Prompt: Hollow
Pairing: Izaya OriharaxOC

"Izaya-kuuuuun!" She ran halfway across the park after catching a mere glimpse of the information broker. He could not help being amused by her lack of coordination as she tripped over her feet in an effort to reach him, landing on the ground with a soft thud. A few people in Ikebukuro park turned to look at her questioningly, mostly likely wondering what she had taken to give her that much energy.

He had known her long enough to answer that question; she was the kind of girl that did not need artificial methods to be lively. He sometimes wondered why such a pure, innocent girl was attracted to him. A smirk spread across his face as he considered tainting that purity, just to see what would happen. What if he were to lure her into his dark world with a promise of his companionship, then abandon her at the very last moment? It would be thrilling to see her face at the end; after all, humans were so very interesting.

"Oh, hello, Yumi-chan." He gave her a fake but convincing smile while she rose to her feet. "Nice to see you," he said, even though he was not pleased with seeing her individually. His statement was directed more toward humanity in general.

She did not seem to notice. "It's great to see you too, Izaya-kun. It's been awhile, hasn't it? How have you been?"

"Wonderful," he answered truthfully. Everything was getting so interesting, especially since he had obtained the Dullahan's head.

"Of course. You're always wonderful, aren't you? I'm pretty good myself. My life's been a bit crazy, though. That black rider and all...," she muttered.

He chuckled softly. "Life in the city." She answered him with a stubborn glare, something that, to him, proved her innocence all the more. Innocence slowly corrupted by the dark side of the city she loved...

"Easy for you to say, Izaya-kun." She giggled in spite of her annoyance, momentarily grabbing his full attention. He only half-listened to her rattling as they walked through the park, his mind again wandering toward his priorities. About ten minutes later, though, he was brought back to reality.

Her arms wrapped around his waist as soon as she heard the roll of thunder. He was caught a bit off-guard by the sudden gesture. "Izaya-kun, can we find a place to hide?" she whimpered.

Such a child, he thought. Such a pure, pure child. "Sure, Yumi-chan."

"There!" She grabbed his arm and dragged him toward an unlikely shelter: the hollow of a tree. He questioned two things as they crawled into the roomy hollow: her decision-making and his judgment. Why would he, of all people, agree to wedge himself in the hollow with her?

She buried her face in his jacket each time she heard the thunder. He sat there, still wondering how he let himself get dragged into the tree, not paying much attention to the shivering girl beside him. At least, that's how it was at first.

Her thin arms again wrapped around his waist, but her body gradually stopped shaking. When her breathing slowed, he knew she had fallen asleep. He made no move to wake her; he sat there and watched the rain.

The information broker chuckled when she whispered his name in her sleep. "Silly, silly girl." He glanced at her before turning his attention elsewhere. However, no matter what he thought of, the genuine smile never vanished from his face. He would later wonder exactly how his plans had been interrupted by something as simple as rain and the hollow of a tree.
