Midnight Cries

Chapter 1

It had been yet another uneventful day at the Skylark Detective Agency. The most exciting part of the day had been chasing after his client's fluffy, overweight, ginger kitten. Searching for lost kitties can be exhausting but for Hibari Kyoya, it was just a waste of time. Boring jobs were all just part of the territory of being a private investigator. Thrilling cases that got the blood pumping, like tracking down a murderer, were handed to the police, which left Hibari forced to assist herbivores with their ordinary, boring requests.

It was already dark out and Hibari was closing up his sparsely decorated detective agency, when an unfamiliar old man entered the building.

"We're closed," Hibari glared at the intruding stranger.

"I'm sorry for arriving here in this late hour but this is an urgent request," the man replied, his eyes begging Hibari to just listen to his intentions. Hibari observered the elderly man with crisp, white hair and his matching moustache and dressed in an obviously expensive brown, pinstripe suit and carriying a detailed and exquisite scepter.

"Fine, come inside. I'll listen but it better be worth my time," Hibari grumbled. Hibari was only agreeing to listen to the old geezer's request because he figured he would be able to wrangle a ton of cash from this wealthy looking man. Working as a P.I. with few customers, meant that Hibari constantly struggled to make ends meet. This month in particular had been extra tough, as the only person who wanted his assistance was the cat-lady and Hibari's reward wasn't exactly the most satisfiying.

Leading the man to a seat by his desk, Hibari himself seated himself at his plain, wooden desk. "You must be Hibari Kyoya, correct? Thank you for allowing me inside your premises," the man politely spoke, only irritating Hibari more.

"Can we just get straight to business, Herbivore?" Hibari muttered, wanting to hurry up and get this ordeal over with.

"Yes but first, I would like to introduce myself. I am Timoteo and I am the principal of Namimori Middle School," Timoteo introduced himself, while Hibari's glare became more intense. "As I mentioned before, I have an urgent case for you. Two students from my school have gone missing and I would like you to find them."

Hibari was surprised and intrigued by Timoteo's request, after all the only search and rescue cases he received were helping people find their lost pets but still he asked, "Why come to me? This is a job for the cops, not a private detective."

"I have already informed the police but with the recent incidents around town, I fear for the safety of the rest of my students," answered Timoteo, his face fraught with worry.

Hibari knew about the incidents that Timoteo was refering to. In the past week, two mutilated corpses of female students had been discovered. Hibari only knew as much as the news reported but even so, everyone in town believed that the murders were the work of a serial killer.

"What exactly are you wanting my assistance for?" Hibari questioned, knowing there was something more to Timoteo's words than just trying to the find the kid's whereabouts.

"Well, I would like you to work undercover at my school to investigate the whereabouts of the missing girls and also to help prevent any other students from disappearing," he informed Hibari, proving himself capable of handling Hibari's permanant glare. It impressed Hibari that the old man wasn't trembling in fear, like so many others.

"What would my cover be?" Hibari replied, already knowing the dreaded answer.

"I would have you work as a teacher," announced Timoteo. "So, will you accept my request, Hibari?"

Hibari mulled over the job, silently in his head. He absolutely hated crowds of people. So spending time with a bunch of adolescent, annoying, loud-mouthed brats was not his idea of a great time but it wasn't often that he got to work on a case as interesting as this one. Even if it had zero conections with the recent killings, it was still more engrossing and a better use of his time then the pathetic jobs he usually solved. Besides, he would surely be paid handsomely.

"Okay, Herbivore, I'll accept but I have a few conditions. Firstly, you must not tell anyone that I am a detective. The only people at the school who should know my real occupation is me and you. Secondly, you must grant me access to any personal files that I ask for and finally, I expect to be properly compensated for my efforts," Hibari commanded, his harsh eyes locked on Timoteo.

"Of course, I accept those conditions. Thank you very much for accepting my request," Timoteo bowed, gratefully.

