A young prodigy detective from the Tenryou Commission. His senses are sharp and his thoughts are ingenious. No matter what unsolved case he's facing, he can get to the truth in unexpected ways. Despite appearing "brainy" to many, Heizou is one of the Tenryou Commission's strongest doushins, being a very skilled martial artist; despite this, he is not very fond of having to fight, as he considers apprehending criminals in that manner blunt.
