In the fusion world of Moon Piece, Haruka is the cyborg shipwright from Water 7 who comes to join the Moonlight Pirates. She was born in South Blue as the only child of a well-to-do merchant and came to Water 7 at an early age with her parents when they'd decided to settle there. Little Haruka was a problem child, however, always running wild on streets and canals, getting into bull races and street fights, talking about becoming a mechanic or a carpenter of some sorts; and when her parents left Water 7 for a nearby island they didn't bring her along. They just left her a bank account to do the best she could at the age of 13. There were various ups-and-downs after that where Haruka ran in with bad crowds, got a rudimentary gang of sorts, then did a relly stupid dare which nearly got her killed through a scrape with the Puffing Tom on one of its earliest journeys. Haruka woke up with new metal body part: both her arms, most of her torso, plus some more reconstructed parts like her throat. An extremely good shipwright had saved her this way. (Might even have been Iceburg, but I'm none too sure of this.) Whoever it was, Haruka now felt indebted to that shipwright and did unpaid chores for him (or her?? Don't know!) until she succeeded into becoming an apprentice there. By now she'd figured out what her dream was - to build the fastest ship in the whole world and then go around the world in it - but she was determined to stay and help out her benefactor with the business, not just learn for her own sake. (So maybe it wasn't Iceburg but someone with a smaller company, needing more help.) But while she worked hard, she still got into street fights quite often as her old reputation hanged around. She also felt somewhat responsible for the proto-gang she had assembled, a small group of motley people who didn't have anyone else to turn to. (Haruka's leader style was way more aloof than Franky's, though, and not just because she tried to keep a low profile.) Haruka has modified some of her new body parts herself into useful weapons à la Franky, but in a less goofy and less extensive way. She'd hate to look uncool, after all! When she was fifteen, shortly before her accident, she met a beautiful girl her own age who played an enchanting melody on the violin. They got to talking, even sharing their dreams with each other. Haruka hoped to meet that lady again one day: the memory inspired her to keep aiming higher, even if she still prioritised helping the "old man" who saved her life. Until she met the Moonlight Pirates and her life changed!
