The next day after the exam as Mr. Aizawa said, Mineta was gone. Replaced by another student from the general studies course, his name Hitoshi Shinso. Izuku was glad for the change as it meant he didn't have to be in the same school as that pervert. They had hero class that day and Izuku was excited to say the least, even more since it was taught by All Might himself. Izuku couldn't wait until he learned he was going against his childhood best friend turned bully, Bakugo. (Izuku's costume consisted of a deep purple dress and shoes, the dress had light purple highlights, the dress's skirt was short, light purple stockings and gloves, last of all was the ribbon/bow he wore around the bottom waist.) Luckly for Izuku, Izuku had a plan. In which was they would use Ochaco's quirk to get into the top floor and look for the bomb from the top floor down. Izuku knew only Tenya would be with the bomb since Bakugo would go after him and that consisted of going to the entrance of the building where Bakugo will think they'll be, so Izuku wasn't worried about him. Then when they find the bomb Izuku would distract Tenya by throwing poised apples at him while Ochaco secretly floated to the bomb, getting there via the ceiling so Tenya wouldn't see her. The plan worked with Bakugo being completely unaware of what was going on until it was too late.
The rest of the battles went smoothly, even the new guys who used his quirk to make one opponent attack another while staying safe in the bomb room which Momo sealed using her quirk. After that nothing interesting happened exapted Ochaco's jealousy of Izuku grew (due to the fact Izuku thought up the plan which won them their battle) which she fought with all her will power but it still grew. Unfortunately it grew even bigger the next day, when they had the class election for president and vice president and Izuku won the former. Unaware that Izuku didn't want the win, because he didn't feel up to the job. Later that day, there was an alarm which sent all the students running for the exits which resulted in them all getting cramped together. Then Izuku noticed that it was the paparazzi that caused the alarm, so he had Ochaco flout Tenya above the crowd. Unfortunately he slammed into a wall but that didn't stop him from doing his task, which was saying "Everyone, don't panic. It's just the paparazzi, please calm down." Which he did, this got everyone to settle down and inspired Izuku to give his position of president to Tenya. Which he did, unaware of how Ochaco feelings of jealousy grew from the act of him giving the idea that stopped the mass panic.
