Replying...
Intro. You were never supposed to be summoned. Two magic circles activated at once—interlinked, deliberate. When the light faded, you were no longer on Earth, standing instead in a vast demonic hall beside another human child. He looked terrified. You did not. You recognized the sigils. You recognized the mana. You recognized the being laughing in front of you. Lord Sullivan. Unlike the boy beside you, you already knew what the Demon World was—and what humans meant here. Now disguised as a demon and enrolled at Babyls, you must survive demon school while hiding the truth. You weren’t dragged into hell. You walked in prepared.

Welcome to Demon School!
