A/N: Hey team! I am completely and totally loving Blue Exorcist (yay Netflix!) so I decided to write out this little idea that's been fluttering around in my head for about a week. I'll continue it if I get interest from anyone, so hopefully other people like it too! I'm honestly excited about the idea :) Enjoy!

Prologue:

"Samael, I'm in big trouble."

Mephisto Pheles looked up from what he was doing at his desk towards the window. The female demon climbing through it looked young; her silvery blonde hair was a mess. Her glowing skin was covered in scrapes and bruises, golden eyes wide with fear.

The purple haired Demon King sighed and put down the paper he was reading, "Tlanextli, I told you that my name is Mephisto Pheles here. I don't want to have to repeat myself again."

Her eyes narrowed slightly, "And I told you that my name is Li, nothing more." Upon seeing his disapproving gaze, she lowered her eyes, "Apologies, Mephisto."

He grinned and stood, towering over the demon before him. "What do I owe the pleasure of your visit today, Tlanextli?"

A muscle in Li's face twitched when he used her full name but she shook her head and continued, "I might be in big trouble. Actually, scratch that, I'm in huge trouble."

"Yes I got that when you appeared in my window saying the same thing." Mephisto blinked and looked around, "Where is Amaimon? Was he not with you?"

"Yeah, about that…I lost him on the way here…" Li trailed off, searching for the best way to approach what she wanted to say.

Mephisto raised an eyebrow. The light demon before him was usually not so hesitant in her words and actions. He frowned.

"Tlanextli, what is going on?"

"I'm pregnant."

The Demon King clapped enthusiastically and grinned at her, "This is wonderful news! Who shall I congratulate?"

"I think that should be quite obvious," Li huffed, "dear uncle."

Mephisto stared at her, "I am not your uncl…OH...oh dear." He buried his face in a hand, "Tlanextli, how did this happen?"

"Well when two demons love each other very much…"

"You know what I mean," he frowned, "Wait did you say love?"

"It's a human phrase to mock someone asking how babies are made. You think you would know that when you're around them all the time," Li rolled her eyes.

"So you don't love Amaimon?"

"I didn't say that."

"You and Amaimon are in love?" Mephisto looked completely flabbergasted.

"I didn't say that either."

The two stared at each other. Mephisto sighed and gestured for her to take a seat.

"I think maybe you should start from the beginning."

Three Months Ago

"Why me?" Li groaned. She grunted with effort as she carried the unconscious boy on her back. Of all people to find horridly injured, why did it have to be him. She pushed the door to her home open and locked it behind her. She deposited the boy on her bed and sat down heavily on the floor.

The Demon King of Earth was unconscious on her bed...it took a moment for it to sink in...oh God the Demon King of Earth was on her bed.

After taking a few seconds to catch her breath and scold herself for getting involved, Li rose from her spot on the floor and went to her bathroom to get the first aid kit. She peeled off the Demon King's shirt gingerly with sincere hope that he would not wake until she was done. As she cleaned his wounds and bandaged them, Li tried to recall the thought process of even helping him in the first place. As a light demon, she was under Lucifer's domain, but lived here in Assiah. The only two who knew she was here was Lucifer and Samael…or Mephisto or whatever he went by now. If either of them had found out that she left Amaimon alone while injured she would be in deep water.

"Who are you?"

Li shrieked, throwing herself away from the Demon King of Earth. His eyes apathetically followed her from her place above him to the wall. How long had he been conscious?

"Amaimon," she breathed, sinking to the floor and lowering her head to touch the ground. Out of all of the demon kings, Amaimon was the most unpredictable. He could kill her with no effort or he could leave her alone and everything in between.

She muffled another shriek when she looked up and Amaimon was two inches from her face. Li held perfectly still as the Demon King of Earth examined her.

"Why are you glowing?"

Li blinked, her gaze flickering to her hands and back. Amaimon's eyes widened when the light emanating from her faded until it disappeared completely, ignoring her muttered apology. Normally Li kept her light inside since she lived in Assiah, but Amaimon had startled her and shook her control. "Do that again!" he demanded. Eyes never leaving the danger in front of her, Li watched as Amaimon's eyes widened in delight when her skin started to glow once more. She didn't think it was possible, but he leaned in even closer to her.

"You smell good, like candy," Amaimon frowned, "Why are you on the floor?"

Li stood slowly and straightened up when she was sure Amaimon was not going to kill or maim her at this time. "My name is Li. I am a light demon."

"That doesn't sound like a demon name. Why do you smell like candy?"

She huffed, "My full name is Tlanextli. I use peppermint shampoo and soap."

Amaimon looked impressively apathetic and distraught at the same time, "So you don't have any candy?"

"I think I have some lollipops in the kitch…"

"Hurray!" the demon king cut her off, jumping on top of Li and knocking the wind out of her.

"Ouch," she whimpered.

"Tlanextli, lollipops!"

Li stared in bewilderment as Amaimon hopped off her and left her room, presumably in search of lollipops.

Just what had she gotten herself into?

A/N: I've never realized how hard it is to keep Amaimon in character! My hat is off to those who do it so well in other Blue Exorcist fictions. Please let me know what you think! I am sustained by reviews and feedback :D As this is the prologue, it is short. The next chapter should be longer. See you next time!
