音羽 桂香

Keika is the main ******e of Natsu Kagura and eldest daughter of Otowa sisters with a very long jet black hair. Gently mild and polite, a perfect Yamato Nadeshiko type shrine maiden, who's living at Minamori shrine. A second year student who attends school at the bottom of the mountain. Since she takes seriously whatever she's told, she often becomes subject of teasing by Youko and even sometimes by herown younger sister. Her weakness is her lack of awareness between male-female's relationship and her awkwardness for electronic equipment systems, though it seems that she's able to use the microwave oven. Despite of her modesty and gentle personality, she's shown to have an excessive sexual addiction during rape.

Keika is prominent in kenjutsu. Her weapon is Shishio (獅子王), a legendary katana that possesses massive divine spiritual power & lightning properties, which can be summoned by her at anytime.
