Charming Little Sister - (Diabolik Lovers x Reader)

Chapter 6: Shu Tastes Blood!

"Come in." Reiji said coldly. You slowly turn the knob of the door, and quickly closed it with a slight slam. Reiji was baffled by your behavior, but at the same time, he felt amazed by it.

He turned his head from the paper on his desk to you, as he pulled his chair for his body to fully face your direction. "What is it that is so important to you that you must disturb my work?"

"...I apologized to you. Now you apologize to me. And our brothers! And that girl!" You said as you put on a brave face. Suddenly, Reiji was in front of you, inches away from your face.

He took your fingers to push his glasses up on the bridge of his nose. You were nervous, you certainly thought he'd bite off your fingers, or break your hand entirely.

"Why should I? You were being a brat. A child like you needs discipline. But that's the thing, you are a child. It really does you no good to misbehave like that, especially at the table. Ayato always manages to make you misbehave one way or another." Reiji chuckled at your fear. You still openly listened, completely silent.

"Oh, and have you noticed Ayato's strange behavior? Be honest with me, (Y/N)."

You gulped. "N-No..."

"Oh? You haven't? He's always spending time with that----"

"AHH!" You both heard Yui's scream fill the room. What's wrong with her?

"Damn these walls and ceilings being hollow..." Reiji growled as he pulled away from you and back to his work.

You quietly backed away and turned your body to walk towards the door. You heard Reiji chuckling behind you.

"(Y/N), know that I don't just hurt you to make sure you be a good girl." You froze in your place. "I also hurt you because I just love how your face contorts into fear and misery. You're just that much cuter like that, don't you think?"

That was enough. You exited the room quickly and closed the door behind you. However, you were greeted by a strange surprise. Laito and Kanato were missing. You wondered how, and why they'd leave, but you were interrupted by a familiar scent. You sniffed the air, and welcomed the sweet aroma into your lungs.

You followed it upstairs and stopped as it got stronger in front of a door. Yui's room. It had to be. You turned the knob slowly and opened the door to a crack. The scent was strong, but no one was in the room. You decided to follow it once more and was met by the explosion of many shades of pink in the bedroom, tanned pink sheets caressing the bed posts, a darker pink bed, and light pink carpet. 'Whoever decorated this room went really overboard with the pink...'

You traced the scent to another door lined against another wall. You knew it had to be bathroom, because each of your brothers have a master bathroom. Except you. You got the smallest room in the home. You enjoyed it, since you thought it was really cozy and it gets warm easily.

There was a small crack in the bathroom door, and you peeked through it, opening the door slightly to enhance your field of vision. You saw a strange sight. There was Yui in the tub---- with her clothes still on---- with Shu! But that wasn't the strangest part, Shu had his mouth on Yui's shoulder. Little beads of crimson formed from her rather pale skin and fell into the bath water, dissolving quickly into it. The smell of the crimson droplets became even stronger. But your interest was cut short when you noticed Shu pull away from Yui's bloody shoulder. You saw that she had a wound in the form of two red puncture marks. Shu had a very similar appearance to Ayato, as he also had bloodied fangs, with droplets of blood oozing down his lips. You caught him nearing his sights toward you, and you quickly backed away out of his field of vision. You rested yourself against the nearby wall seperating the bathroom and the bedroom.

You sighed out relief but quickly sucked the air back in when you had a very worried Yui sitting in front of you, covering her wound with her palm.

"(Y-Y/N)? What are you doing here...?" Yui asked nervously.

You couldn't tell her the full truth. But you decided to come half-clean, because you could never fully lie. Your brothers could always figure you out. They know you perfectly well, your actions, your thoughts, all too well. "W-Well... I heard you scream... So I wanted to come see... But all I saw was an empty room. So I waited for you..."

"O-Oh? That was all? You're so sweet..." Yui sighed, obviously relieved at your answer.

You two carried on a normal conversation, despite the uncomfortable atmosphere earlier. All until...

"HEY! YUI! WHO'S THE BASTARD THAT BIT YOU--- (Y/N)?" Ayato barged in, but taken by surprise as he saw you in here. "What are you doing here?"

"I heard Yui scream. So I came in here to check on her!" You desperately tried convincing him.

Ayato eyed you suspiciously. Then he suddenly grabbed your wrist and jerked you out the room. He noticed Yui covering her wound. He smelled it. Her blood. He knew that someone bit into her, his prey. He knew who it was, he sensed the malicious aura. But he had to worry about you, his little sister.

He didn't want you to know that Shu tasted blood.
