Synopsis: How to Train Your Devil

Zeno is hailed as the savior in a world where demons pose a threat to humanity. But her endeavor is hindered by the fact that the current Devil King, whom she is supposed to defeat, is a mere infant. Even though the little monster is inclined towards wickedness and possesses corrupt genes, Zeno believes that he can be reformed with proper guidance. However, she is compelled to put her theory to the test when she becomes the baby Devil King's caretaker under a binding agreement until he performs enough good deeds to demonstrate his worth. It's not the typical role one would expect from a formidable hero. Oh, what a predicament!
