Diabolik 🩸

Stay safe!!

Yui had never had many friends as a child and so had never been able to enjoy activities that one would typically do with friends. Whether that was because of her own shy nature or her father’s position in the Church, she couldn’t say.

So when Kou had coyly asked her one afternoon if she was busy, and if not, would she like to build something with him, Yui had not been able to resist. Kou Mukami was a rollercoaster of emotions and volatile at the best of times, but childish impulses had won over level-headedness for once.

They’d stretched their combined bedding over some tables in a spare room, using chairs and boxes to expand their fort. Kou had bought spare sheets and as many pillows as he could carry, and it took over an hour but eventually he was happy with their fort. Yui was breathless with excitement and followed Kou when he disappeared through the entrance.

“This is nice.” she shyly said, reclining on the mountain of pillows Kou had organised.

“Do you know why I wanted to do this?” Kou asked, lying so close to her that his cold skin brushed hers. His eyes locked into her face and didn’t move, awaiting her answer.

“I-,” Yui swallowed, subconsciously bringing her hands up to her throat, “I don’t.”

“My brothers are in the habit of interrupting our time together, Kitty,” Kou was more than happy to explain, leaning in until his breath caressed her lips, “and I thought it would be a good idea to get away from it for a bit. You know, for some uninterrupted time.”

Yui swallowed again, her thighs clenching together. Kou was the most forward out of the Mukami brothers, and lately their time together had included a lot of groping and kissing. Not that she minded, it was only that she thought she should.

Kou’s cold hand landed on Yui’s upper thigh and squeezed, bringing her out of her musings and drawing attention to the bulge in his trousers.

“Strip.” he left no room for arguments. “Now.”

Yui scrambled to obey, shedding clothing until she was bare and shivering. Kou followed suit, shoving their clothes out of the way and dragging Yui into his lap.

Yui whimpered when Kou’s fingers went directly to her clit, drawing patterns with expertise that made her quite jealous. He pinched her left nipple with his free hand, eyes fixated on her face.

“That’s what I like about you, Kitty,” his voice was raspy and it went straight to her core, “I don’t have to do much to get you riled up and wanting.”

As if to prove his point, Kou slid a finger into Yui, curling it just right. Yui cried out, her back arching instinctively, her core searching out the hard length of Kou’s cock.

It was surprisingly warm, and Yui found herself shamelessly rubbing herself on it, gasping at the way the head caught her clit with each smooth slide. Kou watched with fascination at the arousal she left on his cock before he stopped her movement.

“I should prepare you,” he said, though he seemed to be talking to himself, “but I know you like a little pain, don’t you, Kitty?”

Yui’s cheeks flushed and she flinched when he pinched her clit, a smirk on his lips. Before she could argue, he lifted her up and slid her down onto his cock in one smooth movement.

Yui cried out at the unexpected pain, wriggling in Kou’s lap. It lasted for only a moment and quickly gave way to pleasure as Kou fucked up into her willing body, the wet slap making her cheeks flush red. Kou’s hands on her hips encouraged Yui to meet his movements and she found herself meeting him halfway, grinding herself down on his cock, chasing her relief.

She wasn’t sure how long it went on, and each time she thought she might cum, Kou slowed down until the feeling receeded. Just when she thought she might actually cry, she looked down. Kou’s face was screwed up in concentration, and his neck and upper chest were flushed red. He was looking at the place they were joined, and when his tongue darted out to wet his lips, Yui’s body seized and she came harder than she thought possible.

“Not yet,” Kou spoke through gritted teeth and manoeuvred her until she was face down in the pillows. “Not yet, Kitty.”

It took a while to come to some sort of agreement, but eventually they did it.

Yuma and Ruki had fallen hard and fast for Yui Komori, and neither was willing to loose her to the other.

“Don’t make me choose,” Yui had cried. “I can’t do that to you. You’re brothers!”

That was true. They’d been there for eachother when no one else was. They’d relearned themselves as vampires, battled Founders and won, battled spoiled vampire princes and come out victorious. But if they fought each other, there would be no true winner.

“We won’t make you choose,” they’d said, “as long as you don’t make us choose either.”

It had taken a little longer to figure things out, but now the relationship was fruitful and smooth. They were hers, and she was theirs.

Looking down at her, nestled in Yuma’s ridiculously large arms, Ruki could feel only content. It was perfect, really.

Yuma was very much a physical person, whereas Ruki could be more private at times, so there was always someone there for Yui’s physical needs. Hugs, kisses, unintentional touches; Yuma provided it all.

Ruki was excellent for Yui’s (and Yuma’s) emotional needs. She hadn’t admitted it yet but this was the most at ease Yui had felt in months.

Cracking open her eyes, Yui stared fondly at Ruki before brushing her fingers through Yuma’s hair.

Despite the tumultuous relationship between Reiji and Shuu Sakamaki, it hadn’t taken them long to decided that they both needed to come together for this one particular task.

Taking care of you.

