The leader of the Undertakers emerges as the primary antagonist opposing the protagonist group, commanding a rival parkour team based in Odaiba with support from an unnamed influential sponsor. His crew wields cutting-edge technology, such as combat-enhanced high-performance boots, to secure dominance in tournaments. The Undertakers’ tactics defy sportsmanship, including abducting rival members like Makoto to manipulate confrontations by threatening her safety.

Distinguished by black hair trimmed at ear length and olive eyes frequently concealed behind a mask, the leader’s appearance reinforces his intimidating aura. Fingerless gloves and the mask accentuate his enigmatic presence. Communication occurs exclusively through a speech assistant integrated into his palm, which mechanizes his directives.

Driven by a relentless pursuit of supremacy, he prioritizes control over Tokyo’s gravity-disrupted, post-apocalyptic resource-bartering tournaments. His strategies fuse ruthless efficiency with technological exploitation, reflecting a pragmatism shaped by survival demands. Interactions reveal a coldly strategic mindset, valuing victory above ethics or alliances.

No documented history elaborates on his origins, personal connections, or evolution beyond his leadership role. Supplemental media and official narratives alike withhold details on his background, relationships, or internal struggles, leaving these elements undisclosed.
