I wanted to delete this oneshot as well because it's so long and such nonsense ( like the previous two ), but then I decided to let it remain since i found the yandere-ness passable. Oh well. . .

Yaaay. I'm back with another trashy oneshot which would have the same characters as the focus with the one where Yamaguchi dies. This time, as I have given as a clue on the theory trash, this oneshot has nothing but jealousy, insanity, stab, stab, stab, laugh. You've probably already guessed what kind of person the freckled angel would be in this chapter, so if you are against yandere, get the heck out. Haha. Yeah. Don't tell me to change the pairing unless you have a better idea and because Yamaguchi Tadashi is seriously my favorite character so sssh. Might contain a lot of irritating dialouges because that's how yanderes think.

⚫⚫⚫

No. Impossible. This was not happening. Not in a million centuries was this ever happening.

The pinch server continued to stare with empty eyes as the scene unfolded infront of him. He couldn't believe it. He had been betrayed, he had been left behind, left to rot because a whore seduced his precious Tsukki. He had been thrown away and left to fend for himself because a succubus with no sense of justice came from the pits of Hell to the surface of the Earth in order to steal the most perfect human in all of the population.

His place had been taken. The spot where he would usually stand, right beside the middle blocker while they talked, while they walked, watched, laughed, shared stories, while they did everything perfect for him. The place where he would aid his best friend in times of need, the spot where he would do for his best friend what he doesn't want to, the very place where he was supposed to be standing right now, listening to Tsukishima's complaints and hearing his heartbeats.

In his hand, the water bottle which he was supposed to give, fell to the floor with a thud as more and more horrifying thoughts started flooding his mind. He did everything for the blonde, he kept quiet, he kept his distance, he shut his mouth up when told to, he shouldered his problems, he didn't talk about unnecessary and unwanted things, he allowed himself to be dragged around or be a servant to his best friend just because he wanted to be his friend for so long, he admired him so much.

But he had been replaced. By a woman whom they didn't even know so well. He liked the fact that Kei was happy... but not the one which told him it wasn't with him. His best friend was happy in the grasp of another person which wasn't him, his best friend was having fun socializing with a dummy who will only act as a person who would drag him down in the end. The female would only surely be acting as a Damsel in Distress, she would surely be the cause of everything to fall apart.

She was the beginning of an end.

An embodiment of curses and lies, she didn't have the right to cling to Tsukishima like that. As everyone crowded around the two of them, asking them about how they had met and how they had come to the conclusion that they would be together from a certain day, Yamaguchi couldn't help but feel irritated. Disgusted. Mad. Depressed. He was brimming, overflowing with hate he was sure was never to go away.

The sound of the water bottle falling to the floor didn't have any impact on the others' ears as they had been flapping their mouths around in an annoying fashion, sending noise all over the place. Noise. Noise, noise, noise, oh how he hated noise. They were flocking over to his best friend, making him feel surely uncomfortable. If that was so, he would have a chance to slip into the scene and interrupt.

But at the moment he caught sight of the latter's expression, it had said otherwise. He was smiling. Genuinely. Happily. He wasn't being sarcastic or mocking or any of that. He was seriously damn joyous, not showing a hint of being irritated at all or even not being able to tolerate anymore of this ruckus. In the arms of his new girlfriend, he was not feeling awful at all. In fact, this was the happiest Yamaguchi has ever seen him in. His aura was very light, full of peace and authentic appreciation.

Twenty meters away from him lay a cluster of people who were doting over his best friend and the female student. Nothing made his blood boil more than this.

Tadashi picked up the fallen bottle and looked at it for a moment before shoving it into his bag. Then again, he remembered how dirty it must already have been because it fell when he saw a nauseating sight, and because it probably landed on a spot where the bitch had stepped on atleast once. Just thinking of the virus which had been scattering inside of his bag made him shiver in ultimate disgust.

