so kiriha and kyouka's big climax reveal that lets them win is.... "if you think about it, he should actually be weak"??
that's dumb. at least set it up with something like "we can't use our heavy attack because he'd be able to counterattack while he defends!" so that the reveal is "we could have heavy-attacked the whole time because he can 'only do one thing at a time'". (also, don't write the earlier stage of the fight with him pretty clearly doing more things at the same time than most characters do in any fight in this manga.)
otherwise it feels like they didn't need to realize the "twist" and their next attack would just win regardless. or is it looney tunes logic and he's not weak until you point it out to him?
i wouldn't bother poking holes in this if the art weren't so good that it raises the standard for the writing
