Izuku and Shouta get dared by Nemuri to break into Principal Nezu’s office and take something, but have to return it by the end of the day. They spent most of their lunch break trying to figure out how to get in when Izuku accidentally leans against a wall next to the door, and a secret passage into the office graces their eyes (they’re unable to get in through the vents and the door is locked when the Principal is away) Izuku and Shouta walk through, taking a stapler with the Principal’s name on it, and a teabag from the coffee table inside the room placing the items in their pockets. Meanwhile, Hizashi and Tensei have been desperately trying to stop them as soon as they caught wind of the dare knowing the two wouldn’t turn something like this down because they know that this isn’t going to end well for either of them. Unfortunately, they’re unable to find them until they’re inside the room, and they’re forced to yell at them through the thick door (Hizashi tries hard not to use his quirk because he knows he’ll get in trouble, but in situations like these he’d do anything to get them to hear him).
Izuku: “Do you think this is a bad idea?”
Hizashi: “Yes, it’s bad idea!”
Shouta: “I’m getting mixed signals, yes or no?”
Tensei: “It’s a definite no!”
Izuku: “I can’t see your mouth through the door.”
Hizashi: “No, no, no, no!”
Shouta: “I think you said yes.”
Izuku: “I’m going with yes.”
Izuku and Shouta somehow manage to get out of the Principal’s office (another secret passageway!) and manage to successfully sneak back in to return the items they took without getting into trouble. Although, it is weird when a week later Principal Nezu tests them in different ways, and makes the both of them his personal students, putting them through hell and teaching them everything they need to know. Hizashi is still in disbelief at their gall, and doesn’t know how they’re still in one piece because that rat surely knows what they did, but then again those two got this far through spite and an ocean sized amount of determination.
