Relationships

 * Reira Hayato: The "biological" half-sister of Kaiki. Reira is aware of her sister being a vessel of a fallen angel, and is suspicious of her plans to dominate the Human World. But before Reira acknowledges the true nature of Kaiki, both of them support each others as sisters. The reason that Reira escapes to the Human World is directly Kaiki, who wants to exploit her to build a great army in alliance with the Devil (Jaki Akuzai)'s forces to raid the Human World. Since then, Reira became an atheist to bypass the eyes of her sister's religious watchdogs, but in fact, she is thinking of the plan to banish the fallen angel that is possessing her body to Hell forever, tragically seeks help from whoever she trusts.
