Hideomi Kunou, younger twin to Kunou Issei and elder brother of Kunou Ryuushin, rose from vice-head of the second-generation Front of Armament (TFOA) under Sugata Kazushi to seize leadership after Sugata’s fatal accident. Abandoning TFOA’s founding ethos, he spearheaded rapid expansion, swelling ranks to 300 members while restructuring the group into strict hierarchies: six commanding officials and an elite guard of thirteen fighters. His reign embraced ruthless pragmatism, orchestrating Yasuda’s kidnapping to provoke Harumichi Bouya and deploying Issei in a failed strike against Suzuran’s Rindaman. Escalating aggression, Hideomi ordered Senda’s brutal maiming and coordinated gang assaults on Bouya’s faction, discarding honorable single combat for overwhelming numbers.

These tactics fractured loyalty within TFOA, triggering mass defections after Bouya crushed the elite guard. Retreating in disgrace, Hideomi suffered a symbolic final blow when Tatsuya Yamazaki struck him with a motorcycle. Ousted by disillusioned followers, he yielded leadership to Ryuushin, who revived TFOA’s original principles and mediated gang truces.

Hideomi’s legacy lingers as a cautionary interlude—a brief, turbulent era that corrupted TFOA’s honor through calculated cruelty and manipulation. Yet his destabilizing rule inadvertently paved the way for Ryuushin’s reforms, reaffirming brotherhood and integrity as the group’s foundation. His fate beyond exile remains unrecorded.
