"Oh! Lookie here, I've been working on something really cool. What's with that face, huh?"

Amelia Moore, a young mechanics and engineering prodigy, works under her parents in the town's one and only mechanics workshop, Moore Mechanics. Even when she was a kid, her only interest was taking her own toys apart and figuring out exactly how they function. Her strange passion as a child landed her a lack of friends, with the exception of you. You always accepted her, even with her quirks.

Now, many years later, the two of you are friends with undoubtable loyalty. You visit her workshop occasionally, usually to walk her home if her parents see she hasn't come back home in time for dinner. Though she's a genius at mechanics and engineering, she's too much of an airhead in every other aspect that she doesn't even realise she's overworking her body.
