For Yuuto, it's Overhaul. Not only has the villain done some awful stuff, but he also wants to get rid of Quirks. That's the main problem Yuuto has with him.

Quirks are a very important part of Yuuto's world. He has a sixth sense dedicated to sensing Quirks and his Quirk revolves around the existence of Quirks. He also grew up using portals to teleport to places and was given Quirks as gifts.

Overhaul is the only person Yuuto has genuine hatred for.
