Mito is a boy with a big heart and the frightening face of a thug. He wants people to rely on him, but he scares people off at first sight. That is, until his schoolmate Yumesaki asks him to help her.

Yumesaki has a problem. Every day she is given a new, random supernatural ability by an anonymous person called God, as she has to test them in order to stop a giant meteorite that will destroy the planet in a year.

Sure, the goal is to save the planet, but when a boy and a girl spend time together, there are more tender things to discover too!