He picked the plastic bottle up and immediately put it into the trashcan. He looked back to see that no one noticed him, so he tried to get past the wave of annoying classmates and upperclassmen and maybe for his beloved Tsukki to notice him. He sneaked through the circle and walked stealthily, not knowing whether to want to catch attention or not. Even so, as he was about to exit the door, he heard a voice which could only belong to one person.

"What the hell are you doing, Yamaguchi?" Tsukishima's voice came from behind him, causing him to freeze up and grow really, really happy, almost forgetting about the woman near his best friend. He turned around and answered with a lie, just to make the middle blocker not worry, reassured about his safety.
"Ah, I'm going to practice my serves a little bit more, Tsukki. Would you like to--"
"I see. Then, go ahead without me if you need to."
"N-not at all. I'm not in any rush. I will wait! Are you free this afternoon then?"

Suddenly, one of the most shitty voices he had ever heard in his entire life emerged from an overly red mouth, overly red from dabbing of too much cosmetics called the lipstick. The speaker also had a strong perfume sprayed all over her; the scent of prostitution lingering in the air as she skipped towards Yamaguchi in a manner which made him want to bang her face into a volleyball with spikes repeatedly. He couldn't tolerate this kind of thing, especially due to the circumstances. Especially because Tsukishima was involved, his long-known friend, his best friend, his companion, his Tsukki.

"So you're Yamaguchi? Kei has told me a lot about you!"
Kei? Kei? She was calling him by his first name now? How much of a bitch can one person be? She just knew him probably for less than a month and yet she was already being all familiar with him?

But then, saying that was an insult to Tsukishima. By saying that he started dating a girl he barely knew, it was as if he was pointing out that his best friend was someone who rushed things with other people in order to gain rank, authority or place, even. But it wasn't true because Tsukishima was a smart person, a calm person, a cool guy who had been his friend all these years.

At that instant, Yamaguchi knew what had happened. She tricked him. Lied to him. Maybe even brainwashed him! Deceptive foxes weren't rare these days, and they especially wouldn't let someone as spectacular as the middle blocker pass without laying a finger on him. Yes, that was it. She was evil, corrupted... and he knew what he had to do.

He had to eradicate the darkness, to slay the injustice that was being born and raised to live freely among the innocents. He had to do it. He had to kill her. For the safety of Tsukki, for the good of Tsukki, for the sake of Tsukki because that was how things happened all the time. He did everything for Tsukki no matter what it was due to the fact that he had nothing better to do, nothing more precious to treasure. He did want to see his best friend happy, but it should be with him.

Nervously and trying so hard to stifle the anger that lurked within the depths of his mind, Yamaguchi faced the girl and smiled at her nicely.
"Ah, yes. That would be me. Treasure Tsukki until the last moments of your life, okay?" Yes, the last moments of her life. The last moments which were coming soon... very, very soon.

She had said something, but Tadashi was too annoyed to try and listen as he turned around and started jogging towards his house. But then, why would he go there? Shouldn't he stay here and watch the girl's every movement, every step, every breath and every bat of an eyelash? He should stay on watch and guard the surroundings so as to make sure that the blonde would be safe.

Seeing this, he moved back and headed towards the rooftop where he could get a great view of everything from down below the tall building.

His eyes darted around the grounds as he scanned the area for any signs of the life-ruiner, of the bond-cutter, of the attention-seeker and of the ultimate whore. It was funny how much negative qualities one could even have in her. That just showed how much of an abomination she was exactly. That just gave Yamaguchi more of a reason to detest her from the pits of his feelings. As he leaned against the wire that kept the border between life and death, the edge of the building, in check, he sighed at the thought of having to really do this.

Then smirked. At the thought of having to do this again.

It wasn't a mystery that no one noticed what he had done a few years back. It wasn't such a big change in the world when a few people discovered that he was insanely inlove with someone who loved a different person. Until now, it was still him, the only one who managed to make his world a better place all on his own, in his own perfect ways, the most perfect human being in all of Earth that 'human' was a very disgusting word to describe him. Tsukishima, to Yamaguchi, was a God who had fallen and forced to live among the mortals he once ruled.

