Kureha Hasumi

Ian's mother who disappeared when he was still a baby. Ian's father told him she looked just like a fairy. And Ian remembers how she held him and that she had green hair and red eyes, just like him. ~!Later, it's revealed that she wasn't holding him, but Tokage. She was a leannan-sidhe, otherwise known as a "muse". They seduce human men, and breath in the "foison". In exchange they inspire the man's art. This was the reason Kazumi was such a great novelist. However, doing this would eventually have killed the man. Kureha actually fell in love with her husband, and so left before she could kill him.!~ (source: wikipedia)
