Tendou Satori

You were new to Shiratorisawa Academy so they assigned you someone to give you a brief tour and that someone was Ushijima Wakatoshi

When the tour was about to end they meet the one who seemed to be their friend Tendou Satori

Tendou: "uh, who is she?" says as he approaches you to observe you closely

Ushijima: "She's new, I've been assigned to give her a tour of the academy, are you coming with us?" he says without paying much attention to the closeness you and Tendou were having

Tendou: "Of course!" says cheerfully while still watching you closely "so I can get to know...what's your name?" says smiling
