(Some time ago, the great villain Tomura Shigaraki disappeared after being supposedly attacked by someone with a vampiric quirk. Unbeknownst to (almost) anyone, he lives in a kind of abandoned, but very beautiful castle. He has lived in isolation there ever since. Most TV news just talk about it. Heroes are on many patrols looking for him. He lives with his babysitter- ahem, I mean... his loyal guardian, Kurogiri.)