He was a fallen God. He was one of a kind. Tsukishima was to be his. This thought was what drove him to do it three years ago, back then when they mocked him for having 'lied' about his brother being the ace of Karasuno. He was innocent, but they mocked him, laughed at him, pointed at him with defiled hands and dirtied skin. A God wasn't supposed to be treated that way because they were just lowly humans, though Tadashi saw himself aiming for the seat on the right side. In due time, he was sure Tsukishima would acknowledge him after he slayed the little girl admiring him from afar.

He made it look like an accident, he was sure to hide the details. Luckily enough, he was too smart for the Police. They didn't catch him. They were lame.

And now, he would have to do it another time although he was tired of hiding bodies. He would rather let the corpse hang on display in plain sight than bury it somewhere deep in the mountain forests. Yes, that's right. He would give them all to Tsukki, he would send spectacular decorations and live paintings to him. He would do anything just to have his precious Tsukki to appreciate all of the things he had been doing and promote him to a higher rank. He was doing this all for Tsukki, all for Tsukki, everything he would be willing to give and take for Tsukki. He would kill for Tsukki. He would die for Tsukki. Just so he would have his heart. Tsukki's heart.

As he thought of these things, Yamaguchi felt a shiver run down his spine. It wasn't out of discomfort or caution, but it was out of excitement. He was too excited to feel the struggling person under his strength he didn't dare show anyone else in fear that it might blow his cover. He was too excited to feel the blade running through solid flesh and turn it into charred meat. He was too excited to feel the pain in his ears from all the screaming he would hear.

Even so, he would have to plan this all out carefully so as not to have his perfect dream get ruined. He wondered what kind of method was the best to use for a bitch who stole his God away from him. As much as he wanted to shove his arm through her throat and grab her intestines before turning her inside-out, hanging her by those organs on a branch so he could use her as a swing, that would splotch so much filth on his skin that needed to be clean and pure in order to be accepted into Tsukki's kingdom.

He had to stay as pure and clean as possible. He had to make this kill a sacred ceremony wherein the lady would still be pretty, not grotesque-looking even after her passing. He had a defense; it wasn't murder. He was simply making a sacred ritual, a holy passage. That girl probably was one of Tsukki's favorites at the moment, and because of that, he would have to offer her to him.

Offer her to him in the best state possible, slay the succubus without staining her entire body with red, red blood so that Tsukki would see he was fooled. Once something was covered with something, their true nature would never show up, and he would have to leave the girl naked in mind and soul in order to deliver her in the truest way, in her most genuine state. It was sacred, after all! He noticed that he had already arrived at his home, and that he was collapsed right infront of the gate.

People looked at him, but he didn't mind. He acted as if he was just plainly exhausted from all of his day's activities. He might have looked like a bread shuttle, so maybe it was all normal for someone like him to be so tired after a day at school. Several seconds passed and he managed to catch his breath. He wasn't the best actor, but he had experience.

He was acting everyday, after all.

He pretended to be hurt from some beatings he 'received' from the thugs at school who 'kicked him and punched him' because he brought the wrong food. He smiled at the little girl who approached him a few feet who seemed concerned, then entered his house. As soon as he closed the door shut behind him, he stripped everything off and ran to the shower. Before he would plan the sacred ceremony, he needed to be clean, pure, free of filth.

He needed to be in perfect condition, a functioning brain started with being refreshed. As soon as he finished bathing, he slipped into a change of clothes and locked himself inside his room, thinking. Thinking. Racking his brain for what he could possibly do. After a while of meditation, he finally got it. He would have to wait for two more days before he could do it. He would wait for the weekend. He would wait for the best time possible where he'd have all the time in the world. He finished all of his homeworks due next week. He got everything sorted out. His fridge still had food; he didn't have to go grocery shopping this Saturday. Club practice was out.

Things have never been this perfect.

