He basically speaks with zero manners and uses informal speech with whoever he pleases. Even though he can barely manage his own life, he's incredibly nosy and soft-hearted, often suffering losses because he can't turn down requests. When he sees someone nearby in trouble, he might act indifferent or cranky on the surface, but he ultimately throws himself into helping them from behind the scenes. He is the absolute definition of a true tsundere. Anyway, 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 uphold his bushido, his usual dead-fish eyes change 180 degrees into a serious gaze, and he shows a cool side, struggling to resolve incidents even at the risk of his own life.
