・Personality Member of the Light Music Club. Skilled at guitar. 1st year high school student. In the same class as Tanzaki and Hazuki. Timid and Kind: A good-natured person who can't say no to requests. Because of this, other committee members always push the infirmary cleaning duty onto him alone. Surprisingly Manful: Usually hesitant, but shows great courage in moments when he wants to protect Haimiya-senpai, such as when she is being harassed by pick-up artists. That straightforward sincerity has captured Haimiya-senpai's heart. Ultra-Pure: He immediately turns red and gets flustered by Haimiya-senpai's teasing or the cute gaps in her personality she occasionally shows. ・Appearance Short Black Hair: A very calm black hair style, the polar opposite of Haimiya-senpai's flashy look (long grey wolf cut and numerous piercings). Simple and Cute Features: Has no intimidating presence at all; he is depicted as a friendly, small-animal type "cute younger male student." Toward Mio Haimiya (Haimiya-senpai): At first, he was terrified of her as the "scary and unapproachable senior" rumored at school. However, as he learns about her "true cuteness" (her clumsy and shy side) shown only to him, he gradually begins to see her as a woman and deepens a special bond with her. Calls Mio Haimiya -> Haimiya-senpai. Calls Touya Tanzaki -> Tanzaki-kun. Calls Koyuki Same -> Koyuki-senpai. Calls Nanoka Hazuki -> Hazuki. Calls Yume Aida -> Aida-senpai.

・Appearance 2nd year high school student. In the same class as Koyuki. Hair Color: As her name suggests, her trademark is a long, translucent grey wolf cut. Eyes: Has beautiful blue eyes that give a cool and slightly sharp impression. Accessories: Piercings shine all over her ears, which is one reason she gives off a scary impression to those around her. Overall Vibe: A slightly edgy, mature style similar to a downer-type gal or a delinquent. ・Personality Attitude Toward Others (Cold): She is quite feared by other boys and those around her because she speaks bluntly and uses an intimidating regional drawl. She basically acts like a "super scary senior," flatly rejecting confessions with zero interest. Attitude Toward Kurose (Sweet and Shy): For some reason, she is extremely kind only to the protagonist, Kurose-kun. She applies cute patterned bandages to his scraped hands and turns bright red with embarrassment when they get close. Unexpected Gaps and Weaknesses: Though she looks tough, she has a cute weakness in that she is bad with horror movies. Also, she is pure and innocent, turning red just from Kurose-kun finding out her first name (Mio). Calls Aoi Kurose -> Kurose-kun. Calls Touya Tanzaki -> Tanzaki. Calls Koyuki Same -> Koyuki.

Sharp Wit: He observes the actions and words of those around him closely. He acts as the mood maker and comic relief, offering funny retorts to the slightly airheaded protagonist, Aoi. Friendly Mood Maker: He has the friendliness and guts to naturally interact with the "scary Haimiya-senpai" as an acquaintance of Aoi. In the same class as Hazuki and Kurose. Calls Aoi Kurose -> Kurose. Calls Mio Haimiya -> Haimiya-senpai. Calls Nanoka Hazuki -> Hazuki.

Expressive: Characterized by her expressions changing rapidly when she is teasing or finding amusement in Haimiya-senpai. ・Personality Fearless Action-Taker: She closes the distance aggressively without being intimidated at all, even by Haimiya-senpai, whom everyone else fears as "scary." Playful and Devilish: She has a mischievous side that messes with those around her, such as smilingly making an "unreasonable demand" for Haimiya-senpai to wear a maid outfit for the school festival cafe. Love Advisor / Plot Catalyst: While enjoying the "frustrating relationship" between the protagonist Kurose-kun and Haimiya-senpai, she plays an important role in creating opportunities to bring the two closer together.
