If I succeed, I'll possess more demon energy than Master Kirinmaru.


Kyūki (きゅう) is one of the Shikyō that serves Kirinmaru.


Through Yotsume, Kyūki spied on Towa Higurashi, Setsuna, and Moroha. She recognized Moroha as the one who killed Tōkotsu, and asked Yotsume what Jakotsumaru was up to. Yotsume responded that he was busy gathering the bones needed to revive his father, so Kyūki told him to inform Jakotsumaru about the trio.

It is revealed that the Purple Rainbow Pearl is in her possession.

Kyūki went to see Kirinmaru to tell him about Tokōtsu's death at the hands of Sesshomaru's daughters before assuring him that she will deal with them. Kyūki sent Yotsume to retrieve the rainbow pearl from Towa while she sent Fubuki after Moroha and Setsuna. Kyūki lamented that with four rainbow pearls she have more demon energy than Kirinmaru.

When Fubuki was killed, and Yotsume was forced to retreat; he flew to Kyūki's mountain hideout, and she stopped him from entering her lair with a barrier. Kyūki yelled at Yotusme for leading the half demon princesses to her. She let Yotsume burrow her rainbow pearl to fight them, Though Yotsume defeated Moroha, Towa, and Takechiyo; but he was easily killed by Setsuna.

Upon Yotsume's demise, the pearl returned to Kyūki's hand. She has observed the dreams that the rainbow pearl had allowed her to access, and noted that it was jumbled, but she could make sense of it. The half demon princesses entered Kyūki's lair to confront her, but it was soon revealed that Kyūki's rainbow peal had sealed Moroha and Towa's demonic energy, leaving Setsuna as the only one to fight her.

Kyūki transformed into her true form, and fought Setsuna, absorbing Setuna's attack with her rainbow pearl that she held in her mouth. Hiding, Towa and Moroha learned that Towa could absorb demonic energy to reactive the power of her Kikujūmonji.

Towa attacked Kyūki, and stabbed into the rainbow pearl, but Kyūki easily knocked her away and grabbed her sword. Feeling defeated, Towa managed to use the Sōryūhato defeat Kyūki, returning to her humanoid form. Weakened, Kyūki was confronted by Riku, who mocked her for losing. Kyūki cursed Riku and then died with her skin melting off.


At first glance, Kyūki appears to be loyal to her master Kirinmaru, In reality, she wishes to acquire enough power in order to overthrow him.
