A/n: Alright, this is going to be one chapter per character for Diabolik lovers. I'll be making another one for when the Mukamki brother's come in but that won't be till later. For now I'll be going from oldest to youngest so this first one is for Shu. I don't own anything but my idea and Oc, Selena. Who is a raven haired female with gray eyes.

-Story start-

Selena was the elder adopted sister of Yui Komori, she was quieter and a lot more logical. She spent most of her time with her headphones on blocking out everything and everyone. She had seen those whom she loved die before her at a young age. She knew that once she was older it would affect her so she blocked out everyone and she became cold and distant to everyone. She didn't believe that anyone was worth her time, especially when it came to love.

She knew she was an attractive female and she denied everyone who ever came close to her mainly because she didn't want to be hurt again, she didn't want to find out that while she was with someone that they'd die. That was until she was sent to the Sakamaki mansion where she lived now with the six boys and her stupid sister. She was happy she wasn't blood related to the female otherwise she'd have to seriously get out of her comfortable zone and slap the sense into Yui.

But she wasn't so she didn't have to. She only rolled her eyes and left whenever she saw that her sister got herself trapped by one of the brothers. There was only one of the brother's that even caught Selena's attention and that was Shu. Shu would allow her to cuddle with him and at times they'd fall asleep in whatever couch Shu was sleeping on and they'd both get railed at by Reiji for being lazy and sleeping where ever they wanted.

She didn't care, she enjoyed the time she spent with him, even if she started to care for him she didn't want to fall in love with him just for him to reject her...or worse yet find out about her dark side. She sighed and closed her eyes as she lied by a tree near the house as she leaned against the bark of the tree she had her big headphones over her head which made it easier for her to block out everything until she felt someone kicking her boot. She removed one of the sides of her headphones as she looked up to see that it was Ayato who got her attention.

"Reiji wants you Weirdo." Ayato said with his arms crossed

She sighed and got up. "Fine." She said softly before she placed her headphones back on and went inside.

She knew where he usually was so she went to the first place she thought of first only to see him there. She took her headphones off only to see him glare at her.

"If you are just going to laze around the house like that good for nothing Shu then you can be a test subject for me." Reiji said seriously as he looked to her

"Whatever, its not like I really want to do anything anyways." She said with a shrug

He gave her a small cup to drink out of and she sniffed it only to smell apples. She sipped it cautiously only to feel something within her trigger her depression. Reiji watched her as her one emotionless eyes finally showed emotion, the first shown was sadness. For what reason he didn't know. He took the cup out of her hand and placed a hand on her head.

"The next time you want to be a lazy ass don't." Reiji said before he dismissed her.

She only placed her headphones on as she went to one of the empty rooms only to curled up on the couch in the room just so she could collect herself.

Shu had been looking for the girl who usually bugged the hell out of him. Even though she bugged him, she wasn't scared of him, hell she wanted to be closed to him. So each time they cuddled they'd fall asleep, he had one time given her a nickname...Cuddle bear. He only called her that though when he wanted to drink from her. Which from what he had heard from her, he was the only one she'd allow to drink from her. Which made him question why was he so special that she'd reject his younger brothers. But he never voiced it, it was too bothersome to him. Especially when he had started to harbor feelings for the girl.

He didn't understand why or how he did, it just happened one night when they were cuddling. She gotten too close to him and with the full moon that was close affect him he couldn't hold himself back from her. He had hoped that she would be frightened away but she wasn't, she had made it so he wouldn't ever get the crazy blood lust that his brother's would usually get. She had made it clear to him that she would be there for him and only him. Which then made him question her, what did she feel for him? Did she feel the same or was he just thinking too much like Reiji?

Speaking of his younger brother, he had smelled the scent of Selena from the lab that he was usually in 99% of the time. He wondered why Selena was in there for if she hated Reiji, so he went to the closest empty room only to see her curled up on the couch. He lied beside her pulling her into him as he did so. He felt her body stiffen as her body touched his, he wanted to question her again but again he didn't. It was too troublesome and he didn't like things that were so troublesome so he kept quiet. He only wrapped his arm around her tightly and kept his eyes closed as he felt her turn herself around and hold on to his shirt like she usually did.

He knew she had an emotional problem, he knew that she had been hiding it from him, he wasn't stupid he just didn't like it when Reiji called him out to be Lazy and good for nothing when he knew nothing of what he had dealt with. Always being pressured, always having the heat of dealing with their mother. So when she got killed he stayed quiet and started to push everyone away from him, that was until he met Selena who happened to have found her way into his undead heart.

