DxD: Mechanic's Scrapyard

A street rat with an uncanny affinity for machines reincarnates into a world he, now she, has no knowledge of. Being a child again in the wrong gender at that was a bit weird, but that was nothing compared to finding out what sort of beings she was now living amongst. She shrugged her shoulders "Well as long as they don't mess with my scrapyard." --- Author Note: Just a disclaimer for those who don't like OP MC's, she will be pretty OP and I don't really like situations where stories forces the MC to go against someone they literally have no chance of winning against. For those curious about Romance? I don't know, pretty much nothing is planned, however if I do decide to try, the love interest will also be female. The Cover picture is Jona from Alchemy Stars.
