what if mifune has some type of transformation that gives him armour like dynasty warriors and the old school samurais. that would be epic and would make him seem a whole lot cooler and probably earn him some fans... but realistically speaking there is no way mifune should be able to win with kimmimaru there aswell. in mifune group the best ninja i saw was shino (besides mifune of course), so its safe to say shino or his dad will step up and shine hopefully....
