Sakura Igawa (井河さくら)

Heroine and Asagi's younger sister. A beautiful girl favoring a winning, vigorous attitude. She holds one side of her sister as being brave and gallant. Much like Asagi, she's endowed with the strong ability of the ninja from heredity, yet her strength is still much at an apprentice level. She wants to use her strength for the benefit of justice, aspiring to become an Anti-Demon Ninja member, opposing evil with Asagi. Nevertheless, she keeps her pursuit of knowledge and training hidden from her older sister.

Unlike Asagi, she does not know any ninja arts.
