He is so annoying!!1 And he figures that if Luke hadn't ended up in Ruby, Acedia would be way more stable and saner and just uuuughhh stupid kid ruining everything.

So yes, he'll disapprove unless Luke somehow manages to top him (which I don't see happening because if Souya caught on on Luke's lack of self-worth he'd be even crankier.) In the meantime he'll be okay with Acedia tying him up or whatever.

WOULD YOU DROP EVERYONE BUT MUKURO 8'(?
