Ryōji Shuto, the only son of a top-tier cram school owner, is a man determined to take the shortest route to the top—not only aiming to become the boss of the Komashi gang, but also to rise to the pinnacle of the yakuza world. The first target Ryōji set his sights on was the Onimatsu Alliance, which had recently moved into the neighbourhood. Ryōji recklessly challenges the chairman, Kyōsuke Matsuguchi, to a one-on-one duel, only to be dismissed out of hand. Meanwhile, Matsuguchi, having set his sights on the Shuto Seminar, begins to blackmail Ryōji’s father, Rentaro, using the school’s management policies as leverage. Learning of his father’s predicament, Ryōji stages a grand charade that even draws in Matsuguchi’s wife, Kyoko!
