Ruby Ninja Princess Honoka

A martial artist from the Setsuga clan, which fights evil from the shadows. The young prodigy gained notoriety for her skill with the short sword despite her age. She would appear out of nowhere to cut down evil with her lightning-quick blade and was viewed as a hero by the good people she protected. However, when she discovered the evil born of the Setsuga clan's deeds and came face-to-face with her own naivety, she decided to flee the valley with her taciturn bodyguard. That was the start of her journey to punish evil and learn self-control.
