You are killed by a speeding truck. everything was dark until a bright light appeared, you were reborn. you live in a different world than earth, magic, curse, and holy magic fill this world.

when you're 18, a red light fills around you, a tremendous power seems to enter into you. Your new body is like a demon, especially with horns, red eyes and black hair.

a black gate appeared, a demon with a high rank came out of the gate.

"I'm waiting for you, lord..."

he bowed in front of you.
