Hiruma Masami

Kaikoga Masami was a member of the Moth Clan who married into the Crab Clan as Hiruma Masami.

Moth Clan
Masami, born a member of the Kaikoga family of the Moth Clan, a Minor Clan focused on studying the nature of Yume-dō, the Realm of Dreams, was trained as a shugenja.

Crab Clan
Masami married into the Hiruma family and assisted in the care of the temple located within Shiro Hiruma.

Death
In 716, an oni referred to as The Maw raised an army of unprecedented size and power. 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. 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, rather than become corrupted by Atsumari no Oni. The ritual was insufficient to save the castle, but it greatly reduced the power of Atsumari no Oni and saved the souls of hundreds of Hiruma samurai. Incensed at being thwarted, the oni turned its rage on Masami. She sacrificed her life to send the oni back to Jigoku and herself to Yume-dō.

Ritual
Masami knew she could not make the outcome of her ritual permanent, for that would effectively halt the Karmic Wheel] for the souls in question. Instead, she used three keys to enact the ritual, and these same three keys could, in turn, also unravel the ritual and end its effects. The keys were: the final passage of Masami's ritual, spoken aloud; the [[wakizashi (TCG)|wakizashi of the Hiruma family daimyō; and finally Masami's name, which she surrendered to empower the ritual. In 1123 the mahō-tsukai Kitsu Sokori attempted the return of the oni, but a group of samurai avoided it.
