Chapter 1

If there was one thing Tsuna could honestly admit to himself, it was that he hated Namimori. He hated the city with a passion, one that burned on his inside, and made him want to scream out in frustration. It was the most oblivious and disrespectful town he had ever been to and he was trapped here until his mother decided otherwise (However he doubted that would ever happen since she was still hoping that his deadbeat father would one day return and if they moved, he wouldn't know where they were). The people of Namimori disliked him and his mother for being a single-parent family, ignoring the bullying that occurred in the background, and even willingly whispering despicable words to others whenever either of them walked by. The only good things about this horrid place was that crime was almost non-existent or at least very well covered. With the Disciplinary Committee running the entire show, taking over the police, people tended to remain in hiding.

Still, that didn't help Tsuna's situation.

He was bullied often (as expected), both in and out of school. The only safe haven he had was his bedroom as the rest of his house couldn't be considered that anymore. Whispers continuously came through the door as people walked pass their home and eventually, his mother became a victim of them. She believed the gossip surrounding his so-called stupidity and in turn, accused him of never trying, while ignoring all those that were directed towards her. It wasn't fair. Yes, he wasn't the smartest child out there, but he honestly tried his best to succeed. The only issue was that he had fallen behind further and further with each new material and with no one there to help, it eventually became pointless. It wasn't completely his fault. How could he understand the new material that connected to the previous one when he didn't even get that?

Things began to rapidly change when he came across an old book while hiding up at Namimori shrine from his bullies. He had been chased from school and had sought refuge in the old beaten up building, waiting patiently for them to leave by peeking out from the corners. Just as they did, his infamous clumsiness decided to bite back by getting his foot caught on a loose board, crashing downward onto the old floor. The force, his weight, and the age of the wood made it give way and he went spiraling through the boards, letting out a high-pitched scream as he tumbled. Dust covered his vision momentarily and he coughed, sitting up to wave his arms around in an attempt to help clear his vision. Luckily, he hadn't been hurt by the fall, just a small scrape on his right elbow from where he had landed. As the dust began to settle, he noticed that he hadn't exactly gone through the floor boards to the earthy ground below like he had expected, but to another layer hidden underneath.

Tsuna blinked in question, curious as to why there was something like this in the first place. He hadn't heard much about the Namimori shine from the locals or books, just the basics and whatever they sprouted during the festivals. Regardless, he seemed to be the only one that found the holes in the stories a little odd, though not worth noting. Glancing around the small layer, just enough to squeeze an adult through by crawling, he spotted something out of the corner of his eyes. For a moment, he thought he heard a ghostly whisper, but hastily shook his head, believing it to the creaking of the wood and rustling of the wind through the broken pieces. In the very corner, there was, what he believed to be, a small book tucked away as if it had been purposefully hidden away. Tsuna suspected so if it was in this hidden second layer.

Curiosity getting the better of him, he got onto his hands and knees and crawled under the still intact upper layer (considering he made a hole only in the center). As he got closer, he could make out the item better in the darkness and indeed it was a book, a small brown book. He reached out to grasp the item once he was close enough and tugged it towards him, scooting back to the center to examine the book better. Humming gently to himself, he shuffled out of the hole he had created, momentarily peeking out of the shrine area to see if anyone had heard his scream (his bullies specifically) and was relieved to see the outskirts completely void of life.

Using this small moment of freedom, he glanced back down at the book he had picked up and examined the cover. It was small, about the size of his hand, but there were no words or pictures on the protective layer to help identify its origin or what exactly it was about. Blinking curiously, tempted to open the book, he peered down momentarily at his backpack to see what time it was before turning back to the open area in front of the shrine. It was late, no one around, but he wasn't going to be taking any chances. He didn't want to be ambushed or attacked again on the way home while in the dark.

Stepping out from inside the shrine, he took a momentary glance at the book before tucking it into his backpack. His eyes peered over the setting sky and sighed heavily. He needed to get home before his mother noticed his disappearance and worried about him. At the same time, being late kept his mother from asking too many questions he didn't want to hear at all. Sighing, he tugged his backpack further up his shoulders and grasped the handles before taking off.

