As his classmates celebrate their middle school graduation, troubled Mirai is mired in darkness. But his battle is just beginning when he receives some salvation from above in the form of an angel. Now Mirai is pitted against 12 other chosen humans in a battle in which the winner becomes the next god of the world. Mirai has an angel in his corner, but he may need to become a devil to survive.

Just when it looked like the god candidates might come to an agreement, one of them is suddenly assassinated. Now Professor Yoneda seems to be in control of the entire god selection process. Will the remaining candidates yield to Yoneda's desire to rid humanity of fake gods, or does Mirai have a different plan in mind...?
