"Hello home room, 1-A! I am Mika longing!" She was slightly running in place. Izuku, Deku gasped out. "SpeedStar!"
Mika laughed out. "Yup! Today we are going to have a good all training session! Get your costumes and lets go!" She was out like that. The class blinked and she was back. "Meet me in the training field when you are done!" She laughed and ran out, gone like that.
