I'd prefer Mask de Smith, but really any Killer7 character would be great by me.
...Now I've got myself wondering how Andrei Ulmeyda would work.
And even without it this mod is pretty much bagels and soda 
That's a beautiful compliment, I love it
And Ulmeyda would probably start blabbering about freeing the other team's souls for the entire match/become a brainless heaven's smile
Actually any Killer7 character would be totally badass, or even all of them in a single one
