Fairy maid didn't work out so I decided to do something almost as dumb instead.  Whee.

[list][*][u][b]Name:[/b][/u] Ruukoto
[*][u][b]Appearance:[/b][/u] [url=https://safebooru.org/index.php?page=post&s=view&id=2433249]Multi-Purpose Android[/url]
[*][u][b]Ability/Skills:[/b][/u] Unlike the majority of Gensokyo's inhabitants, Ruukoto is not magical in any way.  She is in fact an android, a machine designed to look like a human, and her origin is purely scientific.  Her mechanical body possesses far greater strength and durability than humans and even most youkai, and she is equipped with an anti-gravity unit allowing her to fly.  Due to being a mechanical construct with a computer instead of a brain, a lot of abilities that affect either the bodies or minds of living beings are ineffective against her.  Despite being a maid, she is very bad at any kind of maidwork, yet her combat capabilities are far more competent.  She is equipped with multiple features that don't seem very useful for a maid, such as eye beams, fingertip-mounted laser blasters, rocket punches, hurricane breath, a chest blaster and a seemingly endless supply of missiles.  Why a [i]maid[/i] of all things would need these is a mystery for the ages.
[*][u][b]Personality:[/b][/u] Cheerful and overly-enthusiastic about her work as a maid, although her enthusiasm doesn't really make up for her lack of skill at household tasks.  She's always happy to serve, however, and will always do her best to help others (whether they like it or not).  She holds both Reimu and her former mistress in high regard, and whilst she's always unfailingly polite to others she might be a bit more curt with those who badmouth them.
[*][u][b]History:[/b][/u] A nuclear-powered robot maid gifted to Reimu Hakurei when she was young by a visitor from another world.  However, despite her enthusiasm she was never really any [i]good[/i] at maid work.  Her time at the Hakurei Shrine was also rather brief, as one day she went out to get milk for her mistress... Only to never return to the shrine.  Apparently, she got lost on her way to the store.  [i]For several years.[/i]  And even if she [i]does[/i] find her way back, Reimu has long since forgotten she even [i]had[/i] a maid to begin with, not to mention that the milk has long since gone off.  Still, she wants to get back to her job at the shrine as soon as possible.  Reimu is her mistress, after all, and what good is a maid without someone to serve?
[*][u][b]Other:[/b][/u] Due to how little information there is about the [i]canon[/i] Ruukoto, some liberties were taken.[/list]
