Shinku Yūhi

Kurenai Yūhi's father was a Konoha shinobi.

Background
During the Nine-Tails' Attack on Konoha, Kurenai's father was seen placing the young shinobi inside a barrier, informing them that they were to stay out of the fight against the Nine-Tailed Demon Fox, to which Kurenai voiced her discontentment with. He told his daughter that she was a shinobi and may or may not live a long life, and requested of her that she live long enough to have a child that she could pass the Will of Fire on to.

Trivia

 * Kurenai inherited her distinctive ringed eyes from her father.
