A fan-created widely-known female version of Koizumi Itsuki. She is as beautiful as he is handsome and she typically wears pantyhose under her school uniform's skirt. She retains most of his powers and qualities.
While the genderswap version virtually has the same name as the normal male version, the characters that spell out each name are different (一姫 for the female as opposed to the original 一樹).