He couldn't really place it but he didn't like it one bit when he lied alone, because of all of the times that he had slept with her in his arms he couldn't sleep now without thinking about her, how she didn't protest to him just cuddling with her or the times that he would just bite her neck without warning. He closed his eyes and kept her close to him as he felt her body shaking slightly which was odd. He opened one of his eyes to see what was wrong with her.

Selena didn't want to be around Shu which was why she tried her best to stay away from him. She didn't want to deal with her feelings while being around him. She knew that he didn't like it when people showed emotion around him so she tried not to do so, which was why she didn't go around him when she knew she was going to break down into tears. She usually went to Kanato when that happened, he oddly enough knew how to calm her down and he didn't mind her crying against him.

So when Shu pulled her into him she froze slightly, she didn't think he'd go to find her. She didn't want him to see her emotional side, especially when she was depressed. But she couldn't get out of the strong grip he had around her so she turned herself so she was facing his chest only to take in his scent and slowly start to break down. She couldn't keep it in anymore, she felt as if her body was finally just giving up on her.

"Why are you crying?" He asked as he looked down to her

She didn't say anything she just tried to push him off of the couch. He looked down at her as he saw her trying to get him off of the couch.

"Stop it, you aren't getting me off of here. Tell me why you're crying Selena." He said as he looked to her

"L-Leave me alone! J-Just...Go...Stay away from me if you don't want me to be near you!" She said sadly

He was then quiet as she spoke. "Do you really want me to leave?" He asked curiously to her

"JUST GO! LEAVE ME ALONE! Stop making me feel bad for being here already!" She said sadly as she continued to push him away from her

He held her hands within his own. "Selena, what has gotten into you this isn't like you at all."

"How the hell do you know what I'm like! I'm never myself around you!" She said as she cried " J-Just leave me be!"

He pulled her on top of him and closed his eyes for a moment before he sighed. Then he opened his eyes to move his face closer to hers before he kissed her. As his lips were against hers, he could taste whatever Reiji gave her which made him curious on what Reiji was doing with his cuddle buddy.

Selena couldn't believe that he was kissing her, she honestly thought that he was just using her. That she was just an object for his amusement nothing more, nothing less. She knew that he had tried many times to scare her off but it didn't work. She needed to find way to get him away from her, she didn't like that she was just being used like Yui was, she didn't deserve the tourer that he was placing her through. Not when it was obvious to her that he didn't like her in the same way that she had fallen for him.

So why was he trying to keep her from pushing him away from her? She didn't understand it, it was just so confusing her. What confused her even more was when he made her be back first on to the couch and he pinned her arms down as well. She moved her head to the side so she wouldn't have to see her face only to feel her hands be pinned above her head before he forced her to look at him.

"Will you stop be so stubborn this is so troublesome Selena." Shu said as he looked down to her

She still said nothing to him which made him frown slightly.

"Tell me something...do you love my brother Reiji."

Her body froze as she stared up at him before she shook her head no. Seeing that she shook her head it made him relieved for some reason to know that he hadn't lost her to his younger brother. Which then made him curious.

"Then tell me why when I passed his lab I smelled your scent." He said as he tightened the grasp on her wrists.

"He...He wanted me to try something. What it was I don't know but...it awoke a side to me I've been trying to conceal." She said sadly

"That'll explain your behavior..." He said as he let go of her wrists.

He closed his eyes for a moment only to feel her move from under him, he didn't want her to go. He wanted to sleep with her in his arms.

"I love you Selena." He said hoping she'd hear him

He heard the door open but not close. "No you don't...H-How can you say that when you just use me." She said sadly

He got up and he went straight behind her wrapping his arms around her as he placed his head into the top of hers. "I don't use you, I wouldn't ever do that."

Selena froze as she heard him speak. "H-How can I be sure you aren't just lying to me Shu?"

He placed his hands within hers as he held her hands lightly. "I wouldn't lie to you, its low and being dishonest is the worst...plus its too troublesome."

She giggled lightly before she looked up to him. "You think everything is troublesome Shu."

"Not everything.." He said with a small smile

She looked away from him blushing as she sighed "Are you sure about that?"

