Keisuke Baji was the First Division Captain of the Tokyo Manji Gang and one of its founding members. Baji has a wild personality. He loves the thrill of adrenaline and Mikey himself says that he would punch someone out on the street for no apparent reason, only because he feels like it. In combat, he is never without his trademark grin. Baji is fiercely loyal to Toman. He is willing to cast himself as the villain in his friends and comrades' eyes in order to protect them. In the end, he is even willing to sacrifice himself to ensure that Toman does not lose its way. He is also a very perceptive individual, seeing through who the true villains who threaten Toman are. He is the only one, aside from Takemichi, who is a time traveler, who does so, revealing his sharp intellect. Baji's acting skills are remarkable. He is able to fool both friend and foe into thinking he truly defects to Valhalla. Even the most perceptive ones who suspect him at first get tricked into thinking he really cut ties with Toman.
