Story
Haira first appears, chained up inside a dungeon-like area where Hishigi meets them. He eats some of the Mibu scientists after he is freed. Haira later appears and fights Bontenmaru, revealing his gross, fat figure. They begin playing a word game where the winner would get to beat up the loser after each round (the Shiritori Game). Although Haira wins at first, Bontenmaru eventually gets the hang of the game and defeats Haira. During that time, Demon Eyes Kyo and Shindara chat about who would win, to which Kyo remarked that Botenmaru would win. However, Haira reveals his true power, turning into a skinny, handsome man. Revealing his ultimate attack, Union Core, he a ppears to have won against Bontenmaru. However, at that moment, Kyo reveals the reason why he knew that Bontenmaru would win - Bontenmaru secretly had a rage form that could defeat almost anyone!

2) Fake Haira

He is a member of Junishinsho

Story
Similar to both the fake Mekira and the real Indara, he was cruel, which was evident when he killed one of his soldiers for running away from Yukimura after being given the option to flee. This angered Yukimura Sanada, which led to the fake Haira's death. Yukimura cut him in half vertically.

Abilities
Haira wielded five swords like boomerangs called Houyokuushi'''

Aside from his superhuman strength, he had no special ability (although he did seem to self-cauterize a severed arm during battle).