He could take a look at the book once he was in the safety of his room.

Tsuna stared at the insides of the book, staring in wonder. The pages inside were faded yellow, clearly showing its age, and yet the words and pictures within were fully intact. It was like the ink had been missed by the age, never fading or disappearing. None of the pages were torn or missing, completely intact. It was odd, but Tsuna pushed it out of his mind. The only thing that caught him by surprise was the old style of Japanese it used. He could luckily make out most of it by similarities and what he couldn't, he could figure out by connecting the phrases and dots between the sentences.

He had arrived home in time for dinner (just how he liked it), still earning a scolding for coming back late before settling at the table. It was nothing new. He was used to it by now, and simply ignored it by habit. During dinner, Nana had asked the same questions every meal and Tsuna simply ignored them.

"How was school?"

"Anything new you want to say?"

"Do you have any friends yet?"

"Did you actually pass something for once?"

Tsuna remained quiet throughout the entire interrogation, stuffing his mouth as an excuse to keep quiet. The moment he was done, he excused himself with the need to complete his homework and headed upstairs to his bedroom to hide. He locked the door behind out of habit. Talking to his mother while trapped in his room with her never ended well and he had learned that the hard way. At least if she tried to talk to him through the door, he could avoid it by putting music on and cover the demanding questions. The earlier he did it, the better.

Which left him with plenty of time to examine his newfound book instead of actually doing his homework for the night (it wasn't going to matter anyway).

Spilling out the contents of his backpack on the floor, he spotted the item he was looking for and picked it up. His honey-colored eyes went over the front and back cover carefully once more, scratching at the leather binding to see if maybe the title and author had faded away, but no, there just wasn't anything there. Opening the first page, he read out the text.

"To those that find this book, beware. This is not for the weak, but for those that desire heavily. To make a wish, you must make a trade in return."

He flipped the page to the next one and continued.

"Darkness dwells in everyone, no matter how young or how old. It swirls within, corrupting all that is considered good. It is contagious and it slowly eats away at the very soul until there is nothing left behind but a shell of what was. Beware of the creatures of the night."

Tsuna shivered, suddenly feeling the temperature in the room rapidly dropping. He peered around cautiously, wrapping his arms around his body to keep warm, before finally relenting and getting the blankets on his bed to cover him. The temperature didn't change, the coldness unsettling. The room was empty except for him after all. Shrugging his shoulders, he flipped to the next page to see an image of a circle. It looked like something used for summoning, something that was seen on a TV show that called out demons or gods. This one was more detailed, etched in by a thin pen to show the refinedness of the circle. It wasn't something he recognized from any show. Perhaps this book belonged to a cult or something in the past? That sounded about right.

'Should I really be looking at this?' Shaking his head in denial, he continued. He wanted to know more about this little book. He couldn't help but want to know. He flipped the page, seeing more.

"Pray to the God of Demise, Destruction, and Death. Let him hear your cries of despair. If your desires are true and strong, he shall listen and appear before you."

Swallowing, he shifted in his seat. This didn't sound good, not at all, and yet he couldn't pull himself away from the book. The three big D's were already threatening and he could tell that whatever this cult had been worshipping, it wasn't good. He flipped to the next page to see scribbles that didn't make any sense to him at all, in a language completely different. Connected to it were drawings of what appeared to be the ritual to worship this so-called god. The sacrifice was vague, but it seemed to range widely from animals to the user's own body. He flipped through those pages quickly.

It wasn't until he came up to a certain page that made him pause. It was a drawing of a doorway with what looked like a man standing in the middle of the entrance way. The being was blocked out completely in black, like it had been scratched out, and left Tsuna unable to identify anything about the figure. However, the upper features of the face made Tsuna tremble in fear. He didn't understand why but he did. All that was obvious of the face was the large white eyes that looked like they came out of a scratchy horror show and a wide grin that was unnatural by how it stretched across the face.

