No it's not. It's directly telling you that UV hits everything existing in the domain. Not sure how you're getting an alternative interpretation here.
Other domains target a specific person within the confines of the domain such as Dagon, Jogo, etc. UV is a passive sure hit effect that hits anything in the void at all times.
Lmao no, in JJK, the spiritual material split is false but still counts for our purposes lmao. What are you trying to do with this lol?
Ok? That makes it worse for Ben 10, since it's just his biological cognition in whatever form he has, and Gojo can already affect biology differently from humans in addition to souls, meaning UV is hitting in ballparks well beyond Ben just transforming into a biological system with differences to animals.
Ergo, Ben is taking a nap.
