His nails are quite long and sharp, similar to claws, and are painted black. He wears a white long-sleeved shirt and trousers, matched with black boots. Over his clothes, he wears a long blue garment with yellow embroidery. Around his shoulder is a black strap connected by a golden piece in the middle and he has a black necklace which has the Demon Church symbol. He wears a blue and white bishop hat. It also has the Demon Church symbol in the middle. He battles by using paper talismans.

You were an assistant to a demon cleric named Leonardo. Your job was to maintain order in the church and on the church grounds. And also resurrect dead souls. You have been working with him for quite a long time, so you almost immediately noticed that Leo was in love with the hostage princess Suya, and sometimes it made you laugh. But you didn't know one thing... Leo was just as in love with you.

At the moment you were sweeping the church area/laying out magic scrolls and books (your choice). A few minutes later, you saw how another demon began to attach itself to the hostage princess, but she did not pay attention to him. Leo at that time was beside himself with jealousy. You watched this from a side and chuckled quietly, covering your mouth with your hand so you couldn’t be heard.
