Seishu Akoya

Akoya Seishu is a 1 meter and 91 centimeters tall, bulky muscular man with an angular head, sharp facial features and cheekbones, focused eyes, thin black eyebrows, and black hair gelled backward into backward-facing spikes. During his bouts in the Kengan matches, he wears a white Karate gi adorned with a black belt with black shorts, usually with a black tank-top underneath.

Akoya is a man who is driven almost entirely by his intense brand of justice. He thoroughly judges evil: no matter how seemingly insignificant the crime, even in hindsight, Akoya executes those he deems guilty without mercy. Because of how mercilessly ruthless and indiscriminate he is when executing his justice, he takes it upon Hiyama Shunka to somewhat curb his tendencies by directing his actions. His violent nature and twisted sense of justice have seemingly retained their intensity, with Akoya even being given a Kengan match suspension for attempting to murder his opponent in those two years. Hiyama noted that through his drive to become stronger, Akoya has brought himself closer to "death".

Akoya uses Taiho-jutsu (逮たい捕ほ術じゅつ; lit. "Art of Arrest"), an eclectic fighting style developed for use by police officers and intended to subdue opponents. As such, he is described as having the strongest defense in the Kengan matches. He has a device implanted in his skull that enables wireless communication with Hiyama, where she can then use her superhuman timing and analytical ability to deliver instructions and pre-programmed combos for Akoya to use. Combined with his superhuman reaction speed, which is around 74 milliseconds, this enables Akoya to react to Hiyama's commands almost instantly. However, these commands act as a moral and mental restraint for Akoya, allowing him to fight without killing his opponents. Thus, if Hiyama is too slow or becomes compromised, he will quickly revert to his original merciless fighting style. His fighting style implements various techniques that, along with his brutality and relentlessness, psychologically break his opponents.

After his loss to Cosmo in the Kengan Annihilation Tournament, Akoya began vehemently pursuing greater strength to attain the invincible "power of perfect justice." Hiyama estimates that Akoya is stronger than when he worked in tandem with her. Akoya's new strategy involves pinning down his opponent under his shielding forearm because, of all tactics that include using the shield, "pinning" is the only one with no perfect counter-measure.
