Retsu

The third generation of the Higuma Gang, Retsu is Kazuma's old friend. He gave Kazuma pudding as an apology for his men because they almost raped Fumino without realizing that she is Kazuma's wife. When he invites Fumino to his home so that he can apologize again, he tells her that she is stupid for believing that he is a good person. Kazuma then busts into the scene, kicking Retsu in the face and causing his nose to bleed. It is revealed he was just joking around with Fumino and is actually a nice person. He is known as "The Pudding Person". From Wikipedia
