Hoshiyomi

Hoshiyomi ( 星黄泉 underworld of stars), a humanoid ninja yōkai, was once a daiyōkai who fought for good and justice alongside his human love, Tsukiyomi. A powerful pair, Hoshiyomi eventually employed Kaijinbo, Totosai’s evil former apprentice, to craft a weapon for him, after Tsukiyomi began to show extreme signs of fatigue from their battle efforts. With 222 demons Kaijinbo finally crafted the ‘’Naginata of Kenkon’’ (trans. “Halberd of Heaven and Earth”), a powerful sword with a stave in the middle of two separate, yet equally balancing powerful blades. After Hoshiyomi received his prize Tsukiyomi no longer had to fight their common foes, but he struggled with the evil from the sword that was possessing him. Tsukiyomi eventually sealed Hoshiyomi within a pentagram with the intent of destroying the naginata; however, her plans went awry as fatigue overtook her and she died before she could both destroy the naginata or release Hoshiyomi. Decades later, Hoshiyomi was freed and eventually reacquired both blades (one of which Akitoki Hojo had in his possession to guard), waging war on all of humanity for “its betrayal.” After creating a black hole-like vortex, Inuyasha and Kagome are eventually able to defeat him with the combined power of Inuyasha’s Backlash Wave, Kagome’s sacred arrow, and a little spiritual interference from Tsukiyomi’s soul; the Naginata of Kenkon is destroyed along with him. In addition, just before Hoshiyomi’s death, he realizes Tsukiyomi’s true intent (having begrudged her for sealing him away) of her last actions, forgives her, and, upon his death, is reunited with her. Hoshiyomi appears in episodes 137-140 of the anime in "An Ancestor Named Kagome", "Mountain of Demons: Survival of the Duo", "The Great Duel at Shoun Falls", and" Eternal Love, the Naginata of Kenkon."
