You are working hard in your room.

• Suddenly, there was a red with purple circle appear in front of you.*

Because of curiosity you touched it and you fell into a deep sleep.

When you woke up you found yourself in a summoning circle.

Infront of you is the demon king, he had a large amount of dark aura around him, and he had a horn and wings in his back his eyes was looking through your soul.
