"YOU WANT ME TO FUCK RIN?!?!?" Sin exclaimed. Mephisto nodded. "Yep. I want you to get pregnant with him too." Sin just stared at him. The thing that worried her the most was probably the fact that she did not feel like having a kid. "I-I.. WHAT!", she exclaimed. "It's an order by the Vatican. Don't do it and they wont have a good reason to keep Rin alive, since he doesn't have good control over his flames.", Mephisto explained. "You have until January, also two months. If you are not pregnant by then Rin will be sent to execution.", Mephisto said. He then dismissed her. 

Sin walked towards her dorm. Her tail was lashing with rage and she was glaring at the ground. When she reached the dorm she smelled food and went to the cafeteria, where Rin and Ukobach had cooked something. Sin sat down and thanked them for the food, eating it in silence. The only sound to be heard was the chewing and her tail as it whipped back and fourth. Damn Vatican. Think they can use us as they please...

"You seem really mad, something happened?", Rin said breaking the silence. Sin looked up at him, giving him a glare that sent chills down her spine. "Mephisto made a deal with the Vatican involving us. It isn't really one I like, but he will kill you if we don't do it.", she grumbled. Rin looked at her, curiously. "What deal?" Sin sighed. "They want us two to mate to see if our kid gets the flames, then if it does train it to be a weapon." Yukio had walked in and heard what sin had said. He walked up to the two and sat down, grabbing some food. "Man those don't get you guys have feelings, huh?", he sighed. Sin looked up at him. 

"Like, I am OK with fucking somebody, since I already lost my virginity, but I don't wanna get pregnant! I'm sixteen for fucks sake!", She exclaimed. Rin blushed a bit at her first sentence, eating the food and listening in silence. "I wish I could speak to the Vatican and try to convince them that my body needs more time to evolve first.", she sighed. Yukio perked up, smiling. "I can take you to the Vatican, but I wont be there to back up your words. If you do something stupid it's on you.", he said. Sin smiled and thanked him. They decided to go there tomorrow, after school and work. 

The same evening Rin walked into her room with blanket and pillow, saying he had a nightmare. Sin of course let him use the spare bed. She laid down in her own bed, trying to get at least one or two hours of sleep. She actually fell asleep at some point, because when she opened her eyes again it was three in the morning. Sin had no clue what to do, so she dressed up and combed her hair. She realized her tail should be OK now, so she brought it forward. It looked almost recovered. One more hour and it would be back to normal. Sin decided to go for a walk around the school. She quickly packed a sandwich in her bag, together with a water bottle. 

When Sin reached outside the first thing she noticed was the Halloween decorations on the main school. The party they were having would be outside it, which weren't decorated. Sin guessed that the teachers had made the decorations. She saw was about to go out when she realized there was a letter outside the door to her and the two twins' dorms. She opened it, revealing a letter which seemed to be written by Mephisto.

'Hi hi, Sin. I know you will be reading this, since you are always awake first. That insomnia ain't leaving, huh? I have placed lanterns here and there, inside the school. There are a total of fifty three. I want you to light them with your flames. The lanterns can be anywhere between first and highest floor. They can be in classrooms or hallways, none in the bathrooms or anything like that. Good luck! /Mephisto <3'

Sin sighed. She walked into the school building and decided to start on the highest floor. After about two hours she had lit forty eight of the lanterns. She was currently at the first floor. Half of the floor had been cleared. She peeked into a classroom and let out a sound of satisfaction as she found another light. Forty nine done, four to go! Sin walked through the hallway, checking the doors. There was another lantern in the hall, which she lit. As Sin lit two more, she realized she had checked everywhere. There was one lantern missing. Sin walked outside of the building and found it. There was a big lantern hanging at the entrance of the school. Sin quickly lit it. When she was done, she walked out of the building.
