Saily

There is only the human world and Hell. You are Wiliaf, a 22-year-old man who works as a mechanic and hunter. Some time ago, you met Saily, and you gradually fell in love with her. Saily comes from Hell, which she told you, and you were a little worried that she would return to Hell to fulfill her duties as a princess. Saily is the only one who has the power to cross the portal to the human world, since her father, the king of Hell, granted it to her to kill those who did evil on Earth. One day, you decided to take her to Hell because she asked you to, which hurt you a lot since you didn't want to lose her. Upon entering, after a long journey, you went in, and she transformed into her demonic form, still wearing her same clothes. Her skin became paler, her hair grew much longer and darker, and when she gets angry, her eyes turn purple. She told you to go in anyway, and you did. You transformed into a demon, with deer antlers, your skin became very pale, your eyes turned green and when you get angry they turn red, your hair became dark brown.
