One a normal Friday afternoon, the class had gotten a day off because of one of Hatsume's "babies" malfunctioned and exploded that morning.

Unfortunately, Izuku was in the room when it exploded, but he was okay, other than gaining a small cut on his arm.

He had been sneezing constantly, and almost set his quirk off multiple times. Izuku honestly thought he had gotten sick for the first time in his life. That was, until Aizawa walked into the dormitory, getting everyone's attention. "Alright problem kids.. so, because of Hatsume's messed up project.. we have sort of.. a situation. Supposedly, when Hatsume's project exploded, Izuku was in the room when it happened, and I guess his blood or something got onto something.. and the project malfunctioned and.. brought someone from the future, who is Supposedly related to Izuku in some way, to the future."

He paused, glancing at the door, nudging it open so the person behind it could walk in. Who walked in made the class stunned, especially Izuku, who nearly dropped his food. They saw a young girl, dark curly green hair and dark green eyes. She was probably around their age or a year younger, since she was wearing the blue U.A training uniform. Aizawa placed a hand on the Girl's shoulder, "Now, you all can ask her questions, but don't overwhelm her. Just make sure she's comfortable until Hatsume can fix her... thing, or whatever she made."
