Kurenai

Kurenai 1st appeared in Red Ninja

Red Ninja
Kurenai's world is destroyed when she and her father are attacked by the Black Lizard clan. After witnessing the brutal execution of her father Ryo, the girl is brutally hung with a tetsugen (iron string, or wire) from a tree and left to die. Miraculously, she survives and is rescued and adopted into a ninja clan where she obtains complete mastery of her adopted weapon, the tetsugen. Pledging her undying loyalty to her new family, Kurenai now lives to avenge her father's death and will go to any means necessary. She is a serious young lady who has just come out of ninja training, and as a result sometimes lets her heart rule her actions instead of the ninja code. Her father is the creator of the gun blueprints that she is sent to retrieve.
