O-Yakata

was the lord of the castle which was responsible for the execution of the Shichinintai prior to their resurrection by Naraku.

History
The lord had hired the Shichinintai to attack the eastern lands. He had his samurai general speak to the Shichinintai on his behalf. As they made their way against the enemy forces, they were betrayed by the lord's army. He and the neighbouring lords deemed the Shichinintai too dangerous to live and banded their armies together against them. They were eventually captured and beheaded in the northern mountains. The lord of the castle kept Bankotsu's halberd, Banryū, as a trophy of his victory over the mercenary squad.

During the story
When the Shichinintai were resurrected, the lord began conscripting villagers after a warning message was sent to them on behalf of Bankotsu. The lord initially believed that the extra forces were unnecessary, but his subordinate was concerned for his safety. The lord claimed that his possession of Banryū was proof of his feet of killing the Shichinintai and that he would simply kill them again if they have returned.

When the Shichinintai returned to take revenge on him and his castle, Bankotsu came to take back his weapon. After Bankotsu killed his guards and picked up Banryū, O-Yakata remarked that it took three strong men to carry the halberd in, but Bankotsu could lift the weapon with one arm. Frightened of being killed, the lord asked Bankotsu if he would recommence serving him as a mercenary, regardless of the fact that he's a specter. Bankotsu declined the offer with a sigh and cut off the lord's head, getting his revenge for his being beheaded fifteen years ago.

Manga vs. Anime

 * In the anime, it is revealed that the lord is the 1,000th human that Bankotsu has killed with Banryū.
