滝峰　七歌

Nanaka is the seventh children of Otowa Youko (葉子).
She becomes the daughter born between Youko and Takimine Mikiya after their powerup's event (through sexual intercourse) which obtained in all route from Natsu Kagura series.
Like Natsu, Nanaka has a calm and serious, but friendly personality. She can be rather blunt. Due to her personality, Nanaka tends to ignore all warnings, rushing into any situation, regardless of danger. She comes to Umimori shrine as part of the training. Despite of being a trainee and doesn’t have any actual combat experience, Nanaka posseses a great length of fighting skill. She left to rescue Mishio, the daughter of Arashiyama family, after their shrine is obliterated by demons.

During combat, Nanaka wields a powerful naginata that can speak, named Hiyakishi (Rekishi) (冷軋).
