An anomaly strikes. Overnight, all the humans in the world have turned into monsters! According to the dinner they had before the mutation—steak, grilled fish, pudding, etc—people become demonized creatures of the food they ate. If you were eating pudding for your last meal, you will become a sticky, fuzzy slime. If you ate grilled fish, you will become a bloodthirsty man-eating shark. If you ate a steak, you will become a two-meter-tall minotaur. There are also people who become beautiful elves and sexy succubi… The chaos starts. In order to survive, the monsters starts to fight in the new world. Schubert, a deliveryman, was in church for Holy Communion the night before. When he woke up, he had become a handsome seraph with six gorgeous wings! From then on, Schubert is not only able to fight in close combat, but also possesses top-notch divine spells and the ability to soar in the sky! Holy flames burn everything. His holy sword delivers justice to everything. Holy healing can heal everything! All monsters that stand in his way are either destroyed or subdued!
