While researching parallel dimensions , Yumemi Okazaki and Chiyuri Kitashirakawa find themselves in a world with a particularly high concentration of magic, but after taking hold of a parallel Shinmyoumaru, they accidentally awake the wrath of the island'd goddess, a parallel Eternity Larva. Now it's up to Yumemi to fight in a turn based danmaku combat and dodge Larva's scales.