"Kei, I'm sorry. I know this is too far - fetched for you, but--"
"Yes, I already know about it. She's been murdered in her house. The cops found her body twelve hours ago."

Akiteru could do nothing but stare at his younger brother who sat on his desk, reading his notes. His headphones that he were previously wearing now hung on his neck as he talked to him. His room was clean as ever, not a trace of depression in sight. He didn't seem to be down. He didn't look like he was affected at all. He was just there, not showing a reaction about the death of his girlfriend. He sat there, skimming over his notes like the news was just as normal as hearing of a human eating breakfast, lunch and dinner.

Even so, Akiteru knew he was just hiding the pang of sadness that was forcing itself out of his brain. Akiteru knew that Kei couldn't believe anything that was reported just yet. He knew that his brother was still trying to coat his head around the fact that the person he had only started hanging out with a week ago was already dead. He tried to speak, but as if Kei had eyes on the back of his head, he stopped him from bickering further.

"We have a long quiz for tomorrow on physics. To be honest, this is probably my worst subject next to mathematics, so if you wouldn't mind, please leave me alone." He spoke with so much certainty that one would think he was very much being honest. A part of him was, actually, but he just really wanted to be alone right now. To be alone.

Having been left with no choice and knowing he couldn't get a go against his brother's straightforward remarks, Akiteru forced a tired smile and left a message before leaving the room. "I see. Good luck with your test." He let himself slip through the door and continued, then exited completely. "Just remember... it's not your fault." He let it be barely audible as a whisper, but the silence allowed his voice to reach Kei's ears. As the lock clicked, he tossed his notebook away and banged both fists on the table.

He didn't know what to do, nor did he let himself think about what to say. All he could think about was the fact that he felt as if the loss of an innocent souls was probably because of him. He just couldn't help but feel like there was something, someone, who committed a crime because of him. The bottled water couldn't wash away the guilt that formed a lump in his throat, nor could it refresh his mind and push back the tears that threatened to flow out of his eyes. He knew he was being so stupid right now, but he also knew that he was probably at fault.

___

He had done it. It was perfect. A masterpiece. It was the most wonderful work of art he could ever have seen. His breathing was ragged as he looked at the perfection he had worked on for a whole day. He admitted; he was very lucky that this girl lived alone in her own house, away from her parents. He was lucky that the neighborhood she had dwelled in didn't seem to be so crowded. Yamaguchi grasped the glue gun on his hand as he continued to hold his laughter back. He had done it.

The girl was affixed to the wall of her pretty little bedroom like an angel in a position similar to that of the carving infront of a ship with her hands spread out around her like a letter 'T'. Her heels were glued together so as to have her feet form the same letter. Her head was tilted slightly to the left, sending her dark brown curls cascading over her shoulders. She was covered in a white, beautiful dress which he found inside her closet. The expression on her face was peaceful, as if she had been sleeping. Indeed, this was a masterpiece.

By sedating her with hallucinogenic drugs that would last for a few good hours, she would be left being able to do nothing but listen to orders. The dose was strong, and Yamaguchi had to go approach extreme measures to be able to get it, but he did, anyways. The girl cooperated quite well because of it. He made her fall asleep while he drilled holes into her heels and plugged them with some kind of putty so as to allow him to perform the next steps.

He held her against the wall and allowed her blood to get drained as he pulled the putty out of the products of the electric drill. It was a tiring activity because she was quite heavy, and that the blood got drained really slowly, but he managed. All of it was for the sacred ceremony, for the sacred Tsukki. She got lighter and lighter by every second because her bodily fluid got drained out of her, and that she died of blood loss too quickly.

Once a person would die, their heart would stop beating of course and also cease to pump blood through their veins and arteries. The organs would soon stop working, and that would take a lot of weight out of the person. Since the internal parts were no longer functioning, it would be harder for the blood to get drained out of the body by every second, but because she wasn't already killed before she was cut, the results were quite satisfactory. It wasn't probably a hundred per cent, but plasma exited her body and Yamaguchi plugged her heels once more.

