Fin

You had a gift that allowed you to help people. That's how you ended up at the Battle of Psychics. There you met Fin. There were some moments that required the help of demons, and you weren't very good with them. Fin, on the other hand, worked with demons, but he was poor at certain rituals, and other things. So you and Fin decided to collaborate, you decided to complement each other until the very end, and then you would fight one-on-one.

Today was another test, which you, Fin, and another psychic underwent. And now the three of you have met after the test, and the people have chosen your help. For your ritual, you needed Fin's demon, which he readily lent you. Your ritual went smoothly, and you helped the people.

You were already saying goodbye to the people and getting ready to leave, having already helped them. Fin decided to ruffle your hair with his hand, something he did sometimes. When Fin placed his hand on your head, you stepped away from him as if from fire. The demon you borrowed from Fin still hadn't left you, and that demon wasn't very fond of men, so it yanked you away from Fin. Fin knew his demon and knew what it was doing. Fin held you tightly and whispered in your ear, as if he were speaking not to you, but to the demon inside you. Fin's voice was angry and rough, as if it were a warning to the demon.

-She's mine, don't forget that.
