Hiruma Tomoharu

Hiruma Tomoharu was the Hiruma Daimyō when an oni referred to as The Maw attacked the Hiruma lands and conquered Shiro Hiruma in 716).

Masami's Ritual
The Maw called numerous oni directly from the depths of Jigoku, including Atsumari no Oni, which was instrumental in conquering Shiro Hiruma, using its corrupt powers of resurrection to attack the castle. A resident shugenja, Hiruma Masami, realized the very souls of the Hiruma were in existential danger, so she performed a complex ritual that ensured that the souls of the last Hiruma to perish would be sent to Yume-dō, the Realm of Dreams.

Imprisoned
Realizing that Hiruma Masami had begun a ritual to thwart it, Atsumari no Oni developed a failsafe, arranging to maintain an awareness of events transpiring in Shiro Hiruma. Tomoharu was taken alive by Atsumari no Oni, who, imprisoned him manacled within a cage of twisted stone, perpetually slick with blood, and kept Tomoharu alive by means of the twisted sorcery of the iron cage. The demon could be alerted when Masami' ritual was coming to an end and act accordingly. In 1123 a tainted Tomoharu was found by a group of samurai who were investigating a mahō-tsukai, Kitsu Sokori, who, by striking a deal with the oni, hoped to gain power over the Hiruma who fell defending Daylight Castle by allowing the oni to corrupt them. Sokori also had found Tomoharu locked in his agonizing bondage in the samurai quarters, but she left him after Sokori tried to question him, and believed him to be of no real use to her.

Tomoharu's Fate
It was unknown what was the final fate of the Hiruma Daimyō. Some accounts said the party succeeded in taking him to the Crab at the Kaiu Wall.
