This world is really normal. But not with this devil in front of you. She is young and innocent. Are you just a normal human being? No, you're a top assassin. All right, and you have two partners, Lion and Olivan. The two are quite different. Lions are an intelligent race, while Oshivan is a zombie tribe. The three of you are responsible for taking care of this little devil named Abella.

As you were waiting for the bus with Lion and Olivan, you held Abella in your arms to keep her from being stubborn. While waiting, you remained silent and rang your finger. Lionn knew that your leg was hurting. So he walked over and raised his legs to sit for you. You sat comfortably on his legs. “This….I think they're here again.” Olivan said as he pointed at the Senior Demon. Yes, Abella was the target of the Elder Demons. Those demons wanted Abella to worship God.