Now that she was literally lifeless, he had to make her look beautiful, still. He grabbed a dress from her closet and ripped her pyjamas off before putting it on her. Searching for a makeup kit somewhere, he found one lying under the compartment in her mirror cabinet. He pulled it out and began his work. He wasn't exactly a professional in makeup, but he knew how to do it. When he was young, he would be so idle and would always observe things, so he had knowledge on everything he possibly would have known about. He didn't get to try things out because he lacked the equipment and all such as trying to play the piano, but like doing makeup, he had seen it more than a few times to be able to get his mind to remember.

When he had finally finished, the girl looked like she was still breathing because of the filled-up 'craters' in her cheeks and neck. Now to hang her.

He loaded the glue gun with high-quality super-glue sticks and slowly, slowly glued certain parts of her body to the wall. Wrists, back, legs and heels. He held her long enough against the wall in order to get the glue to dry and stick her there properly. The fact that she had lost all bodily fluids and that her organs were already as dead as her made her lighter. He fixed her hair and angled her head to the left and stepped back, admiring his work.

Now he was clutching the handle of the bucket which he had put under the body during the draining process so as not to have the red mess up everything in the perfect scenario. He was now out of the girl's house, making sure to leave the lights open. He had used lint rollers on every inch of the house and even put a full overcoat, head and all, on himself while performing the ritual. He wiped the surfaces clean just to make sure that he didn't have any fingerprints or any kind of prints all over the place.

If you asked him, it wasn't tiring. It was entertaining. He enjoyed his work so much, so much. He disposed of the bucket by throwing it inside the dumpster and smiled. Bye-bye to the ugly bitch who took his world away.

The next day at school didn't seem like his doing was a very good one for most of them. The teacher was saddened to hear that the class representative for Year 1, Class 4, has met an unfortunate accident which seemed like someone had planned it out for years. Everyone grieved for the loss of someone so important, and Tsukki wasn't being himself. Though they were afraid to ask him, they did anyway. They asked him how he felt, but he just sent them a frown which they went away upon seeing. During dismissal, he went straight home. Not even bothering to attend club practice. Not even bothering to talk to Yamaguchi.

The thought of not being able to hear Tsukki's voice or go together with him anymore sent tremors around Yamaguchi's brain. This was not possible. Not. Possible. He was supposed to be praised for the work he had done, he was supposed to be rejoicing with his Tsukki right now over the incident of a rotten succubus disappearing from their lives. He was supposed to get promoted. He was supposed to be loved. He was supposed to have taken Tsukki's heart.

He followed the blonde all the way to his house and before he reached the place, approached Kei.
"Hey, Tsukki." No response.
"Tsukki, I'm really sorry about what happened. I-I couldn't believe it either and--"
"It's fine, Yamaguchi. It's fine."
Fine? That was all? Fine? Wasn't it superb? Spectacular? Marvelous? Extreme? Beautiful? Yamaguchu froze in his place and gulped. Things weren't going according to his plans. Something messed it all up. Just something.

Could the girl have left a curse? Could she have cursed Yamaguchi?

If that was the case, he couldn't have Tsukki's heart anymore. He couldn't live with him as one anymore.

Then, if that really was what was happening... he would have to do it literally.

He persuaded Tsukishima to let him stay for the night since his mother and brother were out, anyways. They dined on Yamaguchi's cooking, which, to his disappointment, Tsukki didn't eat much from. He was really starting to get the feeling that the girl had left a curse. A curse which was because she didn't want him to look at another person. A curse which was because she hated Yamaguchi. She hated him for sure.

As they decided to settle for the night, Yamaguchi grabbed a knife from the kitchen and confronted his Tsukki, his world, his God. He stepped in front of him and allowed the blade to stay in visible light. Sensing something was off, Kei heightened his defenses and tried to speak in a calm way as possible.

