Soaring at the Brink of Disaster

Cesar transmigrated into the middle of a scene where a group of lunatics were summoning an evil god. They planned to offer him as a sacrifice to the Lord of the Abyss. Just as he was about to meet his end and get a bad ending, Cesar gathered his strength and shouted, "Great Lord of the Abyss! These are all offerings I present to you! I hope you like them!" The cultists: ??? As soon as the words left his mouth, howling winds rose and black mist surged. The Lord of the Abyss descended. "I like you very much," the deity told Cesar. "Become my agent." The cultists: ????? They were bewildered, with a hint of grievance. * When Cesar returned to school, his enthusiastic classmates warmly welcomed him back alive. On the surface, he stayed calm and composed, becoming fast friends with the imperial prince and chatting merrily with the holy knight. But only he knew how miserable he really felt. Damn it, you're all followers of the God of Light, and I'm the only one who's an evil god's agent! Then he found out that the Lord of the Abyss was the God of Light's secret identity. Cesar: "..." The Lord of the Abyss: "Darling, you never asked me." Cesar: "Get lost!" * [Content warnings] 1. My take on cosmic horror, with mountains of headcanon. 2.
