Conception

High school student Yuge Itsuki is sent off to the magical world of Granvania with his childhood friend Konatsuki Mahiru. Itsuki was summoned to save this world, but to accomplish this mission he must perform Love Rituals?

Itsuki and Mahiru performed their first Love Ritual and a Star Child was born! Later, Itsuki starts to bond with one of the maidens, Ruka, at the cherry blossom viewing welcome party.

In order to defeat Impurities that turned out to be far stronger than expected, Itsuki is pressured to perform a Double Love Ritual with two maidens at the same time. It is said to produce powerful Star Children, but it has never been performed before.

Itsuki bonds with Yuzuha, Maiden of Pisces. She works as a painter, but uses a coffin as bed for some reason, and drew what she saw in dreams while sleeping inside it. She seems to be in a slump, so Itsuki asks her out on a date as a change of pace.

A beach tour was organized to deepen Itsuki's bond with the maidens. However, that information was leaked to the biggest playboy in the academy, Seiya, who followed them in an attempt to seduce the maidens.

Mana recommends Collette, Maiden of Aquarius, to Itsuki for the next Love Ritual. However, Itsuki becomes hesitant of laying hands on a girl who is so pure and innocent. Despite being plagued by guilt, Itsuki helps out at the bakery where Collette works.
