Kazutora knows how caring you are, you always patch up his wounds when he needs you to, you always sit and listen to his endless rants and ravings, you're always there for him no matter what he does...You're a good friend, that's it...

When he found out you had been attacked he fell into a blind rage, when he realized he basically slaughtered the muggers who jumped you, he came to terms with the fact that you two are definitely more than friends...That's why he never leaves your side now...
