It was raining at True Cross Academy, and a certain group of Cram School students were goofing off in the classroom while they waited for a certain teacher – who was late. They had managed to sneak a baseball into the classroom, and now they were taking turns tossing it back and forth to each other.

Rin, the current holder of the ball, noticed that Shima was spending more time watching the way Shiemi's skirt flounced as she moved between the desks than watching out for a ball, so he chucked it at his head, and it found its target with a thud, knocking him to the ground.

"Ahh, Rin, what the heck was that for?!" complained Shima.

Bon retorted, "Che, It's your own damn fault for paying more attention to the girls than to the game!"

"Uwahh, no fair! I'm a guy, I can't help it! You know you're just jealous because I'm unashamed about it – OW!" Izumo hit him over the head; "We're dating now, so you shouldn't think like that anymore! Seriously!" "Sorry Izumo-chan."

Konekomaru then glanced at his watch. "Hmm… guys, Okumura-sensei is twenty minutes late. Do you think he's okay?"

Rin snorted "Pfft, he'll be fine, you'll see-"

The door opened, and in walked Yukio, their very late teacher, and he wasn't alone. There was a girl behind him; she had bright blue eyes, deep blue hair, a teal halter blouse, deep blue skinny jeans, a book bag, a Japanese sword in an elaborate royal purple sheath at her waist, and strappy black heels.

Yukio said, "Everyone, this is Rayla Suzuki, a transfer student from the American Branch."

"Hello. I'm 17 years old. It's nice to meet you." She said. She then took a seat at the back without another word. Yukio said, "Alright, let's begin the lesson."

Half an hour later, the bell rang for lunch. Yukio gave them homework, packed up his briefcase, and left. Everyone else slowly got to their feet, stretched, and made their way to their lockers. Rayla followed to see where they ate their lunch, and when they took a seat under a tree, she promptly sat on the fountain. She ate quickly, and once she finished, she pulled out a sketchpad and a pack of colored pencils and began drawing. The bell rang, and she packed up her stuff and went back to the classroom. When the others got there, they found her sitting at the back again. Shiemi decided to try to get to know her, so she took a seat next to Rayla. "Hello, I'm Shiemi Moriyama. So what brought you to Japan?" and Rayla said, "To be with my brothers."

Shiemi smiled and said, "That sounds sweet! Do they attend cram school?" and Rayla's cheeks lightly flushed, and she went silent. This confused Shiemi. "Do you not want to talk about it?" and Rayla simply shook her head. Shiemi nodded and said, "Okay, that's fine. Well, I'll tell you about me then. My mother owns the Exorcist Supply Shop here, so I've known about demons my whole life. I met Yuki-chan a few years ago." Rayla said, "Yuki-chan?" and Shiemi said, "Oh, right, well, Yuki-chan is my nickname for Yukio, the teacher who brought you here." And Rayla nodded in understanding.

The rest of their day went smoothly. They had a fitness evaluation Tsubaki's class that everyone met all requirements. He told them that they would start going on regular missions starting in a week, and that they would need to spend time getting to know each other, and nobody missed how his eyes lingered on Rayla, who hadn't said a word the entire time.

Then they had their summoning class, and they learned about "mount familiars," which are large and strong enough to carry their masters.

At the end of the day, everyone lingered to talk to each other; everyone except Rayla, who ran into the hall as soon as the bell rang. Shiemi went to investigate, but Rayla was nowhere to be seen. Shiemi went back to the classroom, where she said goodbye to her friends before going home.

[ In Mephisto's Office ]

The headmaster was sitting at his desk, eating ramen and watching an episode of his favorite show when the door opened, and in walked Rayla. He took one look at her face and knew something was wrong. "Rayla, what's wrong? Surely it went okay?"

She shook her head and said "I couldn't tell them. Not yet. Nii-san, what if they hate me?" and she started crying. Mephisto set down his food, walked over to her, pulled her into a hug, and said "There's no way they could hate you. They would have to be the most ignorant bunch of baboons in existence if they did. In case you've forgotten, they accepted our little brothers alright, so why would they single you out?"

Through the tears streaming down her face, she said, "They got to know Rin and Yukio as people long before they learned about father, and even so, they were still hateful at first. So I won't tell them, not yet anyway." Mephisto nodded and said, "Yes, that is true. So, do you have any kind of timeframe of when to tell them?" She shook her head and said "No, but I'll have to be careful. We're going on missions in a week, and so Tsubaki-sensei wants up to get to know each other. What should I do?"

He simply said, "Do what feels like the right thing. Little sister, there is a reason why we called you the little general back home. From the start, we knew that your strategic skills even rivaled mine. For now, get some rest; you'll need it to keep that little mind of yours working. In the meantime, I'll pile together all your skills and weaknesses and find which ones would not blow your cover immediately." She nodded, wiped her eyes, and went to the nearest door, pulling out a key as she went. Once she was through, Mephisto went back to his desk, opened his computer, and set to work.

[ Rin and Yukio's Dorm ]

Rin lay in bed, thinking about the events of the day.

Rayla hadn't said a word all day after she talked to Shiemi. Rin knew something was up, but he couldn't put his finger on it. He decided he would attempt to talk to her and try to find what was bothering her.

Yukio was at his desk, working on the lesson plans. He stretched and yawned, then checked his work. Finding it satisfactory, he put it securely in his briefcase. He turned to Rin and said, "Hey, nii-san, what did you think of Rayla? She seemed nice enough, but she was completely silent."

Rin looked up and said, "I was just thinking the same thing. Shiemi asked her why she came to Japan, and she said she came to be with her brothers, but then she looked startled and stopped talking."

Yukio nodded and said, "I don't know why that happened, but I'm sure she'll tell us when she's ready. Now go to sleep. You guys have tomorrow off, so you can spend it doing your homework, nii-san." He smirked when Rin twitched. He then turned out his desk lamp and climbed into his bunk.

Rin was awake for a long time, even after Yukio's soft snores filled the room. He eventually fell asleep shortly after midnight, and his subconscious drifted to deciphering Rayla's behavior.

Author's notes:

Ever since finishing the Blue Exorcist anime and catching up with the manga, I have toyed with the idea of Satan having a daughter that almost nobody knew about until she came to True Cross Academy. I have toyed with this idea in my head many times while going to sleep, so for the most part, I should hopefully update at least once or twice a week. (I am SO busy at the moment!) This is my very first fanfic, so I accept all constructive criticism, suggestions, and tips. What I will not accept, however, is blatant hate mail. I get enough bashing for my "Satan's Daughter" idea from my older brother, thank you very much.

GhostMenace2: You are an amazing writer, and I fully admit that I copied the [ Location ] idea from you fanfic, "Demonic Instincts".