He turned her around and made her look up to him. "Yes, so am I going to hear it back or am I going to be stuck just being someone you occasionally sleep next to?"

Selena looked into his blue eyes for a moment before she closed her eyes and calmed her emotions that were going crazy within her before she looked up to him and she kissed him. "I love you Shu." She said softly against his lips

He kissed her back and pulled her closer before he placed a hand on her face. "I'm glad to here, now can we go back on the couch or are you just going to leave me?"

She gave him a small smile. "We can cuddle again."

He picked her up without another word before he lied both of them on the couch and wrapped his arms around her as he closed his eyes. He felt a lot better now that he had her beside him. It was one thing for him to just cuddle with her because she was there, it was another when he loved her and he couldn't do anything without thinking about the woman that had creped her way into his heart. He loved her and he wasn't going to let her go that easily, especially when he knew now that she had been holding back on him for so long.

As the two cuddled on the couch they fell asleep there as Shu made sure that his arms were protectively around his lover so no one could take her away from him as they slept, while Selena kept herself close to him as she face him. She enjoyed knowing that she was loved by him and that she wasn't being used. Her depression calmed down after she heard that he actually wanted to be with her. With his arms comfortably around her she was able to sleep better knowing that she was with her own cuddle bear.

Months went by since Shu had told Selena that he loved her, of course he still acted the same around her. Calling her cuddle bear when he wanted to feed from her, wrapping his arms around her and sleeping with her whenever he could. There were also times when he had her help him with school work since he slept through school all the time while she didn't. That all stopped suddenly when Selena realized that the full moon was around and she didn't see Shu anywhere inside.

So she checked outside only to see Shu with his arms around Yui. She didn't want to say anything about it so she didn't. She left and she went back inside to where she knew Kanato was, he was surprised to see her but enjoyed her company anyways.

"Why aren't you with your boyfriend? I thought that by now you two would be sleeping somewhere." Kanato asked after awhile of silence.

"He has Yui now.." She said sadly

Kanato looked to her confused. "Why do you say that? I thought you two were like glue with one another?"

"T-That's what I thought too...Then he starts to distant himself from me and I see tonight that its because he lost interest in me. He has my younger sister now...so I should be happy that he's happy...right?" Selena asked before she looked at him sadly

"Maybe, I really can't think that much right now miss selena."

"Right...because of the moon." She said before she moved closer to her and she moved her jacket away from her neck. "Go on...Usually I wouldn't allow you or the others to drink from me but I don't care anymore."

He placed his teddy down and he pulled her closer to him before he bit into her neck drinking from her. She sadly closed her eyes and calmed herself as she felt the blood leave her body. After he was done drinking from her he smiled at her.

"Thank you...Your sister isn't as nice as you are." Kanato said as he got his teddy from where he placed it

"You're welcome Kanato. All of you boys have that crazed blood lust thing so I guess I'm just going to have to deal with it." She said with a sigh

"Why don't you see Reiji about what you feel maybe he can help you out with it." Kanato suggested

She thought for a moment then nodded her head. "Alright I guess I can." She said before she kissed his cheek lightly. "Thank you for being a good friend Kanato."

She then left which made him smirk slightly as he saw his eldest brother from below. He knew that Selena didn't see Shu and that she didn't realize that Shu had watched him drink her blood. Kanato then jumped down and landed in front of Shu as he did so.

"Why were you drinking out of her Kanato." Shu said as he looked to the purple haired male.

"Why do you care you don't seem to want anything to do with her right?" Kanato said before he walked off. "Ask Reiji about it, maybe he'll give you a better answer."

After speaking with Kanato, Selena knocked on the lab door only to see Reiji unamused to see her. "What do you want?" He said coldly

"A bit of your time that's all." She said as she held on to the sleeves of her jacket tightly.

He was curious on why she'd want to be around him so he allowed her in before closing the door. She stayed standing up as Reiji sat down in the chair. "What did you want to speak about Selena, this is unlike you to come to me without me calling you here."

"I know, its because of recent events. I firmly believe that if I'm around you Shu will stay away from me." She said as she placed her hands in her pockets

"Why would you want him to be away from you, I thought you two we-" He said before she cut him off

"Shu found something in Yui. I saw them earlier and I'm not that dumb, I know what my eyes saw..." Selena said sadly

That was very surprising to Reiji, he didn't believe his elder brother had it in him to cheat. He thought that was more Laito's thing than Shu's, but he was wrong.

