I'm Babysitting For Villains?!?!

After taking a seemingly ordinary babysitting job, quirkless Izuku Midoriya unexpectedly finds himself becoming part of the strange but loving Yama-Zawa family, growing close to traumatized siblings Eri and Hitoshi while slowly uncovering unsettling secrets surrounding their parents. When a villain attack on UA leaves friends and teachers injured and reveals the existence of a terrifying force operating in the shadows, Izuku's obsession with information and his own shady past drag him deeper into the criminal underworld. As bonds strengthen and feelings begin to develop, Izuku finds himself balancing family, secrets, and dangerous investigations to keep those around him safe, all while remaining blissfully unaware of one crucial fact: the people he's come to love are some of Japan's most infamous villains. That is, of course, until the truth is forced into the light.
