Chapter 1

The Demon and the Girl

The sweat drops were falling on the metallic surface, where her panic face was reflecting. Yako wondered how many hours had she been in there and why. Just after she had decided to be the most helpful to Neuro after the KamiKiri hairdresser fiasco, she had promised Aya to become a better detective. And by the way, she had already gotten her portion of verbal abuse for her mistake the day before.

It simply wasn't fair, she remembered how she had accept to help the demon as façade in gratitude about him solving her father's murder, but since then she had been submitted to horrendous torture devices.

Moreover Neuro wasn't anywhere near to enjoy her suffering. He had left her there, hanging from the ceiling, with both hands and feet tied up on her back. Not only she could describe it as uncomfortable but also, the demon had placed a bear trap exactly under her chin. The moment she decides to low her head, her neck turns into tomato soup.

This abandonment play was the worst torture ever; her back ached as well as her neck. The sun was going down and she started to foresight the moment her boss enters the office to find her plain death.

She heard some bell ringing, it was her cell phone; probably her mother, worried by her long absence. Usually she'd be home for dinner just by that hour, and man she was hungry! Even when that silly tear was hesitating to fall from the corner of her eye, she wouldn't ever give Neuro the joy of seeing her crying.

"My, my, you seem to be in great trouble" a man's voice called from the other side of the room. Unfortunately he was out of Yako's vision.

"Who's there?" she shook back and forth; it unlocked a new unknown function in the torture device, every time she moved, the rope loosed a little, centimeters closer to death. Once noticed this, she restrained herself to move, even though the yet-to-know person in the office was starting to chuckle. Yako sighted, this must be another of Neuro's tricks. Maybe she was talking with a recorder as far as she knew.

"Hum, could you please help me? Remove the trap, please." Yako plead in a pity tone, this was no time to wonder who that person was, but to save her own neck.

"Why? You seem to be having so much fun."

Then she could hear the paced steps of someone walking towards her, which meant there was actually someone with her in the room. She wondered if that someone would indeed remove the trap, or tries to take her down by pulling, her heart was beating like mad. After some seconds of deathly silence nothing was happening, then a shadow stood up in front of her and the surprise made her to move, loosening more the ropes.

The 'someone' was a kind-of-man creature, he was wearing black boots with high heels, black leather midriff jacket with long sleeves, and shorts that left way much to see his pale skin. But what really looked out-of-place was his face, was he wearing a raven mask? He was looking down at her with amusement. Yako stretched her neck as high as she could, and then she realized the guy had red shiny eyes, similar to Neuro's when a mystery was near.

"Y-you... you are a demon!?" she gasped with a half I'm-screwed-smile as her interlocutor responded with a crooked one.

"What a witty girl you are. Perhaps you may know it, since you summoned me."

Yako was in utter disbelief, since when had she done such thing? The self-proclaimed demon kneel in front of her, she could see some black feathers mixed with his hair of the same color, and a twisted tattoo under his right raven eye, he approached offensively close to Yako's face.

"Now it's your decision whether to make a contract with a demon" he talked smoothly, numbing her mind. His lips practically touched hers, Yako snapped back to reality and struggled, the rope loosed for the last time and the only thing she could hear was the metallic sound of the bear trap closing– after all the price had already been paid.

When she opened the eyes she was laying on the floor, her restrains had left just a painful memory on her wrist and ankles. She sat up to realize it was already dark.

"So, what about the contract now?" the demon was still there, waiting on the couch next to her with that puzzling smile of his. He was holding the bear trap on his black nailed hands, opening and closing it as if it was a simple book.

"Thank you for saving me...hum... Demon-san. But I don't have interest in signing a contract with you" Yako stood up aimlessly, her legs not responding quite the same. "At first I thought you were Neuro's friend so..."

"Neuro?" The demon diverted her speech. "You mean Lord Nougami Neuro? ¿Does he live in here?"

She didn't expect that reaction. The demon stood up and started to walk from one side to another in the office, holding his chin with the hand like thinking serious business. The turned towards Yako, who was already checking her phone inbox.

"May I know if he had put you in that situation of danger?"

"Eh? Yeah, he's been lately very... creative with the torture methods." This answer sickened her, as it seemed she was getting used to the former abuse.

The demon wandered again by the office not paying attention to her. Yako stared at Tokyo lights as she thought when would she be able to return home, was it good idea to close the office and leave her boss outside?

"It seems I'm in deep trouble!" the demon burst, placing the back of his hand over his forehead and falling backwards dramatically.

"You know? Neuro may be back in some hours. I can leave the office open for you, a pleasure to meet you." Yako had arranged her backpack, not wanting to know what Neuro had to do with the newcomer, after all it was too late and she knew demons were all the time up to no good.

But before she could even touch the doorknob, the demon blocked her way outside. Yako took two steps backwards before falling on her back.

"You seem to do not understand," he said his reptilian eyes fluttering between the pink and red "Lord Neuro is one of the most feared yet most respectable Demons in our world. It was of my knowledge he had decided to live in the human world, but it was far of my calculations he was sharing his life with a human. If he discovers I messed up the game he had with his toy, I'm done for."

She heard him not moving a muscle, if this demon was also afraid of Neuro, this might make him more appealing. The demon lent her his hand for helping her to stand up, she accepted it in silence.

"So, you rather not stay here for when Neuro arrives?"

"He'll probably find me.

"Don't worry, I'll tell him I escaped the trap myself; I just have to figure out how."

"Anyway I don't have anywhere to go." The demon lean on the door and sighted. "And just imagine how tiresome is to come from the demon world to realize no one was summoning you to start with.

He sent her a complaint look.

Yako rummaged inside her school bag to pull out a half eaten candy bar.

"Here. It's the only thing I have left" as soon as the demon grabbed it she repent, how was she supposed to bear the return home before dinner without it?

"I can't eat this." The demon returned it to her, half smiling.

Yako's eyes gleamed with expectation and before she could even notice there was left only a tiny bit of the chewed candy on her hand.

"Do you feed of mysteries, too?" she attempted while munching the glorious sweetness.

"Well, perhaps my appetite is as gourmandize as Neuro's," the demon looked exactly at Yako. She trembled, as the idea of him eating teenager girls passed her mind. "I eat revenge" he stated.

Author's Note: Thank you for reading this first chapter. It's been a long time I've thought about writing a Majin Tantei Nougami Neuro, not sure about what to do it. But after reading Kuroshitsuji this idea immediately appeared in my mind.

This fic is already finished in my computer, so don't worry you'll see an end to this sooner or later. My main problem is that English is not my mother language, and corrections take me more time that the real writing ^_^
