A/N: Welcome to the first official chapter of Blue Exorcist! Do we even really count prologues anyway? Please enjoy and review! Reviews make me a happy writing Serpent!

"I had no idea that Amaimon had taken such an immediate liking to you," Mephisto mused, interrupting her.

Li paused midsentence and stared at him. "What on earth are you talking about? You do know that he's the one I'm running from right?"

"You saw Amaimon when he was weak and he hates to have anyone see him at less than full strength. He didn't immediately kill you but rather spoke with you and was playful instead of murderous. Very interesting."

"That's not taking a liking to someone, that's being normal," Li grumbled, "Are you going to let me finish?"

"No no, not right now," Mephisto said airily, waving his hand at her. Li glared at him as they sat in silence for a few minutes. Finally, he nodded, "I've decided what to do. You will attend True Cross Academy and be under the protection of instructors and students until your child is born. The birth of his child should calm Amaimon down."

"How does that-?"

Mephisto cut her off, "Demons are very protective of their children, even when they are not born yet. Amaimon is not pleased though, is he?" He nodded to himself when Li reluctantly agreed with him. Mephisto stood and examined the junction where Li's neck met her shoulder, grinning when he saw the bite mark from two sharp canines, "On one hand, I would say he is acting this way because he is not mated with you yet, but I see that is not the case. He is reacting poorly because he doesn't know how to handle what he is feeling, so Amaimon's logical answer is to get rid of what's causing him such confusion."

"Did you say logical answer?" Li sputtered.

"It is Amaimon's logical answer, not mine," Mephisto frowned, scolding her, "Now stop interrupting me." A muscle in Li's face twitched, but she kept quiet. "As I was saying, demons are protective of their children. In fact, closely related demons, for the most part, will be protective as well."

Li raised an eyebrow at that. When she opened her mouth to ask a question, Mephisto once again interrupted her.

"Yes my dear, even me. That's going to be my niece or nephew. I am very good at control so of course you didn't notice, even if you did come through my window covered in scrapes and bruises."

"Mephisto, why do I need to go to True Cross Academy when I could just stay with you for protection until the baby is born? You said it yourself, relatives are very protective and you're Amaimon's brother," Li sighed.

"I'm a very busy demon, Tlanextli! Which is why I have the perfect choice of where you'll be sleeping and whose class you'll be in."

Mephisto grinned at her, causing Li to back up slightly, "Why do I have a feeling that you're scheming?"

"Oh dear, I'm always scheming," he said cheerfully. He nodded to the mating mark, "But before you go, best cover that up."

Li grimaced, fiddling with the bandage over her neck. "Keep it covered or else…why can't you ever give a straight answer?" She readjusted the bag on her shoulder and examined the building in front of her. "What kind of director places a girl into a boys' dorm?" she scoffed but continued forward to knock on the door.

"Hey Yukio were you expecti-" the boy who opened the door trailed off when he saw who was at the door.

"You've got to be kidding me," Li growled under her breath, "He saddled me with sons of Satan? No wonder he seemed so confident."

Rin Okumura's jaw dropped, "How do you know about that?! Who are you?"

"Rin, why are you yelling?" his brother appeared next to him with a sigh, examining the woman at their door in the process. She was short and lithe. Her silvery blonde hair was strange and exotic looking, pulled back loosely into a high ponytail that almost seemed to glow. Her golden eyes were observing them dejectedly from under wisps of bangs. Though her ears had the slight point of a demon and her overall appearance practically screamed that she wasn't human, she didn't seem dangerous. Yukio kept his guard up.

Li watched as the two brothers argued with each other, finally pushing through the pair and setting her bag down in the entry hallway. Rubbing her sore lower back, she ignored the confused look that the two were giving her as they closed the door behind them.

"I'm sorry, I-" Yukio voice caught in his throat when Li stretched, the bottom of her shirt rising just enough to reveal her nearly flat stomach. Finally done getting the kinks out of her back, she extended a hand to the two brothers.

"My name is Li, nice to meet you both. I'll be staying and going to class with you per orders of Mephisto."

"I don't mean be rude but-" Once again Yukio was cut off, this time by Rin approaching her and dropping to a squat, pressing an ear and hand to her belly. "Rin!" Yukio cried out, shielding his eyes when his brother's blue flames exploded from him.

