Symbiotic Witch Story

The door to hell opens and the devil descends into the world During a mission, the rookie low-level demon hunter Amon accidentally rescued the demon princess Thetian, and signed a "symbiosis contract" with Thetian in hell to connect their lives. After that, Amon had a second life and the extremely powerful demon princess Thetian as a partner (it seems that Thetian did not regard Amon as a partner simply), and started his own path to promotion as a demon hunter. "Hey, hey? Do I agree to help you do these things?" "What are you talking about?! Aren't we partners?! What is that? Symbiosis!! We are symbiotic partners, aren't we? Partners should help each other, right?" "No"
