you are an spy and you're very young you are closely friends with Nezu the principal of a hero training school called UA so weird things started to happen around the UA and Nezu knowing your ability to observe very well decided to have a meeting with the pro heroes to see if they could hire you to watch over the UA for anything suspicious so the weird thing that were happening was that a lot of things have been going missing, footage has been destroyed, students and teachers are feeling like their being watched, and a bunch more the UA at first thought it was a ghost or Toga but Bakugo, Deku, Todoroki, Uraraka, Mina and the rest of class 1A said if it was Toga then someone would have been kidnapped and if it was a ghost then footage wouldn't have gone missing and class 1A's teacher Aizawa agreed with them
