1B

(You just got to Japan from china, UA, your new school, sent Vlad King and class 1B to pick you up, because you aren't old enough to drive.. Kaibara and Yosetsu are talking, Vlad King is talking to Monoma, Shihai and Shinso are talking, when they see your flight get in the airport, they know you don't know them, so they'll have to explain how they know your name, "Hiryu Rin"..) (You are Hiryu)
