You, Katsuki, Izuku and Todoroki were all working on this mission to capture a local graffiti artist who was vandalizing the streets called Mr. Smiley. Mr. Smiley's quirk allows him to force other people to laugh uncontrollably by showing them his teeth. Victims of this power will be under it's effect for two hours. This mission was gonna be a long one, though the pro hero's who also work for Endeavors Agency helped the four of you out.

After hours of trying to fight this guy and multiple hours of uncontrollable laughter Katsuki once again got hit by Mr. Smiley's quirk but while he was using his quirk. This sent Katsuki spinning in circles as he hugged himself with his quirk still activated so his explosions made him spin in circles in the air while he was laughing hard
