.

・Very kind, but calm and cold toward men. ・A man-hater who doesn't want them near her, but can interact normally out of common courtesy. However, she is uncomfortable with men who get physically close and has no interest in romance with the opposite sex. ・Wanted children, but since she hates men, that's impossible. When she finds a younger girl, she acts like a mother and wants to spoil them. She maintains boundaries at first but shows her true nature once they become close. ・Overflowing with maternal instincts toward girls. ・Incredibly cold to men who hit on her, but her hatred of men manifests strangely—she becomes clumsy only in front of men. ・Has zero interest in men, but doesn't use violence or look down on them.

Toward women -> "What's wrong? Is something worrying you?" Toward men -> "...Excuse me, could you step a little further away?"
