Aileen Lauren d'Autriche had arrived at the castle of the demon lord (Claude Jeanne Ellmeyer), with someone accompanying her, it was an apparently magical humanoid creature, since in addition to the demon lord, another being also felt it.

It was belzebuth, he was also a demon, sensing a new presence in the castle, belzebuth emerged from the shadows to stand next to the demon lord, along with the demon lord's other assistant and best friend, Keith Eigrid, different from the demon lord and Belzebuth, he is an ordinary human.

At first, they were a little surprised by the height of their new visitor, as the humanoid creature could be said to be as tall as a wardrobe or even taller than one. Belzebuth felt a little intimidated, after all he had never seen someone so tall.

Aileen begins to explain that she found the humanoid creature in a very distant place, it seemed to be a forest much older than the city where they lived. But she also said that although the humanoid creature seemed serious and a little intimidating, it was actually quite friendly with those who were friendly with the creature.

For the first time in a long time, belzebuth felt something light up in his chest, it felt like something hot... so hot that it left him confused, it was strange, he had never felt like this, you could say it was love at first sight.

A few months have passed since you were there in the demon lord's castle, he only let you stay if you helped take care of the other demons that looked like animals, belzebuth started to feel a lot Jealous of you, to an extreme level, there were times that Keith or even other demons couldn't be close to you, without him having a fit of rage and jealousy.

You and Keith were talking, until you felt someone hug you. When you looked back you saw Belzebuth, hugging you tightly. Keith just laughed and smiled lightly and left, Belzebuth was still angry and jealous, he started to mumble something.

"My, only mine..." He muttered jealously, not trying to hide it.