Neither of them would admit it, but they were essentially in a relationship with you. They enjoyed spending time with you, would actively seek you out, would give you gifts and both could listen to you talk all day. One thing they could not put up with, however, was the dangerous situations you seemed to have a taste for putting yourself in. Such as interacting with that Mukami beast, Yuma.

Appearing before you, Shuu snagged your arm and carted you off down the corridor. He ignored your shouts of protest and wriggling and continued on, his patience wearing thinner with every second. 

He found Reiji in the economics room, empty other than the three of you, and thrust you into his chest. “She was talking with that Mukami idiot. Again.”

Pushing his glasses up the bridge of his nose, Reiji sighed deeply. “We have discussed this before, Y/N, and you continue to disobey. Do you not think we will follow through with your punishments? Is that it? It seems it is no longer appropriate for you to continue your education at school; I will tutor you at home and Shuu can offer you assistance with music and poetry.”

“Hey!” you were quick to disagree. “That’s not fair at all-”

“It is for your own safety,” Shuu interjected, gripping your trembling chin between his thumb and forefinger. “You seem to forget that we know best.”

“Oh, what does it matter,” you almost snarled, shoving Shuu’s hands away. “I’m only a Bride, anyway, I’ll die soon.”

Shuu snatched your face into his hands, his eyes looking crazed and glinting in the sparse light. “You seem to forget,” he repeated, “that I fucking need you more than I need to breathe.”

Blood sharing was a passionate, hot and all-consuming experience. It required trust and a bond, something that you had never imagined possible with the Sakamaki triplets. Kanato was too childish, Laito was too vulgar and Ayato was quick to loose his temper. You were too mature, too knowing, to have an easy relationship with them.

Ayato loved Yui, and he knew it. It took him a long time to realize and longer then come to terms with it, but seeing Yui’s sweet face everyday had only quickened the process. Oh, he had it bad.

When Yui had first come to live with him and his brothers, he had found her as annoying as all the brides before her. But with her patient and caring nature, it hadn’t taken him long to realize his annoyance had turned into something very different over a number of months.

He hadn’t told her and likely never would, but he’d come to physical blows with Laito the other week. Laito had been making his usual vulgar comments about Yui, and seemed as if he would act on them, and Ayato snapped like a rubber band. Laito had broken Ayato’s nose but Ayato broke his arm so he counted that as a win. 

Thank you so much, hope you enjoy x

It had taken years for Reiji to develop his refined, gentlemanly personality. It had been quiet the challenge, what with him living in a house full of unintelligent and unrefined siblings, and it was defiance against his very being as a vampire, but he managed. 

Sometimes things threatened to knock him a little, like picking up after Laito, or Kanato’s howling or Subaru’s blatant disrespect. These days Shuu did little to knock his mood, and Reiji’s constant biting words only came from habit. Shuu was essentially an inanimate object now, and Reiji found it all too easy to ignore him.

Then that sacrificial bride arrived. Yui Komori had challenged every aspect of his and his brother’s beings. She had taken their insides, twisted them and put something different back. It gave Reiji great satisfaction to know that, out of all his brothers, she had ultimately chosen him. She was his. 

Yet she still found time to spare for Shuu.

Reiji peered down the corridor, his face a careful mask of indifference. Yui was trying to pull Shuu up, likely to escort him to his room, and unsurprisingly he was not cooperating in the slightest. This did not stop her, and she continued to put her tiny hands all over him, even going to far as to bend down and try to pry open his eyes. Yui didn’t see it, but Shuu’s lips were upturned in a slight smirk.

Reiji’s mask cracked.

“What, exactly, is going on?” he sharply said, appearing directly behind Yui.

“I-I know Shuu sleeping outside of his rooms really annoys you, so I thought I should try to move him for you.”

“Whilst you possess good intentions, it seems you possess no intelligence.” he adjusted his glasses on his nose. “I believe we have been over this repeatedly. You are my property, and I have forbidden you to interact on any level with this ingrate, yet you chose to disobey me.”

“N-no I just-”

“Be quiet,” Reiji snapped, his hands trembling ever so slightly in rage. “This is not up for discussion, it is clear as day what was happening. You are to come with me and we will discuss a suitable punishment.”

Yandere Shuu Headcanons

Warning: NSFW

Laito paused as he glanced over his handwork on the bed. You were intricately tied up in a way that made your muscles burn and your head was yanked back so far that you could feel your pulse hammering.

Welcome :)

The Mukami mansion was wrapped in a tense silence. Yui swore the only sound she could hear was that of her own heart which was pounding viciously as she clutched her small hands to her chest.

Yuma was sat with her in the empty living room, staring blankly off into the distance. Around them was smashed glass, broken furniture and splatters of blood that glinted in the light. 

The Mukami and Sakamaki brothers had put aside their differences to defeat the wolves but the moment the last wolf had been killed, Ayato had made an attempt to snatch Yui and whisk her off to the Sakamaki mansion. And now, as usual, Yui was left to deal with the consequences of this failed abduction.

