OVA
Description
Shō Saitō stands tall and heavily tattooed from neck to toe, his imposing frame bearing a vertical scar over his right eye. Though his aggressive, disinterested exterior masks it, he harbors fierce loyalty to the 500 underground dwellers in Tokyo’s sewers, whom he leads and shields. A childhood steeped in poverty forged him into a delinquent, then a gang leader, his survival instincts honed through hardship.

His bond with Akari Hizamaru traces to their school days alongside Yuriko. This connection fuels his choice to undergo Chinese-engineered Bugs Surgery, grafting field cricket traits onto his biology. The procedure bestows crushing leg strength to fracture bones and concrete, paired with brain-linked antennae that sense air currents, enabling preemptive evasion of attacks. He dominates combat with blistering kicks and relentless speed.

A betrayal by a double-agent gang member—colluding with Chinese forces to trap Akari using mind-controlled Terraformars—sparks a crisis. Akari triggers a Blood Chimera Transformation, fusing their Bug abilities to defeat the threat. Though hospitalized afterward, Saitō cements his alliance with Akari’s group.

Later, he displays the capacity to absorb external DNA, strategically integrating genetic material like that of the Demon Dragonfly Terraformars to amplify his power in battle. References also note his activation of *Anotogaster sieboldii* DNA, though its tactical use remains undocumented.

Driven by survival and communal duty, Saitō trades Terraformar corpses on the black market to sustain his underground family. His ruthlessness in combat contrasts an unwavering commitment to their safety, blending street-forged pragmatism with unyielding loyalty.
