So as we see, Sinner pretty much is the strongest Demon in NNT, and we're about to see him fight the whole Seven Deadly Sins+Mael/Elizabeth so anyone knows what HST Character he can beat.
Round 1) Bleach
Round 2) Naruto
Round 3) One Piece
Round 4) All together.
I'll try to bump this with every new chapter comes out for Sinner.