Immediately, he slammed the book closed and tossed it underneath his bed. He didn't want to see that image again. It just...unsettled his very being. It was like the creature on the page was watching him from those very eyes.

Not wanting to focus on the subject or the image, he ripped out his homework from the scattered remains of what he spilled out from his backpack and immediately set to work. He needed to distract himself and now. He ignored the coldness of the room by pulling the blanket closer, as if shielding him from the darkness.

The next day, Tsuna could feel something watching him from behind. He didn't know exactly what, but there was something there, following him in the background no matter where he went. It didn't matter if it was at school, the bathroom, to the store, or even in his own bedroom, it was there. Tsuna would peer around hesitatingly, wondering where it was coming from exactly, but there was never anything there. He felt constant shivers along with the goosebumps that sprouted on his skin whenever the gaze shifted closer, making him almost want to scream. It was like he was franticly becoming paranoid, glancing behind him in class or over the shoulder as he walked down the streets and even opening doors to see if there was someone on the other side watching. No one noticed the drastic change, not as if anyone really paid attention to him in the first place.

It happened for a week and he desperately wanted to find the person responsible, but who? And how? He didn't have any friends, his teachers made fun of him, and his own mother didn't care. There weren't any clues either that could lead him towards the culprit. He was left alone in misery and question as he sought out the answers himself.

Trying to ignore the sensation had been hard and the only time it left him alone was when he went to bed. He could practically feel the gaze peeling away, leaving him alone for once after an entire day of observing. He sighed heavily in relief each and every time. Before long, he pushed it aside once the two week mark hit, figuring out that it was just gazing, never more. It obviously had no intentions on revealing itself to him.

Until the day it did.

Tsuna had been heading to school one morning when he noticed a shadow out of the corner of his eyes. Spinning around, he nearly let out a scream in distress. There, hiding in one of the neighbor's front yard, was the ghostly darkness he had seen in the pictures of the little brown covered book. It was nearly identical and there was no mistaking that creepy grin. Whimpering, he spun around and ran for it, never stopping until he was in the safe confines of the school. He ignored the glances he got from the people he passed by, unbothered by them as he knew they wouldn't care about him anyway. It was only when he got into the school entrance that he looked back.

It was still there.

The shadow creature had followed along like nothing had happened. No one else seemed to notice it, walking by as if it was invisible. It was still grinning, still looking at him with those large white eyes, and stood above his fellow classmates by a foot and a half in height. It was like a child had scribbled the being into existence by the way the edges around the creature flickered. Paling and looking sick to his stomach, he ran once more.

It never left him.

The creature followed him to class, standing in the background, and Tsuna would glance back momentarily before snapping back to the front. He could just feel the evil radiating from the being and he was reminded of the cult book he had found. Darkness. This happened because of the cursed book, right? Because he took it home and read it. Because he couldn't control his curiosity of the unknown. He wanted to cry. If only he hadn't found it, if only he had pushed it aside, if only his clumsiness wasn't so bad. However, there wasn't any way to fix the past. He was trapped because of his decisions and he had to deal with it all alone.

Still, the creature just remained there, never really moving any closer than what was necessary. This time, it did leave him alone more often as if it was consciously aware of when its presence was inappropriate.

It just watched, observing and examining him. It was just like last time when it was just gazing, except now physically there to be seen.

The bullying didn't help with his issues. Kensuke Mochida had taken great pleasure in making his life a living hell since the first time they had met. Many times, his book bag would go missing, only to be returned dirtied or found in either the pool or dumpster. His desk would be written all over with permanent marker, details relating to his stupidity, and even cursing him out. The laughter and remarks against him made Tsuna tilt his head downward to hurry by, wanting to escape before anything got dreadful. However, the most frightening was when the black haired teen physically attacked him and over time, the attacks escalated. It was like Mochida was purposefully searching him out for a confrontation just to torment him as a stress relief for the day or because he wanted to see someone suffer. He would come back home covered in bruises and cuts, hiding each and every one of them carefully from his mother, who would just get upset at seeing them. The bullying had gone on long before he found the book, only finding said item because he had been chased by Mochida to that very shine that changed his life.

