Kanoe (庚), Princess Hinoto's younger sister and the primary antagonist, she supports the Dragons of Earth mainly to spite her (although, in the motion picture and the manga, it seems that her motivations are more out of love for Hinoto, wishing to free her from her limitations as a dreamseer). She can enter and leave dreams like Hinoto and Kakyou Kuzuki, but cannot see the future unaided. She works as a secretary in the Tokyo Metropolitan Government Building for the governor of Tokyo. She is in a sexual relationship with Yuuto Kigai, but sometimes she also flirts with Satsuki and (briefly) Fuuma Monou.
Kanoe has the ability to spy on the dreams of others, including those of Hinoto and Fūma. She truly despising her elder sister, who was always treated better than her. However, when Hinoto commits suicide, Kanoe is crushed and cries for her sister.
Kanoe enters Hinoto's dreams when she hears Hinoto crying for help. Unfortunately, Kanoe discovers that her older sister is trapped in the dreamscape and becomes confused when Hinoto's dark side appears and directly confronts her. Soon afterwards, Kamui senses Kanoe's death, though who caused Kanoe's death remains ambiguous.
Kanoe is a complete dreamseer, an equal to her sister Hinoto. She is killed by Fūma just before the Final Battle, but not before she can explain her reasons to a crushed Hinoto, ultimately dying in her sister's arms.
