Ay and Minato's mystery cost 20 chakra, both can be used round 2, Ay also tags a whole line of enemies with his mystery+double standards and clear debuffs from jinpachi. Minato dodges so they're not gonna target him, Ay has super armor, fire main is vulnerable. Jinpachi ignites together with massive damage usually kill healer round 2, and even if 1 healer survives they won't heal anything.

Very high combo even with King of Hell, Dog of Hell works as well.
