神田裕之
When Gamma and Yasushi Kanda began to have serious problems with each other, he helped organize a match between them where the loser would be kicked out of Real Hazard. Even though Kanda lost, Gamma ended up being the one ousted from the unit, after Kenichiro Arai joined the group's ranks and assisted them in beating down Gamma. Yamato then took over Gamma's role as leader.