Things oddly had a tendency to circle around.

Two days after the creature showed itself, he got cornered by Mochida and his little gang of buddies (four in total with Mochida). It had been on his way home from school, the one time he had been distracted by his failing test papers (his fingers were clenched angrily at each as he held every one of them). He hadn't noticed the upcoming teenagers trailing behind him until it was too late.

When he had been grabbed from behind by the hair and yanked into a closed off alleyway, he knew he was in trouble. He knew he would get it and he definitely did. Beaten, bleeding all over his clothes and the floor, he coughed as he curled up on himself to protect his insides. He was certain he had suffered a fractured wrist as well as an ankle by the way it was all swollen at the edges and his head was aching from the forceful tugs on his hair.

He hated them all. Hated. Them.

The last straw that finally broke him was when one of the boys yanked his head back by the hair once more, forcing his body into an awkward sitting position, and made him involuntary gaze up at the sky. He sneered, both in anger and in pain. Everything hurt.

Why? What had he ever done to deserve such a fate? To deserve such harsh bullying.

It wasn't fair.

"Looks like Dame-Tsuna needs a bath!" Mochida's laughter echoed in his ear and the alleyway, sending a shiver down the brunet's spine. "And I know the perfect liquid to use!"

There was a snap as a can was opened and some sizzling following right afterwards. Tsuna managed to catch a glimpse of the item, a coke, and glared at the four teens the best he could, which wasn't much considering his position. Laughter continued, blending into one, and Tsuna could do nothing but listen in misery as he knew what would happen next. His body was too weak to put up much of a resistance, his struggling taken care of by the other two teens at his sides. Mochida stepped closer, grinning evilly and holding the can above his head.

Tsuna hated them, all of them.

He wished they were dead.

He prayed, wished, desired, whatever it was, with all his heart that they were gone.

He wanted them to suffer, to pay for all they have done to him, to burn.

To suffer in absolute misery.

The can tilted and he was burned as the liquid poured over his face, drenching his clothes more so than before. He let out some yelps, still trying to struggle, but nothing worked. Some of it slipped into his mouth and nose and he gagged, coughing to get it out. As he opened his mouth a couple of times to do so, Mochida made it his purpose to take advantage of the opening.

By the time it ended, Tsuna was shoved to the side and kicked a few more times before being spat on. They finally left once they had their fill for the day, leaving the brunet on the ground, stone cold in despair. Once they were out of the alleyway, Tsuna finally broke down.

He cried.

And cried.

And cried.

Why?

Why?

"Pray to me, child."

Tsuna's honey-colored eyes snapped up towards the entrance. He froze, ignoring the sensation of his tears falling down his face, and simply stared at the creature that had been following him ever since it appeared. It simply stood at the entrance, its shadow sliding across the ground until it reached him on the floor. The grin remained.

In all honesty, Tsuna had barely even registered what the creature had spoken in the first place. His mind was still processing that the other could actually speak at all.

"Pray to me and grant me a sacrifice." The creature spoke once more. Its voice was male. The tone was calm, but Tsuna could register that there was a strain within it, like it wanted to act on something but couldn't. "And I shall grant you your desire."

Tsuna shivered as a cold breeze came bustling into the space, the soaked clothes not helping.

The creature stepped forward, his movements absolutely silent. "You want to see those boys suffer like you have."

Another step.

"You want them to be as miserable as they made you feel."

Another step.

"To feel despair."

Step.

"To feel pain."

Step.

"To suffer."

The monster stood before him and bended down at the waist, legs perfectly straight. Their faces were mere inches apart and even then, all Tsuna could see was the blackness and those white eyes and smile.

"You want them to Die, don't you?"

