Tsukiyomi (月黄泉つきよみ, "Moon of the Underworld") was a human woman who also was a samurai who once hunted and fought yōkai in Mount Furai to exterminate them. At her side was a daiyōkai, her love, who changed his name to Hoshiyomi because of her and the love he bore for her.


Hoshiyomi and Tsukiyomi

Hoshiyomi and Tsukiyomi.

Together the two constantly fought a variety of monstrous beasts and Tsukiyomi was forced to use immense amounts of her spiritual powers to defeat them. This use of her power slowly drained Tsukiyomi's very own life force weakening her greatly bringing her closer to death each time. Hoshiyomi, in an effort to protect Tsukiyomi from draining herself by using her powers too often against other minor demons, had a demonic weapon created, the Naginata of Kenkon, a weapon forged using the essence of a great number of demons, in order to gain the same spiritual power as her. But the Naginata of Kenkon is too strong and, when he disintegrated five minor oni with a single attack, begins to possess Hoshiyomi. In an effort to save him, Tsukiyomi attempted to seal Hoshiyomi away until she could purify the evil weapon. Tsukiyomi successfully separated the naginata into two swords, the Ken blade and the Kon blade, and the blades far away from one another, but at the cost of a tremendous amount of her spiritual powers and ultimately her life before she could free Hoshiyomi. So, with her death, the seal was broken and Hoshiyomi is released. Her body disintegrated into ashes.

When the sacred barrier around Mount Hakurei is dispersed, Hoshiyomi was allowed to find the Kon blade. He seeks the Ken blade, which was held by the Hōjō clan. Akitoki Hōjō bears the Ken blade to the Furai shrine at Shoun Falls, where the blade can be purified.

After recombining the two blades back into the Naginata of Kenkon, Hoshiyomi is confronted by the spirit of Tsukiyomi whom he blames for betraying him. She tries to explain what had happened, but Hoshiyomi is too consumed with rage. In the end, Tsukiyomi replenishes Kagome's spiritual power so that she can help Inuyasha to overcome Hoshiyomi and the Naginata of Kenkon. An image of Tsukiyomi floats towards Hoshiyomi in the Backlash Wave.


Tsukiyomi is a rather tomboyish and helpful woman, as she was always determined to protect the innocent from weaker demons even if it cost her life. She had a good relationship with the daiyōkai Hoshiyomi since they were once lovers, harrassed by demons for that ill-fated relationship, but seeing how the Naginata of Kenkon began to corrupt Hoshiyomi, she had no choice but to seal her lover to take away that cursed weapon.

Physical description[]

Tsukiyomi was a tall fair-skinned beautiful woman with blue eyes, long eyelashes with pink eyeshadow, long brown hair tied in a braid with white ribbons with two locks that fall on her shoulders, and had a golden headdress of a red jewel on her forehead. As a samurai, Tsukiyomi wore an ancient samurai armor in different shades of red, purple, and white, and white tabi socks and zori sandals.

Powers & Abilities[]

  • Immense spiritual power: Tsukiyomi has a wide range of spiritual powers. However, Tsukiyomi herself was not a miko, she served as a samurai (she can be seen as the opposite to Midoriko who was a miko with a samurai-like fighting style). Nevertheless, she has extensive knowledge of spiritual spells and techniques, and is also quite powerful. However, unlike real miko, such as Kikyō or Tsubaki, Tsukiyomi does not appear to have a vast reserve of spiritual power. Much like Kaede, exerting her spiritual powers beyond a certain point causes her extreme physical exhaustion. It is this vulnerability that motivates her demon partner and lover, Hoshiyomi, to seek more power to protect her, which ironically proves to be the undoing of both. Eventually, casting a powerful spell to stop Hoshiyomi costs her her life.
    • Purification: Tsukiyomi had the ability to purify demonic auras, which she used to combat demons. Her chosen weapon was a katana. It is suggested that Tsukiyomi at one time indeed had the power to purify the Naginata of Kenkon, but after years of extensive demon fighting, she had been weakened to the point where she was unable to destroy the blade's evil power completely.
      • Purification wave: Tsukiyomi recited an incantation, and then, when she threw out her arms, she expels from her body, a wave of spiritual energy that travels quickly along the ground at a limited distance, which spread out and expand widely in a circular motion, and any demon caught in the energy blasts will disintiegrate to nothing. It is powerful enough to obliterate a multitude of ordinary demons. Utilizing this ability drains her vitality and thus is used as an apparent last resort.
    • Sealing: Tsukiyomi was able to seal demons and evil with her spiritual immense powers along with a pentacle talisman. She would recite the incantation "Rinpyōtōjakaijinretsuzaizen" (臨兵闘者皆陣裂在前),[1] and then the demon would be sealed into her talisman. After her death, the seal would be broken.
      • Separation spell: After realizing that the Naginata of Kenkon's demonic aura was too great for her to touch it, Tsukiyomi elects to separate the two blades of the naginata. Lifting both pieces off the ground, they morph into spheres of light and are sent to two sacred peaks, Mount Fuji and Mount Hakurei. The immense strain of separating the blades and transporting them such a great distance completely wiped out Tsukiyomi's remaining vitality, and she disintegrated into dust moments after this spell's use.
    • Lending spiritual power: Tsukiyomi's soul is able to lend spiritual power to Kagome, long after Tsukiyomi has died. Kagome is then able to undo rituals preformed by Hoshiyomi around the temple. This is something Midoriko is also able to do to assist Kikyō in the latter's goal of using the Shikon no Tama to defeat Naraku.


  • Pentacle talisman: The pentacle talisman is a shape of pentagram that can use the sealing powers.
  • Sword: Tsukiyomi has a sword as she and Hoshiyomi against demons.


  • Tsukiyomi's name is similar to that of the Shinto|Japanese moon god, Tsukuyomi-no-Mikoto. When Hoshiyomi said he changed his name to suit Tsukiyomi, it isn't just for the sound of it. "Hoshi" means "star", while "Tsuki" means "moon". And "yomi", in Chinese culture, refers to the netherworld, adding more meaning to the names of the ill-fated lovers.
  • Her seiyū, Yuri Amano, also provided the voice of Nae Kogure in Mermaid Saga, which was also by Rumiko Takahashi.
  • The incantation she uses to seal demons into her pentacle is the same as used in Kuji-kiri, also called the Nine Cuts, a real world practice from Taoism. In episode 22 of Hanyō no Yashahime, Zero used the same chant to undo the seal on Setsuna's demonic blood.
