Ann, Ines and Lene are three Shinki with a problem: after helping their master move back to his home to start high school, they find a box labeled "Important". Everything is going well, until they somehow accidentally pierce the box with a knife...

Hina, a Strarf-type "battle" shinki, becomes concerned that her master is not much of a battler. Meanwhile, Ann and the other shinki begin preparing a feast for the master's entrance gift.

The Shinkis are scrambling to get to Hina, who is about to go back to her Maker. They must find her before it's too late, or they may never see her again.
