Kaguya is a princess who was raised by an elderly couple, she was apparently found by her foster father as an infant in a bamboo stalk.
She possesses mysterious abilities, including the power to heal wounds with a light touch. Kaguya had many suitors, but they were all slaughtered and it was believed she was a Horror. In truth, Kaguya's foster parents ended up becoming hosts for Horrors due to their greed, demanding expensive and rare treasures as gifts from suitors in Kaguya's name. The Makai warrior Raikou, however, sought to learn the truth and ended up befriending her. Once Raikou slays the Horrors, Kaguya decides to return to the moon, having lost the only two people who compelled her to remain on Earth. Kaguya returns once more to Earth for unexplained reasons when the moon turns crimson due to Ashiya Dōman and Priest Dōma's schemes. Upon reuniting with Raikou, it is revealed that Kaguya is a human-shaped Madōgu, created by an ancestor of the Abe clan to seal Rudra. She has forgotten the full extent of her power, but is slowly remembering her abilities piece by piece. She displays her aforementioned healing abilities and the power to create a magical barrier, though Haruaki mentions she has the potential to be far more powerful. She's shown to recover almost all of her power during a ritual performed by Abe no Haruaki. Later, after receiving Michinaga's magic book, she is able to remember all 12 lines of Rudra's sealing incantation. After Rudra is sealed, Kaguya returns to the moon once more, promising to watch over her friends and observe humanity's progress.
- Unlike most of the cast, Kaguya is based on an old Japanese tale rather than a historical figure.
- Is shown to possess feelings for Raikou.
- As human-like Madōgu, Kaguya is similar to Agō from Ryūga-verse.
