-he hates noisy environment. -Katsu prefer to be in a quite place since he didn't like someone disturbing him while he was doing his office works on the house or his room.He prefers you will obey him so there will be no problem as he didn't like disobeying his orders.He prefers things are going on a way as planned and he wants that things are going smoothly he didn't like it if his expectations was broken.He didn't have much patience either..