When his eyes recovered, Yukio was stunned to see Rin still squatting next to the newcomer, his clawed hands gripping her stomach gently as he stared intently at it. Li seemed unaffected. She was resting a hand on top of his head, ignoring the blue flames swirling around them.

"It's alright Rin, calm down," she said soothingly, "No danger here."

Yukio watched in amazement as the flames receded back into his brother. Rin blinked in confusion and stood upright.

"What's going on?" Yukio demanded, regaining his voice.

Li looked at one of her clawed nails in a nonchalant manner, "What do you mean?"

"You know who we are…you didn't seem surprised when Rin, well you know. You actually seemed to expect it," Yukio answered.

"Demons are very protective of demon children. If they are unborn, that protectiveness is given to the mother as well," she answered with a shrug.

"You're a demon?" Rin asked curiously.

"Is it not obvious?" Li responded.

Yukio looked at her suspiciously, "Who's the father of your child?"

Li gave him an offended looked to which he put his hands up in a gesture of defeat. Yukio still didn't lose the suspicious look, seemingly mulling something over in his mind. To fill in his younger brother's silence, Rin invited Li to pick out a room and then join them in the kitchen for dinner. She beamed and thanked him, leaving to go upstairs.

Rin turned to his brother, "Yukio, what's up?"

Yukio looked up and shook his head, "It's nothing. Just thinking about something. I'll have to do some research on it later."

Rin shrugged, "Alright. I'm going to make dinner." He gave his brother a look and poked him in the chest, "And you better be on time."

Dinner was actually going nicely. Li genuinely enjoyed the meal with the two brothers. She eyed the two of them while she took a generous drink of juice. These two were the youngest siblings of Amaimon and Mephisto. It explained a lot.

"So Li what kind of demon are you?" Rin asked through a bite of food, "Ow! Yukio!" Yukio frowned after he whacked Rin on the back of the head, "Don't you have any manners? Don't talk with your mouth full."

She chuckled, "I'm a light demon."

"That's a pretty high class demon to be living in Assiah," Yukio said conversationally.

Li resisted the urge to roll her eyes, "I like Assiah."

"What do you think of the food?" Rin jumped back into the conversation. Li gave him a fanged smile, "It is excellent." Rin shouted an exclamation of success, punching his fist into the air with victory.

Yukio sighed and rose from his chair, "I think it's time to go to bed. We have class early in the morning. Since you're coming with us, you should probably get some rest."

"Early morning class?" Li groaned, "I hate getting up early."

"That's too bad. If the director put you with us for class too, you've got to get up," Yukio gave her an innocent smile.

"I hate you," Li grumbled under her breath, standing and following the brothers out of the kitchen. "Goodnight, Li," Rin said cheerfully when she stopped at her door, Yukio echoing his brother less enthusiastically.

"Goodnight."

Li shut the door and leaned against it, trying her best not to slide to the floor in an exhausted heap. She quickly changed into her pajamas and crawled under her covers, hoping for a dreamless night.

One Month Ago

Li knew from the moment she woke up that she could absolutely definitely not see Amaimon today. She locked the door and downstairs windows quickly. She was in the process of locking the windows upstairs when she heard Amaimon's voice, earning a string of curses from the light demon.

"Tlanextli, I want chocolate today!"

She walked into her bedroom to see the demon king sitting crossed legged on her bed. Li grimaced and avoided eye contact with him, "Amaimon, I can't see you today. You need to leave."

The Demon King of Earth pouted at her, "But I want candy."

"Go see your brother then. You can't be here."

Amaimon's expression changed from pouting back to his usual apathetic but somehow stubborn gaze, "Why not?"

Li groaned and buried her head in a hand, "Amaimon, I don't want to have this conversation with you." When he continue to stare at her, she sighed, "You can't be here unless you like me. I'm in heat."

"I like you."

"That's not what I meant…" she trailed off when Amaimon invaded her personal space, putting himself really close to her. "What if I knew exactly what you meant?" Li blinked rapidly, trying to clear her head. "Amaimon, I don't think you have a full understanding of what's going on. Maybe you should go talk to your brother first." The demon king continued to stare at her.

"Amaimo-"

Amaimon stifled her gasp when his lips pressed against hers forcefully. "You smell good…better than candy," he growled when he finally released her lips. Li stared at him with wide eyes. He was completely entranced by the scent of her in heat. He descended once again upon her, his sharp canines nipping her lower lip.

For once, the danger of Amaimon didn't cross Li's mind.