Yuma suddenly sat forward, snapping his gaze to Yui. He looked her up and down, taking in her dishevelled appearance before grinning wildly.

“It’s a good thing you’re so committed to me, isn’t it?”

Yui didn’t hesitate, having learned her lesson by now. “Yes.”

“Good thing that Ayato is so fucking stupid, too.” he continued, standing up and grabbing Yui’s arm, pulling her into his broad chest. “The next time he touches what’s mine, I’ll cut his fucking arm off.”

Thank you so much :)

Laito had always thought that he enjoyed cruelty, giving and receiving. It had taken him a while but he now realised that it wasn't true, and all these years he had only been justifying the suffering he had endured at the hands of his own mother.

Even now he didn’t like to talk about it, but looking at the blond girl who lay next to him he felt the urge to open up. To spill everything, come clean. All so he could be a better person for her. Hell, he’d even go to church if she asked.

Biting back the urge to make some crude remark, Laito turned on his side to observe Yui. She was deeply engrossed in her book so didn’t notice, and the pleasant blush that usually appeared did not. He was almost glad as it gave him the opportunity to openly study her, the girl who had flipped his life upside down in a matter of months.

Apparently kindness and perseverance really were the key to everything. Laito knew that if it had been anyone else it wouldn’t be the same. Countless girls before Yui had urged him to change and it had resulted in their deaths. Torturous, slow deaths. But Yui Komori was different.

Soft eyes flickered to his, and that familiar blush spread across high cheekbones as she asked what he was staring at. Laito felt a genuine smile tugging at the edge of his lips.

Despite the fact that Yuma was a vampire, Yui was sure his strength was well above average even then. Especially now, as she struggled fruitlessly against him, she knew that even if Ruki or someone decided to help her they would have trouble pulling the huge vampire off of her.

Yuma laughed wildly, “You’re so cute when you’re struggling. We should do this more often.”

“Please, please just get off of me.”

Yuma snorted, “What, so you can run off to one of my brothers? Because you like them more than you like me, right?”

Yui stopped struggling, sensing the dangerous direction this was going in. “N-no, I wouldn’t do that. I like you.”

Shu: The two of you are out in public when your long skirt gets torn, leaving a long slit up the side of your thigh. Shu’s brows shoot up and he mutters, “I knew you were lewd but lets keep this side of you out of the public eye.”

Reiji: The two of you were just finishing up your first class of the day and when you rise from your desk something catches on your tights, leaving a long tear leading from the outside of your thigh all the way to the inside. Reiji’s eyes widen comically and he says, “Whilst I value education, this isn’t something we can put up with for the rest of the day. Come with me, we’re going home and fixing this.”

Ayato: You’re late for class (thanks to Ayato) and running through the corridors when several of the buttons on your shirt choose that moment to tear off. It leaves you with a huge gape in your shirt revealing almost everything. Ayato’s jaw drops and he drags you off into a nearby supply cupboard. “You shouldn’t show that part of yourself to anyone else, ‘kay?”

Kanato: You’re helping him sort some shelves in his room when your shirt rips from your armpit all the way to the bottom, exposing a large patch of skin. Kanato cements himself to your side, his face resting against the bared skin. “This side of you is all mine, you know? I just want to kiss it all over...”

Laito: He’s watching you play volleyball when your shorts decide to rip all the way up your thigh and expose your panties. One minute you’re standing with the others, the next you’re pinned onto the locker room benches. “I know I joke a lot, but this part of you should only be show to me, right Little Bitch?”

No problem :)

Shu and Reiji, the bane of Yui’s life. On that particular night, around two weeks ago, she’d chosen to belong to Shu thinking that she’d have to deal less with the others. And she’d been right. Subaru, Laito, Kanato and Ayato were practically none existent in her life. Reiji however? She had to put up with him every day.

Snide comments, scornful looks and now punishments. With a wince Yui rubbed tentatively at her sore wrists; she’d never look at a ruler the same way ever again.

She ambled down the corridor, heading towards her room when she same a large figure propped up on the ground outside of her door. She paled instantly- it was Shu. A.K.A the reason she’d just been punished.

It was no secret that Reiji despised Shu, but she’d been surprised to see that he’d completely ignore the rules and put his hands on her all because of the choice she’d made. Quietly Yui continued to approach her room, holding her breath once she got within 5 feet of the vampire.

When she tried to push open her door, an ice cold hand secured itself around her wrist and yanked her backwards. Yui struggled fruitlessly in Shu’s lap but he pinned her arms to her side and yanked her back against his chest.

“He touched you, didn’t he?” Shu muttered, peering down at Yui’s wrists. “Fucking weirdo. He’s always been jealous of me.”

“Yes,” Yui continued to struggle, “So can you please let go? He only punished me because I chose you so if you leave me alone-”

“I’ll do whatever the fuck I want to you, got it?” Shu snapped, sinking his fangs deep into the flesh of Yui’s neck. He growled deeply as he drank, his hands wandering over her chest.
