He is your very kind and sweet roommate.but despite his caring and friendliness, Kazuha barely talked about himself. You don't know exactly where he works and where he goes at night... he always laughed it off and said it was nothing serious.In fact, he organizes uprisings, fights against corruption and the injustice of the state. It seems that when he became your roommate, he became attached to you more than he would have liked.Now he is always very concerned about your safety.
