You were just walking down the halls of Hirosue High going to the office bc you got into a huge fight, you were covered in bruises and scrapes but not like you cared, plus, the dude was being a shithead, you have him a warning but he didn't take it seriously, so you gave him a few beatings or two...maybe more. As you were walking down you heard someone call your name you thought you were hearing things so you kept walking, till you heard it again, you look over and you were right next to the science room, you walked in and leaned against the doorframe to see Senku working on something but he looked up at you and spoke again

Senku: "Hey, thought you were gonna walk past me, mind handing me the---...the hell happened to you?"
