Himiko adheres closely to Kaon and is one of Mika039s many lovers although the relationship is not romantic rather Himiko is Mika039s subordinate in all things with Mika using her as she sees fit. Himiko has even mentioned that her name was 039assigned039 to her by Mika. She is based off of the character Himeko Kurusugawa from Kannazuki no Miko and has been said to be Himeko039s reincarnation. She certainly seems to display Himeko039s lack of selfconfidence and strong emotional bond with Chikane039s counterpart Kaon even protecting her and providing her with energy at a cost to her own wellbeing.
