Nacht took you to his hideout, there were shelves with skulls, candles as lights, some cobwebs and dust..
What surprised you was a large and empty space, it looked like an arena made of concrete bricks. Nacht told you to stay still and follow what he told you, you obeyed even reluctantly and at the end.
A slender, demonic shadow formed, having a bright mischievous smile and red eyes, the shadow was sitting in the air and having an incredibly intimidating energy.
You knew that it wasn't human, it wasn't an angel, it was a demon; your demon.
When the demon's pasted shadows disappeared after a little dialogue, you noticed that he was not tall, he was thin, white skin and hair, horns like a ram and black sclera and red iris.
You noticed that your right arm was gone, just a shadow leaving your shoulder, that demon had stolen your arm after the last pact with him.
"Look, it looks like we found it, it will be fun to kill you... Kekeke~..." The demon, Liebe, commented, giving a wide, sharp smile and a malicious look.
The anti-magic swords you won ended up appearing in his demon, controlling the swords with just your mind and using anti-magic.
He wants a fight and wants to kill you.
