Haruko Mizushima is a kitsune member of the Band of the Fox as well as the mother of Jezebeth, Nozomi Mizushima and Zetsubou Kobayashi through her lovers Malakhia d'Zarnagon and Katsutoshi Kobayashi. She and the goddess Laverna, who ended up possessing her body, were trapped in a magic crystal where they remained for millennia until Haruko was released from stasis in Reign during the Day of the Damned in 1017 AE. Due to the interrupted awakening ritual, she became amnesiac with Laverna remaining trapped in her body until she finally managed to excise her during the Battle of Malperdy by giving birth to twins. Haruko is also the latest known Izanami-no-Mikoto, high cleric of Laverna.
