Rain crashed down, eager to meet the ground below. The winds were unforgiving, cutting like glass. Animals and humans took shelter from the harsh weather. Thunder boomed; lightning cracked the sky filled with dark clouds. The sun was nowhere in sight.

In a forest, miles away from civilization, a small cottage stood. Light could be seen coming from the windows which had rain droplets streaming down them. Inside, a woman was sitting on a chair, rocking back and forth gently. In her arms, she held her newborn daughter. The woman looked down at her with the softest expression, her eyes shining with undeniable love. The baby cooed softly, happily. Unbothered by the storm, the two were living in their own little world.

Suddenly, the woman tensed and holds her child closer. "What are you doing here?" Her voice held icy impassiveness. She lifted her gaze towards the man who stood across the room from her.

Their eyes met and the man smiled. The smile seemed friendly and harmless, but the woman knew better. "A little birdie told me that you were blessed with a child. I wanted to give my congratulations. I even brought a gift for the bundle of joy." With his smile still in place, the man took a step closer and held up a stuffed animal. It was a pink bunny.

The woman gave him a withering glare. "Don't come any closer. My child will not have anything of yours. You aren't welcomed here. Leave." She hissed.

He chuckled. "Now, there's no need to be so hostile. I wish no harm to you or your daughter. I just want to discuss the deal we made."

Dread filled the woman, "No, no." She refused. "You can't have her."

"A deal's a deal, Morika." He was still smiling. "I've up held my end of the bargain. You can't back out now." His eyes began to glow, malevolence clear as day. "If you try to, you know I'll be very displeased."

The woman showed no fear and held his gaze. "You can't intimidate me, Karlheinz. You know what I'm capable of. You may be King, but you have no power over me." Her eyes glowed as well, showing an indisputable strength.

Karlheinz's eyes narrowed, his gentle façade was gone. "It doesn't matter how strong you are, Morika. The deal can't be broken. You know this. You can't stop the inevitable." His persona began to make an appearance again. "I'll leave you be for now. But once she turns sixteen, she'll have to meet them." The smile was back as if it never left. "I do enjoy out chats despite their rather unpleasant topics. Take care, Morika." As soon as he said his farewell, he disappeared. A stuffed bunny laid where he once stood.

Morika was alone with her baby once again. But the contentment from before was gone. In its place was a strong sense of unease and apprehension. As if sensing it, the child began to fuss and let out a cry.

The mother began to rock again and gently shushed her. "Shhh. It's okay. We'll be okay." The cries stopped, but the baby was still unhappy. Morika softly hummed a sweet lullaby, causing the child to slowly drift to sleep.

The storm continued to rage outside. But Morika paid no attention to it. She was focused on her sleeping daughter.

"I won't let anyone hurt you. Especially, not him or his sons. Mama will protect you. I swear by the Heavens above that I'll keep you safe, my sweet Yui."

A/N: This is my first attempt at a Diabolik Lovers fanfic. I hope you like it so far. Just to let you guys know, I'm not planning on including Cordelia's heart plot in this story. Also, Yui is still going to be the kindhearted person she is, but she'll be a bit more feisty. Sorry for any grammatical errors. Comments are always welcomed.