Tsuna quivered into place, his legs and arms feeling like Jell-O. He couldn't speak, too afraid to do so.

The creature chuckled, never pulling back. "I can do that for you, but I require a sacrifice. Grant me that and I shall fulfill that desire."

The brunet remained quiet for a little bit longer, his mind speeding through multiple thoughts. Death...This is a God...A God of Demise, Destruction, and...Death. His mind reflected back to the boys that had tormented him, back to his miserable life, back to this retched town of Namimori.

The choice was obvious.

He momentarily grinded his teeth together before answering "What must I do?" His face was contorted into anger. He wanted this.

He wanted this.

He needed this.

The grin grew wider, if that was even possible. "Offer your blood. Stab yourself to show the mark of our deal. That shall be sufficient for the time being."

Without any hesitation, Tsuna glanced around the area for something sharp. With a small reflection from the sunlight that was reflecting off the passing cars beyond the alleyway, he spotted broken pieces of glass. Crawling over, ignoring the pains in his body, he grasped it into his right hand and peered over it carefully. It looked like it had been broken off quite recently, probably before the incident, the insides still clean. The rest of the bottle was near the side, the un-evaporated fluids resting within that hadn't been spilled out from the cracks. Honey-colored eyes gazed down at the jagged end of the blade, almost in the shape of a triangle, with the bottom obviously more pointed. Getting up into a sitting position, he angled the blade downwards towards his left hand. His eyes showed a slight flash of hesitation and peered up to the creature once more.

He was going to stab himself. He was going to go it for revenge.

The creature chuckled, "Oh go on, child. I'm waiting."

Taking a deep breath, Tsuna plunged the blade into his hand and screamed soon after. It burns! It burns! Tsuna's tears began to well up once more at the excruciating pain, still screaming out his lungs. The creature simply watched like it found the entire situation amusing. It probably was to him. The brunet cradled the injured hand, bending forward to hide it against his body. Blood dripped off the end of his fingertips and the surrounding edges of the blade, coloring his clothes.

Once he managed to calm down, he peered down at the hand and immediately felt like he wanted to vomit. The angle was horrible, still sticking out from both ends of his hand. His body was shaking in response, the pain in his limb overriding anything he was previously suffering. Shakily grasping the top end, he took a few deep breaths and looked up towards the sky, at the creature, before pulling it out completely.

He screamed once more and the creature just continued to smile.

"Hold out the hand before you."

Among his screaming, Tsuna did as he was told. Blood was dripping down everywhere and the gaping hole in his hand didn't help. He could see bone, muscles, veins, everything and Tsuna snapped his eyes downward to keep himself from looking. A growing pool of red was collecting underneath the outstretched limb, his expression reflected off the surface. As he began to calm down, much slower this time, he eyed the puddle curiously. It had shifted, not from the droplets that were falling down but from something within. The creature chuckled darkly. The blood began to move like it was alive and had a mind of its own, slowly creeping upward in a straight line. It soon began to spread out, creating something circular in shape and the blood in the center began to retract back to create markings within. It was small in size but the image was clear to Tsuna's eyes because he had seen it before. It was the ritual symbol that belonged to the cult book. Once everything had been created perfectly, the line connecting it between the symbol and the puddle of his blood broke and tugged backwards. The circle was perfect.

"Touch it with your wounded hand and the deal shall be complete."

Tsuna sniffed, but complied, placing it down. The moment he did, the circle underneath glowed brightly, blinding him temporarily, and then the pain vanished completely. He blinked curiously. The pain, the burning sensation that was left behind, it was all gone. How? Lifting his hand up off the floor, he could immediately tell that the wound was gone and a scar was left behind in its place. Curious, he turned his hand over to the underside and stared in wonder. The symbol had been burned into his hand, like it had been tattooed perfectly, and he flexed the limb momentarily to simply watch in awe.

"The deal is now complete. I shall take care of everything." The creature rotated around and disappeared into the darkness of the buildings, leaving Tsuna alone in the alleyway. The brunet was still shaky, the adrenaline still coursing through his veins. He couldn't believe it. It just wasn't possible and yet he had done it without wavering.

