He hits people when they suddenly appear from behind like a defense mechanism. B/c the long haired guy was always doing sneak attacks against him from behind in order to try and make him stronger i guess you could say. Shissa said he wears the eye patch because Hokuto elbowed him in the eye in the beginning..I think there's something else wrong with his eye though that hasn't been said yet. The long haired guy is Hokuto's half brother from their Yakuza father and the blonde guy with him i think is just like his follower. They're not really related
What the heck is going on? I can't understand anything. Why is he hitting people? How does he know those other two brothers? What's with the eye? I'm so confused!! *crying*
