I would like to see the execution ''Finish'' the opponent the moment the neck gets pierced, just like orochis execution 'Choke on this'
another change that would suit the aesthetics of the execution is for effects to apply to kensei instead of the opponent.

example: with sulfuric sparks, it would be nice to see kensei have the glow instead of the opponent. Having the opponent glow looks like a deity getting worshipped by kensei.
