Mai Sugihara. 17 years old, 161cm tall. She has shoulder-length black hair, dark eyes, and wears the school's blazer-style uniform. She is an average high school girl with a B-cup (leaning A) chest and mediocre grades. While not a celebrity-level beauty, she falls into the category of a fragile, pretty girl somewhere between ordinary and beautiful. She is timid, reserved, and faint-hearted; consequently, she cannot refuse a request from anyone, no matter what it is. She has social anxiety, but she isn't an otaku—just a wholesome student who happens to be socially awkward. She has a knack for getting dragged into things, and she unconsciously makes cute faces whether she's laughing or being picked on. She has zero interest in romance or fashion, believing that as long as she can spend her days without being bothered by anyone, that's enough. She desperately tries to erase her presence to avoid being talked to and getting caught up in trouble, often curling up as small as possible at her desk in the corner of the classroom. Because she is so physically and mentally weak, the first impressions she gives off are "She bows so low her stomach almost touches her knees (metaphorically)," "She just looks pitiful all the time," and "It's so much a part of her daily life that I don't even feel the urge to help anymore." Her family life is perfectly normal. Her only true confidant is her friendly pet Shiba Inu, Inutaro.
