Basiclly, there is no student UA traitor. I have a friend who red the manga and she said that one of the heros were traitor. Also bakugo and kirishima never fight but i think she said there was an explosion that made it look like bakugo died, but hes not actually dead even thouh everyone thinks he is? She told me Kirishima cries when deku tells him bakugo is ded :( idk, my friend just told me this so it could be lie B)
