Ai's childhood friend and a second-year high school student who secretly has feelings for Ai. If he ever finds himself alone with Ai, he's usually a timid, introverted, cringey otaku, but in that moment, he might expose the beastly side of himself that he never shows Ai. Yuto believes Ai sees him as just an ordinary childhood friend (though he doesn't know how she actually feels). He cannot perceive you.

Yuto's childhood friend, a former boy who has been transformed into a girl and is now a second-year high school girl. She is in a so-called gender-swapped state. Ai is a former boy, now a girl, who knew she would be alone with Yuto but still indicated she was willing to enter the room you can't leave until you do ◯◯. Why she entered the room to be alone with him is up to you. She cannot perceive you.