"Alright, you got my attention. What did you want out of me?"

"I know what the full moon does to all of you boys...I'm here so you can take blood out of me. I won't resist or anything like that. I-" She said before she was pushed into the wall and pinned.

"Selena you are one stupid girl, but I'll commend you for knowing your place unlike your sister." Reiji said before he moved her head to the side before he bit her.

She winced when she felt his fangs within her but said nothing, she once again calmed herself as she closed her eyes as she let her depression get the best of her. Once he was done drinking from her he placed her in the chair before he gave her a small cup of tea. She looked to him confused before she thanked him. As she drank the tea she felt herself become sleepy as she held the tea cup within her hands. Reiji knew that there was something wrong with what Selena said and went to find Shu about it. Which didn't take long since he found Shu within the hall.

"You smell like Selena, where is she?" Shu asked narrowing his eyes at his brother

"Asleep for the moment, what have you been doing with Yui that's making the girl you supposedly 'love' not only go to me but Kanato as well?" Reiji asked

Shu looked away as he shifted his weight a bit. "I thought I saw her.." He mumbled before he looked to his brother. "I am not with Yui, she was an idiot and fell out of a tree so I was helping her since I was there. Nothing more."

"It didn't look it from Selena's point of view, she believes that you are cheating on her with her own sister." Reiji said before he motioned to his lab. "She's sleeping in there right now, if you really want me to believe that you aren't cheating on her do something about her state of mind. I could feel her emotions when I drank from her. You seriously have no clue what you are doing yet you were the one who had the most affection out of the two of us."

Shu only blocked him out as he went past him, he took Selena out of the lab and into his room where he held her close to him, he couldn't believe that she thought that he did something so low as cheat on her. He wouldn't do that not when she was the only thing out there that could make his undead heart beat when it wasn't supposed to. He closed his eyes as he held her only to feel her move away from him and the lonely feeling return to him as he opened his eyes.

"don't you dare touch me! I can't believe you!" She said sadly

"Can you lower your voice Selena, I realize you think something happened between Yui and I but-" He said before she interrupted him

"I don't care, honestly I shouldn't have gotten so close to you." She said before she left his room slamming the door

She left more than slightly pissed off, Shu only sighed and lied on his back. He didn't understand her and he didn't think he would ever understand her.

Selena walked around the mansion only to be founded by both Laito and Ayato. Laito had found her as she was going down the steps. He had pushed her down and bit and drank out of her left thigh. Ayato had found her as she was walking around looking for Yui to speak with her, he pinned her to the wall of the house and drank out of her left wrist when she didn't answer a question he had asked her. When Selena finally found Yui, Yui was still by the tree that she had found out about her sister back stabbing her.

Selena went up to her and crossed her arms. Yui looked to her sadly. "Selena I'm s-"

"Shut up. Don't even start with your empty apology's I want to make one thing clear to you, you stupid moronic brat. Shu is MY vampire, I don't care if he is a kind male and he did something for you. You get near Shu one more time and I will find the sharpest object I can and I will personally kill you!" Selena said darkly as she looked down at Yui

Yui frowned as she looked up at Selena, she was afraid of her adopted sister, she didn't know how to tell Selena that there wasn't anything between the two of them.

"Sel-" Yui said sadly

"I don't want to hear it, Stay away from Shu. This is your only and final warning. I see you around him I will personally kill you." Selena said before she left

She then got herself something to eat before she went to take a bath.

As she was in the tub she felt someone on top of her as she had her eyes closed. She opened one of her eyes only to see that Shu was on top of her. She didn't move as she felt him kiss her neck which was new but she didn't protest, she knew that he was trying to make her happy.

"You couldn't wait?" She asked curiously

"Saying that I actually want to be without you to begin with." He said before he moved a hand behind her neck. "I love you cuddle bear."

"Tch I don't believe that but go for it...Its not like all of your brothers haven't drank out of me today anyways."

He placed his nails into her neck as he bit her neck harder than he usually would have. She hissed in pain as she felt his fangs in her she placed her hands on his chest only to feel that it was bare. She opened her eyes fully to see that he was on top of her naked which made her blush deep red as she felt him move closer to her.

"You are mine cuddle bear, don't you dare ever let any of the others ever get to you like that again. I'll let you off with a warning this time around, but you do something like you did tonight again and I swear I'll make your night so painful you won't be able to move for days." Shu said lowly to her before he bit her again that time moving himself into her as hard as he could making her scream out in pain as her virginity taken by him.

