For a coward, Kato sure is a badass. Beating up that heavyweight boxer who's out for his ass while he was taking a dump was already cool enough but he even locked the door behind him as a pre-condition!
Yeah, I was pretty sure that Kato was freaking out ... but the he comes in and kicks that kids ass ... Anyways I feel like Kei and Kato traded places, and now Kei is some cowardly weakling while Kato is some heroic strong guy.
