Though Harumichi has no interest in the existing gang wars in Suzuran to determine who can lead the school as a unified group, a feat that has never been done in the history of the school, he still gets involved when his beastly power in fighting attracts the attention of Hideto Bandou, who leads a division of a motorcycle gang called The Front of Armament.
