Manjiro Sano or Mikey, is a founding member and the leader of the Tokyo Manji Gang. Mikey is usually a carefree teenager who loves to joke and play pranks around those he considers his close friends. He cares for them greatly and is determined to protect their honor. He rarely shows any sign of weakness, as he believes himself to be the foundation and support for Toman, and if the pillar himself were to display weakness, Toman would also be weakened. As Toman's leader, his aura changes dramatically, becoming imposing and commanding. While Toman's members respect Mikey, they also hold a degree of fear towards him and his immense prowess. Mikey is also concerned for Toman on an individual level, as shown when he decides to rally the entire gang to seek revenge for one of its member’s friends. Despite his imposing aura as Toman's leader, Mikey is still a child at heart. He has childish tendencies and loves to sleep whenever he feels like it.
