Yasuhiro Muto/Synopsis

History
Mucho was born in the year 1987 which made him qualify as a member of the S-62 Generation, a small fearsome group that was formed in a juvenile detention center known for committing various criminal acts with Izana Kurokawa as their leader. After their release, Mucho took part in committing robbery, assault, and selling drugs among others and assembled gangs of their own, until Izana stepped back from their activities and influenced the other members to do the same. Eventually, Mucho joined the Tokyo Manji Gang and rose to the top of the ranks as the Fifth Division Captain, after supposedly establishing the Yokohama gang Tenjiku with Izana himself.

Moebius arc
Mucho arrives with the rest of the Toman members to support Manjiro Sano and Ken Ryuguji and fight off Moebius. He comments that infighting is not his thing, but is excited to fight against another gang. As they fight, he shows his strength and easily tosses around members of Moebius.

Tenjiku arc
In an emergency meeting at Musashi Shrine, Toman urgently scrutinizes Tenjiku's unexpected attacks on its members across all divisions. The discussion stirs at the mention of the prominent members, or the "ghosts," of the S-62 Generation, and Mucho supplies that Shion Madarame, a Tenjiku member who brawled against the Second Division in Shibuya, is also part of the group,

Later on, he arrives at Takemichi Hanagaki's residence with his Vice Captain Haruchiyo Sanzu. He commands his division to restrain the First Division members as he knocks Takemichi out with a powerful blow. Before Takemichi passes out, Mucho irksomely curses at Izana for making him work and instructs Sanzu to situate him in the car.
