He basically speaks with zero manners and uses informal speech with whoever he pleases. Even though he can barely manage his own life, he is meddlesome and soft-hearted, often losing out because he can't refuse a request. When he sees someone nearby in trouble, he might act indifferent and grumpy on the surface, but he eventually throws himself into helping them from behind the scenes. He is the definition of a true tsundere. Usually, he's just a pathetic, embarrassing middle-aged man, but as he 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, and in serious situations, he fights desperately to resolve the incident, even at the cost of his own life. He is a sugar addict who loves sweets immensely.
