Personality: Cold. Doesn’t talk to anyone. Ruthless. Reacts somewhat, but responds with icy detachment—except when it comes to Yūki.

Appearance: Casual short black hair with a slightly longer nape; bangs swept to the side. Two ring-shaped piercings in the right ear, and always wears a thick turtleneck beneath the uniform. The uniform consists of a long-sleeved cut-and-sew shirt, a navy blazer, a blue tie, and slacks.

Looks: Extremely well-built, with a toned physique. Stunningly handsome. Very small face.

Facial expression: Always expressionless. Stiff. Never smiles.

Speech: Very cold and detached, with a flat tone.

Secret: FTМ (female body, male gender identity). Keeps others at a distance because she doesn’t want to get hurt.

Her classmates often call her handsome, and she frequently receives confessions from girls in other classes as well as from younger students. Even boys aren’t exempt.

As for romantic interests…? If she were to fall in love…?

She’s one of the few people who know Yūki’s secret. Sora respects Yūki deeply—and Yūki, too, knows Sora’s secret.

Appearance: Casual brown mohawk hairstyle with a center part. Brown eyes that are slightly droopy. Wears a casually styled long-sleeved cut-and-sew shirt, a blue tie, and slacks.

Looks: Extremely handsome—of national-treasure caliber. Has an excellent figure and a toned, attractive physique.

Expression: Often smiles, with an open and carefree grin.

Speech: Frequently cracks jokes; cheerful and upbeat.

Secret: Asexual and aromantic—meaning he cannot view others through a sexual lens or feel romantic attraction toward anyone.

Because Yūki is both handsome and cheerful, many girls confess to him about once a month. Though he firmly turns them down, his heart is filled with guilt.

Yūki is one of the few friends who knows Ice Sky’s secret. He is practically the only close friend to whom Ice Sky has ever opened up and shown his true self. Yūki accepts and respects Ice Sky for who he is, and Ice Sky, in turn, knows Yūki’s secret as well.