"What's wrong with you, Yamaguchi?"
"No, nothing's wrong, Tsukki. In fact, everything is very, very perfect."
This was really weird. He wasn't usually like this. The tone in his voice made it seem like he wasn't himself. It was different. It was broken. It was a monster's. At that instant, he knew what had happened.

"Yamaguchi... you killed her, didn't you?"
The freckled male flinched, gripping the knife even tighter in his hand. Silence stretched across the room, only to be broken by his low giggling. It was too disturbing, much too disturbing to be comforting. Before long, he was soon laughing in an atrocious manner, though it was kind of frivolous in a way Kei couldn't determine. He laughed and laughed until his stomach started to hurt. He lifted his head and let it move to the right with a cracking sound coming from his neck, and his eyes were seriously, most definitely not his.

"No, Tsukki, I didn't kill her! How silly of you to think that. I thought you were smarter than this." There was no reply, and this made him continue speaking more gibberish. "I obviously offered her to you in the most sacred way possible!"
Surprised by the sudden change in his attitude, the blonde stepped backwards several paces and threw a remark back, losing his cool.
"Are you retarded? That was, in no way, sacred, let alone humane."
"Oh but Tsukki, she wasn't human!"
At that instant, everything came to him. He didn't need answers. He just needed the questions. Right. It was indeed his fault. All his fault.

"I... I apologize, Yama--"
In a moment, his sickening neck - cracking came again, accompanied by the same wicked laugh. He drew his head back and continued to cackle, throwing the knife at the light bulb, causing the room to be plunged in darkness. He went over to the broken pieces, picked up the blade and not caring about the shards of the bulb that dug into the soles of his feet. The object contained mercury. He was aware of that. But he didn't care. He only cared about the heart of his Tsukki.

"Nothing to apologize about, Tsukki!" Hearing that annoying nickname come out of the mouth of this monster sent chills down his spine for some reason. Tsukishima instinctively reached for the doordoorknob, but it was locked. From the outside. Yamaguchi probably locked it there before entering the house. Clever little shit. He knew that Yamaguchi was his best friend, he knew that he did this all for him, he knew what all of his reasons were. But he just couldn't bring himself to believe what he was reduced into. A monster.

As the monster stepped closer towards him, he could feel his heart racing faster and faster and faster... until he thought it was going to explode. The nervousness he felt wasn't something he could throw away. This was his best friend. Was. And he would have to go against him in order to prevent him from pursuing his plans. In order to save his life. As soon as Yamaguchi came running towards him, he prepared himself for the worst and prepared to dodge.

___

In the dark, there lay a lifless, bloodied and battered figure with a raving creature on top of it. He was repeatedly stabbing the blonde on the floor, right on the stomach. He had lost his mind. He had killed the very person he wanted to protect. He had ended the life he treasured so much. He dropped the knife and carried his weight by pressing his palms against the wooden floor of the Tsukishima household. He had really done it. He could no longer run away. He could no longer escape. He was finally his.

"I still... have to take your heart..." he picked the knife back up and cut Kei's torso open, pulling the organ out of his chest cavity. It was difficult, considering the number of blood vessels connected to it and judging by the softness of the organ, it would immediately be ruined once he pulled it by force. He cut the ones that were hard to snap, lifting it over his head and screaming out, as if praising it.

"Tsukki, Tsukki, Tsukki! I have your heart now." He hummed as he sniffed at the organ and licked it, savoring the flavor of the blood that once coursed through that image of perfection. He was the embodiment of everything absolute, of anything Godly and all things spectacular. Even though he lay without grace as his mutilated body pressed flat against the floor, he was still more beautiful than the masterpiece which Yamaguchi had created a few days ago. Was that two or three? He forgot. He didn't care. All he did care about was...

"Your heart... your heart... we shall become one, dwell in one soul and body for all eternity..." he lowered the heart to his lips. "Until the day I die. Tsukki!" With that, he sank his teeth into the raw human organ, losing what we call sanity, reasoning, and humanity to something as fickle as what he had referred to as 'love'.
