SailorStar9: Well, I was re-watching the Punk Hazard Arc of One Piece for the last two weeks or so and browsing through the Sailor Moon/One Piece crossover section when my plot bunnies gave birth to this fic in my dreams, no less.

Fic summary: During Punk Hazard Arc but before the Straw Hats arrive. "What are you doing here, Amy-ya?" Law muttered, following the navy-haired pharmacist through the lab. More than ten years earlier, before Flevance's destruction, young Law met young Amy by chance. Years later, he finds her on Punk Hazard, working under Caesar Clown.

Pairings: Trafalgar Law/Anderson Amy (Because, really, out of all the Sailor Moon/One Piece fics out there, how come no one ever thought of this pairing?)

Disclaimers: One Piece and Sailor Moon belong to Oda Eiichirō-sensei and Takeuchi Naoko-sensei respectively . Me, on the other hand, own absolutely nothing, except this pairing and plot, I hope.

Prologue: Beginnings

Close to 17 years before present...

"Darling," Law's mother entered the study. "Nikki-san's here."

"Ah," Law's father looked up and spotted the younger female doctor at the door. "Nikki, welcome."

"I apologize for the interruption, senpai." the divorcee bowed slightly. "Amy-chan, don't be shy." she nudged her daughter from behind her.

"Hello." the blue-haired girl peered from behind her mother's legs.

"Law," Law's father looked at his son hunched over the study table. "Can you take Amy to the hospital library? Tou-san has something important to discuss with Amy's mother."

"Okay." the nine-year-old Law nodded and slid off the chair.

"Nikki, are you sure about this?" Law's father's question became muffled when Anderson Nikki shut the door behind them.

"Follow me." Law instructed, taking the lead.

Once in the library, the two children separated to find the books they wanted.

"Medicine?" Law looked at the title of the rather thick medical text the girl had pulled out. "Are you sure you understand the contents?"

"Hm." Amy nodded. "I've already finished the earlier editions; I've been waiting for this edition to arrive at Notice."

"I see." Law mumbled and returned his attention to the surgical text he was poring over earlier.

Hours later...

"Amy-chan, it's time..." Nikki opened the library door to retrieve her daughter and smiled when she saw the two children dozing off against each other, Amy using Law's shoulder as a pillow.

"Aw, so cute." Law's mother gushed quietly. "Oh my," she looked at the completed chess game laid out on one of the wooden tables. "Amy-chan plays chess, Nikki-san?"

"Yes." Nikki nodded. "Amy-chan, wake up." she gently shook her daughter awake.

"Law, wake up." Law's mother rested a hand on her son's shoulder.

"Is it time, kaa-san?" Amy rubbed her eyes, stifling a yawn.

"What time is it, kaa-sama?" Law gave himself a stretch.

"The Andersons are leaving." Law's mother replied.

"Already?" Law echoed. "But I haven't..."

"Let's play again when we visit next time, okay?" Amy beamed, giving Law a peck on the cheek and let her mother lead her off.

"Okay..." Law muttered, blushing slightly, a hand on the cheek Amy had just kissed.

"Ara, your first crush, Law?" Law's mother teased.

"Kaa-sama!" Law spluttered, his blush deepening.
