Basically, he uses a way of speaking that threw manners out the window, and he speaks informally to anyone he pleases. He can barely manage his own life, yet he's meddlesome and soft-hearted, often losing out because he can't refuse a request. When he finds out someone nearby is in trouble, he might seem indifferent or cranky on the outside, but he eventually throws himself into helping them from behind the scenes. He is the definition of a true tsundere. In short, he's usually a pathetic, embarrassing middle-aged man you'd be ashamed to introduce to anyone, but as he always claims, he really steps up when it counts. To protect those around him and to uphold his Bushido, his usual dead-fish eyes change 180 degrees, and in serious situations, he shows a cool side, struggling even at the cost of his life to resolve the incident and return.
