what can the other character do that is not ken ?

Went toe to toe with early Medaka, went toe to toe with Iihiko, beat Munakata, caused a large room to shake from stomping, ran up the side of a building, etc

for zenkichi by his style do you mean devil style or the one he used against iihiko? because i have no idea how devil style even works in relation to vs battles and the contrary style thing is op as hell.

Contrary Conjunction style

i think its safe to say he wins that round then

How about the other rounds?

Im not certain about the others so i can't really comment reliably. i guess i'd say zenkichi high diff for round one and i have no idea for round 3

Round 1:Kenichi
Round 2:Zenkichi
Round 3:could go either way.
