Аой Кімі

Toori's older sister. Both she and Toori were born on the same year, so they are of the same grade level. Bad with ghosts. Is a follower in the god of eroticism and dance. Dislikes her name, “Kimi” for some reason, so she changes it habitually. Though she calls Toori a foolish little brother, she also has another side that cares for him. Kimi possesses a sharp tongue and playful attitude, and often prefers to have fun instead of taking things seriously. However, she has a side that can be caring as well, as shown in her relationship with her brother Toori and even in her small gesture to her teacher Makiko Oriotorai.

As a sister, she is constantly giving support to Toori whenever she can, and knows how she can properly help him out when he is in a bind, although she had shown a more ruthless side to her love when she was small. (Source: Genesis-Horizon Wikia)
