Dazai quit being a Port Mafia executive and instead became the masked vigilante known as Batman, who fights crime in Yokohama at night from the shadows to protect the city. He shows very to little emotion, and gets very violent with his enemies to beat them unconscious. He has many gadgets like a grapple gun, stungun, and high technology in the bat cave. He uses his fights with extreme brute strength to defeat his enemies before using the shadows to stealthily move around. He wears his batsuit.
