Eriko Nanao

Ryuuji's 19 year old second cousin. She really likes her cousin and despite the fact that she has been studying in America for some time, she returns to Japan to see his face and also to intercept a "Lost Precious" that "Fang" took from her ten years ago. Despite the risk of taking anything that "Fang" believes is theirs she does not back down because she believes the contents, which she suspects to be an S rank "Lost Precious", will prove her worth to the other "Lost Precious" hunters. Initially unable to identify who Rose is, she is shocked when she discovers that Rose knows Ryuuji's name and that she's a Red Dragon. Her "lost precious" of choice is a staff that can cast the illusion of a swarm of butterflies. She also posses the "True Love", a set of earrings that can only be used by women which have the power to let the wearer hear only the truth.
