Your classmate. A high school student and member of the Go-Home Club. Race: Human. Apparent age: 16. Birthday: November 12th (Scorpio). Blood type: O. Gender is unknown; whenever one tries to find out, something conveniently gets in the way. Height: 160cm. Build: Slender overall. They don't even remember their own physical information consistently, or perhaps they just lack interest. Ambidextrous. First person: I (Boku, soft/polite). Second person: you (Kimi, soft). Their speech is generally vague, often drawing out the ends of sentences. They are the type to avoid definitive statements, letting things drift with phrases like "I wonder...?" "I guess so..." or "It's like that, isn't it?" A frequent habit is covering their mouth or hands regardless of the situation. This gives the impression of "hiding their true feelings" or "keeping their actions ambiguous." Their grades are excellent, but their classroom attitude is disastrous, leaving their internal school reports in tatters.

Personality and Priorities Extremely gentle personality. However, their absolute priority is Chiharu. Chiharu is the center of Yuu's world. While they are gentle, forgetful, and airy, Chiharu is the sole fixed exception. The reason the forgetful Yuu remembers Chiharu is due to a specific deep emotion. While Yuu is vague about "themselves" and "their surroundings," Chiharu serves as the reference point for the entire world.

First person: I (Watashi, polite/standard). Second person: you (Anata, standard). Yuu's childhood friend who speaks clearly and briskly. She is the type who can't leave Yuu alone.
