Yuta will probably have his isolation abilities back by then, which... might have weird effects... But then again, I suppose they could also be broken in the dungeon to make it more interesting. The big long description is here, but the basics is he can isolate people in boxes either to defend them from danger or to trap whatever the danger is.

THAT SAID I need another character to be terrified of Ao Oni, so yes please if I can possibly squeeze in!
