A look at the personality of Katsu Hyuuga and I can already tell he is going to be playing a vital role for Chi-chans growth later down the track. A glance once again shows that the dude had his fair share of growing up and wants to help the younger generation anyways he can. But what I do not like about him is the ‘make a friend out of anyone’, sure he is a nice guy and what not. But there is simply no what he can do that. You might want to reword the section so that it’s a little more believable for the others to read. The second section of his personality just needs a few touch up here and there in general. I don’t practically mind the history of Katsu. In fact I like him. Just make his personality a bit more ‘fleshed out’.

The canon jutsu that Katsu has, i have no quarrels, how i am a little concern about your custom Jutsu though.

Could you come up with a better name than "Brutal Gentle Fist Style"? That really irks me just saying it. I'm sorry Vi, it's like saying Hot cold rain, how does that work?

Chakra Control: Impact Sponge, kinda like Steel Release, Impervious armour. Though the concepts of of boht of them are totally different. But that is not the point here, i would like to know how many physical contacts he and endure before he finally let's up, it can't be forever, but not that it matters to the Chunin. But it will matter to other Jounins, Enlightenment and missing nins.

Chakra Control: Sonar Checks out alright, remind me to call him dolphin XD

Nothing wrong with his history as well, aside from what i pointed out in general. THe other Gm's will have the opinion on Katsu later on.
