I just hope Kaede Misu will be obtainable in normal gacha, than Event. Or maybe in future stages. She is so cool. But by that destiny, my Event Gacha Ticket decided choose a teacher. Please, I beg Kaede Misu was available as one of four next stage 4 bosses. I'll swear I'll be nicer for girls TT.TT.