He had just made a deal with a monster.

Slowly, he stood up and realized something else the moment he did so. The pain that should have come from the rest of his body was gone as well. He pulled his shirt up to see where the bullies had kicked him and though he recognized the bruises, there was nothing. He flexed his supposedly fractured ankle, nothing.

Smiling in glee, he ran home, wondering what tomorrow would bring. Luckily for him, it was the weekend.

"This just coming in, a body was found tied to the outside of a local home early this morning, now identified as Kensuke Mochida. He's a student that attends Namimori middle school. Police are suspecting of murder due to the grotesque disfiguration of the victim. We have some images of the body, please be advised on the gruesome sightings when viewing them."

Images flashed of the brutal murder of the teenager, disfigured beyond recognition. Cuts littered the body, the limbs clearly having been ripped off violently by evidence of the tears before being reattached together by some dirty pieces of string. It was obvious that the murderer had taken careful consideration on the placement of the needle, piercing the flesh deep enough to hurt. The body was crucified upside down, letting all the blood drain downward. His head was wrapped tightly with what looked like a plastic garbage bag (only ripped apart to help identify the corpse). The chest cavity had been torn open. The insides pulled out like the murderer had wanted the world to see everything within. Flies were buzzing around the corpse, the scent inviting for them despite the numerous officers attempting to keep them away.

It was clear as day that Kensuke Mochida had been tortured to his dying breath.

Tsuna stared at the screen, his eyes never leaving the images. He absorbed all the marks, all the cuts, all the stitches, everything.

And then he laughed.

It wasn't amused one, no. It was a happy with a tint of madness.

He laughed and laughed and laughed. He laughed until his throat burned in agony, until he could barely make a sound any longer, and yet he continued regardless.

He was glad that his mother had gone out for groceries so she couldn't hear him as he broke further.

"My wish came true! It really did!" Tsuna calmed down in mere chuckles, eyes wide with glee. "I can't believe it!"

"There are three more to take care of."

Tsuna snapped his head around in shock, not expecting his shadowy stalker to appear now of all times and inside his home. However, there was no fear in his eyes any longer. The brunet smiled, taking in the same expression the other always wore. "This won't...come back to haunt me, will it?"

"Of course not." The grin didn't move as he spoke and the head tilted to the side. Tsuna didn't sense any lying from the other. "How could you have done such a horrible deed when you came back home injured, under the constant surveying of your mother. The murder happened late last night. You were having dinner at that time." The figure stepped around, heading towards the TV, and outstretched his hand towards the brutal images. "And the rest of the four will follow soon after. I require time though and to, perhaps, take care of some others in this town. I want to make sure that there's no possible connection to you. Let the people of Namimori feel fear of their own impending doom and downfall."

Tsuna felt his face sliding upward to match the monster's grin. He could watch all his bullies suffer, make them feel exactly how he felt all this time, and it would be glorious.

The creature peered down at the screen as if gazing over his handy work before looking right back up. "Listen closely, boy." That got Tsuna's attention. "I am known as Sinister, a God compared to you, mortal, yet also a demon. Worship me and give me the sacrifices I request and I shall fulfill your requests as long as they interest me."

The teenager stared in wonder, eyes wide.

"However, do not get above yourself or I will bring about your downfall, boy." The creature stepped away from the TV, moving closer. He bent down before the brunet. "You understand that, Sawada Tsunayoshi?"

The grin got wider.

Tsuna smiled in return. "Understood~"

This will remain mostly as a one-shot unless I feel like adding 2-3 more chapters, max 4 in total. That will depend on how much people like this. If not, I'll leave alone. If you have time, to read 'Out of Place' (which is a new story) and 'The Unexplainable' as well which includes Sin/Sinister.

Before anyone asks, for the timeline on this one, I don't really have an idea honestly as it will never go into those details.

Don't forget to review on your way out. Thanks!
