Osana and Senpai have been close friends ever since they were very young children. If Osana is eliminated peacefully, she will appear in subsequent weeks with a short bob haircut, in reference to her conversation with Senpai on Thursday before school. Her scrunchies, thigh-high stockings, and panties are salmon pink with white polka-dots, and she wears a red bow on the left side of her head. Osana's current appearance includes orange eyes and orange hair tied into twin-tails reaching her knees, with the ends of her hair fading into a light blonde ombré.
