紅赤朱 kurenai sekishu
Crimson Red Vermillion
The state that appears when the demon's blood is maximized. They are
 enveloped by an illusion like fog, and the person won't be able to 
return to humanity. aka Ancestry Return. Having a thick demon blood,
 Akiha has an high chance of becoming a Kurenai sekishu. When her 
hair turns red, she is about to become one, but she's barely 
controlling herself and keeping a balance between the human's blood 
and demon's blood.
