Author's Note: Yes, this is based somewhat off of Trick and Treat by Vocaloid, (Gakupo, Rin and Len :D), so… yeah. Anyway, this is my first Yullen (Kanda x Allen) story. I figured I might as well try the pairing sooner or later, and I thought… Why not do it in a creepy story? CX Anyway this is yaoi, so don't like, don't read. K'thx.

Italics are flashbacks, as always in my stories. :D

.:Preface:.

Allen thought of his doll; that doll he longed for. He wanted it and he couldn't resist the urge to get out of bed secretly to creep downstairs to the cabinet that held it. Opening up the cabinet was the hard part; Cross had a lock on it. Allen searched and searched, but couldn't find the key. He screamed out the name of the doll; it was enough to wake the drunken redheaded and he sent Allen off to bed again.

But Allen didn't give up. On his way up the stairs, he thought of a plan; a brilliant one at that. All he would have to do was dream of the doll opening the case for him.

He whispered as he walked up the stairs. "Please… Open the cabinet…!"

A few hours later into the night, Allen heard a ping and he stalked downstairs quietly. The cabinet was open. He ran to the case and picked up the doll. It was fairly sized, a rounded pale head with black little buttons for eyes. Wires made its mouth – a slight smirk was wiped across the doll's face, almost like it had a secret… A secret that Allen wanted to know.

He played with the doll's fine-strung hair; it was a dark blue, the color Allen had wanted. Ever since that one meeting, Allen was now free to admit his dreams he had been having. He told Cross to make him a doll; certain specifics to shape the doll into who was discovered in Allen's dreams as 'Yu Kanda'. Cross told him it wasn't a good habit to have a doll, especially one like the person he had been seeing, but Allen still fought against him and demanded for it.

He was supposed to be asleep by now; the luminous clock shone three AM, but he didn't care if he got in trouble with Cross. He wanted that doll to sleep by him. Every night.

Cross had locked up 'Yuu-san' – the name Allen had picked for the doll – because he feared Allen's Yuu-san would come back to haunt him somehow. Allen shrugged it off and went to bed, and now here he was, holding Yuu-san the way Yuu-san wanted him to carry him. Allen held him close to his ear and (pretended to) hear the doll say, "Dō itashimashite, Alley-kun," before carrying the doll to his bed.

Inside his room, Allen had a lamp that he set down on his desk; he turned to look at Yuu-san 'watching' him, or so it seemed. Allen was fearful of this doll's expression but how much he adored the doll itself balanced the fear and toned it down a bit. The lamp created shadows on Yuu-san's head and body, creating a deeper, creepier atmosphere around him. Allen raised an eyebrow and decided to hold the doll close to his body, taking shaky breaths. He sighed, getting into bed. And before he remembered to blow out the candle in the lamp, the little Moyashi was fast asleep with Yuu-san in his arms.

Allen heard Cross screaming for him to get up; he woke up with a start to see his entire desk and other areas on fire. He looked around for Yuu-san; the doll was not to be found. Allen looked and looked for it, but he couldn't find him.

He began crying instantly and Cross tried dragged him out of the burning house. Allen looked down and saw a black hand, one like Yuu-san's! Allen immediately grabbed it and let Cross drag him outside, clearly satisfied.

But when the house collapsed, due to its fragility and age (the wood was dry and was easy to burn), it was then Allen looked down and saw he grabbed a black teddy bear, not Yuu-san.

"Master Cross!" The little boy cried, but Cross just stared at the amber flames rising to the sky. Allen watched them too, and soon he was longing for the doll again.

He went into the scorned house, dodging wood, trying to locate where his room would've been to look for any trace of Yuu-san.

But he wasn't there… No remainders left, just burnt books, his bed, and his clothing.

Allen broke down and collapsed.

There, his thoughts went wild, and Cross had to drag him out of the fire twice now, because he wasn't coming to consciousness anytime soon.

Not when he was missing his Yuu-san.