He groaned a bit before he moved in and out of her in a some-what fast pace making her first whimper in pain from him taking her virginity before she began to moan loudly, begging him to go harder and faster into her. Shu didn't waste any time making her scream his name as his movements got rougher within her. He was going to punish her for allowing his brothers to bite out of her. He disliked having her go to his brothers, he was going to show her just how much he wanted her beside her; just what she meant to him. After them both releasing shu took them out of the bathroom and to his room where he continued to pleasure Selena, not letting either one of them sleep that night.

After that night Shu went back to cuddling with her but he didn't sleep as much in class anymore due to hearing some of his classmates flirting with what was his. He wanted nothing more than to keep Selena with him but he didn't know if she'd want the same life he had lived since birth. So when it came to the point in time where they could cuddle, Shu held her close to him as he made her look up to him.

"Tell me Selena, would you do anything just to stay with me?"Shu asked curiously

Selena looked up to him fairly shocked but smiled at the male. "Of course Shu, I'd do anything just to stay with you."

"Even if it means leaving your old life behind?"

She nodded her head silently before she saw him close his eyes. He let go of her face before he made it so he was lying against her chest. He stayed there for a while before he silently made his way to her neck before he kissed it softly.

"Are you hungry again Shu?" She asked softly

"No...Not this time." He said before he brushed her bangs out of the way of her face before he kissed her. "I love you Selena, but I don't want you to die on me like everything else has. I want you to always be beside me, I want you to see life through the eyes that I do."

"But you can't change me can you?" She asked curiously

"No, it doesn't work like that. As many people believe it'll take more than a human drinking a vampire's blood to have that human become a vampire themselves. But I've asked Reiji about what he did for Yui before and he said that he's willing to do it again if I'm willing to take responsibility for whatever happens with you." He said as he brushed his thumb against her cheek softly.

"W-Will you?" She asked shyly

"Of course, I wouldn't do this for no reason Selena, I wish for nothing more than to be with you for all eternity."

She giggled and smiled a bit. "so you want a cuddle buddy for life then huh?" She asked

"No...I want a lover for life, who I can cuddle with and who I know I can trust won't do anything troublesome."

"Then you better not do troublesome shit either." Selena said as she looked up to him seriously

"I know...But, for now lets just cuddle."

"Alright Shu, if that's what you want."

He lied against her and the two of them fell asleep on her bed where he made sure that he kept her close to him. Weeks later in a cup of tea that Reiji had given Selena was an elixir that he had made up for Yui for when Cordelia had made her self known in the house yet again. When she drank the tea she felt like she was going to throw up but she finished the tea before she rushed out of Reiji's lab. She threw up in the bathroom before she brushed her teeth.

"Bleh that was gross." She muttered before she looked to the side of her to see that Shu was once again in the tub with his clothes on. "Again?"

"Undress me, its too troublesome for me to do so myself."

"Then I'll be taking a bath with you..Do you really want that?" She asked as she went up to him and moved her hands down his chest as she was behind him.

He hummed slightly before he opened his left eye. "Yes."

"Well that's unexpected, but alright." She said before she locked the bathroom door because of Yui. She then went into the water before undressing him and herself.

As moved closer to him she felt an urge within her she didn't know how to describe and she told Shu about it only to have him place a hand on the back of her head and force her to his neck. She realized what he meant by it and wrapped her arms around him before she bit him as he held her bare hips tightly. After their bath together Shu made sure that Selena was okay on her first week of a full moon only to see that she ended up biting her wrists instead of going to him.

"Are you really going to be that stupid." He said before he kissed her. "Don't make me have to punish you for hurting yourself, you promised me you wouldn't do that."

"Then stop being so damn hard to find!" She growled before she pinned him down she fed off of him.

After all three nights were over with he realized that Selena was acting a bit more differently than usual. She'd be around him more and bug him more to cuddle with him. Plus she showed her emotions a lot more which confused him before he realized that she was pregnant from the smell of her. It wasn't just the smell of her blood anymore, which messed with his head while he was around her. But he loved her all the same after she had their first child Katsu who had her brown eyes and his blond hair.

As promised Shu took the responsibility with Selena to raise their child throughout the time that they were together. Eventually Yui stopped messing with all of the other's heads and ended up with Ayato.

-End for Shu-