Opening his mouth widely, Hibari yawned, "So who am I looking for?"

Timoteo looked downwards and answered, dejectedly, "The two students are Hepburn Iris and Sasagawa Kyoko."

"Papa!" Hibari's daughter, Uni, called out as she ran to greet her father as he entered the door to their home.

"I'm home," Hibari smiled, rustling the top of Uni's little head. Hibari was a cold hearted man, constantly irritated at various things most people find amusing and hated spending time with other people, finding them eyesores. The exception to this was Uni, though. It could be because she was his precious daughter but it was more likely because of Uni's radiant smiles, that made Hibari want to bask in their glow and temporarily become a compassionate human being.

"Did you find Gerry?" Uni asked, her big, blues eyes hoping for a happy outcome, for the kitten Hibari had saved.

"Yeah, that cat is back safe and sound with his owner now," Hibari informed her.

"Yay!" cheered Uni, happily, twirling herself around the room. Watching Uni beaming, warmed Hibari's normally frozen heart. Uni was mature for her age, so witnessing her act like a kid pleased Hibari. Her reason for usually behaving beyond her years was due to the pain of losing her mother, Aria. No, it wasn't death. It was something much, more painful.

Hibari had first met Aria after graduating from highschool. The two had attended the same university and fell in love, shortly after their first encounter. Hibari didn't date much while he was a teenager because the girls were either afraid of him or they irritated the hell out of him. Aria, on the other hand, managed to make Hibari's heart race, due to her lack of timidness directed towards him and the mature, intelligent manner she presented herself as, failed to annoy Hibari.

Their blissful lives, however, were forever changed once Uni had been born. For some reason, Aria became distant, cold and unlike the person Hibari loved. On Uni's first birthday, Aria had disappeared. Hibari never reported her as a missing person, though. That was because when he returned home on that dark, stormy night, there had been a small note left beside the sleeping Uni.

In the familiar, delicate handwriting that belonged to Aria, the note read simply, "I'm sorry. Goodbye, Hibari."

After that, Hibari never looked at another person romantically again. He suffered through a dark moment, blaming himself for Aria departure and drowning his sorrows in alcohol. If it weren't for the fact that he eventually grew determined to take care of Uni, Hibari probably wouldn't have survived being abandoned by the love of his life. Uni was his angel now and he would do anything to protect her bright smiles, that was constantly glued to her face, these days.

Uni never used to smile. Hibari still remembers the day when she asked him if he wished she had never been born because then Hibari would still have Aria in his arms. That question had left Hibari shocked and stunned, that his sweet innocent child could ever imagine something so depressing. He had answered her honestly, telling her that he would never wish for her to vanish from the world, even if it meant regaining Aria, because she is his precious, little angel. This year, Uni's attitude had improved considerably since then, thanks to her fun-loving, joyful classmates, Bluebell, Futa and Fran.

This was another reason for his accepting Timoteo's job offer. Hibari had experienced the harsh reality of losing a loved one. The pain of not knowing if they are being brutally tortured or living their dream life is something Hibari wouldn't wish on even his worse enemies. Female students vanishing hit close to home as well. If anything were to occur to Uni, then Hibari knew he would lose control of himself. So Hibari swore to himself that he would uncover the secrets behind Iris and Kyoko's tragic disappearances. He would return them to their families. If he were to fail in his task then he would just bite himself to death.

A/N: Crack pairing with Hibari and Aria. The only reason for it is because I wanted to make Uni Hibari's daughter for this fic. If you're wondering how can Hibari even have a child, he is twenty-six in this fic. Uni is seven, which makes Hibari nineteen when he had her. Most characters will still have their normal ages, for example, Kyoko is fourteen. Next chapter will have Hibari enter the school and meet people like Tsuna, Gokudera, Yamamoto, etc. Hope you enjoyed reading and please review. Any constructive criticism is welcome.
