nice fight.
But kakashi with MS may stil see all of gai's moements begin able to dodge them. He won't be able to use kamui very effectively however due to gai's speed. Specially if he enters the gates.
But kakashi has his dogs which can help him track and hunt guy down. While guy has that turtle which does...the very special thing...um...you know...defense? yeah, IT SUCKS.
Then, we don't know if gai has any nature manipulaion technique or ninjutsu or genjutsu.
But my question is, can MS trace the movemnt of gai 6 gates?
