Agira Ryūdōin

is the father of Jakō, Rokkaku and Genshō.

Background
Sometime in the past, he fought Might Guy and was defeated. After the fight against Guy, he was badly injured and died soon after. His sons tried to take revenge on Might Guy, but in the process, they realised that they misunderstood their father.

Appearance
Agira was a large man, who were seen to wear a long coat and shirt, dark fingerless gloves which extended to his elbow, long pants and common shinobi sandals. He had white shoulder-length hair which parted around his face, not unlike his eldest son, although Agira's fringes were shorter. His face was slightly wrinkled and his forehead was adorned with a tattoo-like arrangement of three tomoe, somewhat resembling the Cursed Seal of Heaven.

Personality
As noted by Guy, Agira was a fine honourable man, evident as he had chosen to fight Guy using his taijutsu instead of his Wooden Puppets and after their battle, when he asked for another try with a satisfied smile. Though Agira himself did not survive to do so, he wished to have a rematch until his death. Guy himself had a great fondness for Agira, noting his respectful ways and, even calling him Agira-chan.

Abilities
Agira was proficient in the Wooden Puppet Manipulation Technique, being able to control and summon a large number of them. His Taijutsu prowess was equally impressive, forcing Guy to open the third of the Eight Gates in order to gain victory.
