I want a very shy girl who can fix anything [etc.]
Don't we all?
I'm going to have to go with a warrior-type person. Tall, slim, perfectly androgynous, long dark (almost metallic) blue hair that reaches to mid-back, slightly pale green eyes (i.e. not the dark green people throw around, something more subtle than that).
He (I'm going to call him "he" because it's easier) has an actual gender, but he enjoys breaking down people's perceptions of them, and occasionally dresses as full-on male or female to keep people wondering which he really is - although often he just stays to a neutral style. He's just as convincing either way around (hence the "perfectly androgynous"). He prefers to be referred to as "he"/"she" depending on his dressing mode at the time (either is fine for neutral).
Typical attire (the neutral look) is smart casual, but clothes that are equally easy to move in - he hates being restricted in any way (movement, philosophy, etc.). His outfits are usually based on one colour, using a few shades of one, and can wear green, blue, red and purple outfits (green being his favourite, as it complements his eyes - slightly pale, slightly washed out). He likes the flamboyant long coat thing, but only really wears it when he's not expecting to do any serious moving/fighting, as it would just get in his way.
He has a great sense of humour, but which is only really shown as him appreciating a good joke (his typical reaction is a smile - not a grin - more like admiration for the joke rather than a "lol" moment, and he very rarely actually laughs - a chuckle is only slightly less rare) and in making amusing comments (sometimes at inappropriate times, such as in a fight). He sees humour as more of an art form than a device to make people laugh, and appreciates and tells amusing comments rather like a critic would admire a painting (good or bad). He only infrequently says amusing things himself, but when he does he often gives a slight chuckle at it afterwards.
As fighting styles go, he can be known to dabble in some of the very many very different methods (which include whatever you like, but presumably will at the least be the Force, personal spiritual power, and magic, with possibly also metaforming (shapeshifting)). He mainly bases himself in personal spiritual power, though, and prefers not to get down and dirty with the fisticuffs. He has a number of defensive and offensive techniques (it's not all just ki blasts), including a couple of forms of Repel, arrow- and quarterstaff-based ki manipulations. He also has the
Felni Faus Bimin Tterhys (
fell-nih ff-OWW-ss bih-min terr-iss), a glaive staff that can form the user's ki into a blade (the more ki, the bigger the blade, but his is regular sized) - ki in general is nowhere near as all-destructive as Dragonball Z might claim, with most generic ki blasts being percussive only instead of destructive or explosive, whereas the Tterhys focuses it and turns it into a dangerous cutting entity.
He's rather keen on his appearance, and can spend some time fixing a bad hair day so his male/neutral/female guise for that day looks perfect. He owns a small range of beauty products, but is far from a make-up queen.
His life's philosophy is to do what you do, and do it as best and as hard as you can. And enjoy yourself, which means no stressing out over something. If trying too hard is making you feel bad, don't try so hard - being happy is more preferable than being perfect.
He may well be a little provocative/flirty with people, particularly new people, but this is very mainly only to prod people into questioning their opinions on gender (because while this world/galaxy is very liberal, it's very much a case of Not Everyone Is Bi, and gender-confusing people is fun to do, at least for this guy).
He blends in quite well with his friends, and although he may be a little quiet, he's far from the lone wolf/the strong silent distant type. He's very reasonable, rarely gets in any sort of mood/huff, and is immensely loyal to his friends (but y'know, don't put him in life-or-death scenarios every week to save someone just to prove it).
His name is
An Kalsetti Shoryui, or An or Yui (nickname/by comrades) for short. "An" is his familiar name, purely a cultural thing and it's never recorded in official records; it's also highly impolite to refer to someone by their familiar name if that person hasn't allowed you to do so (and the name you'll always use if you're allowed to - it signifies that deep a bond and using it honours that bond). His regular "first name" is Kalsetti, and Yui is a nickname that some people may use (but certainly not everyone). He's no relation to Kelfen Shoryui, famous ki user dating from a hundred years ago, as he will patiently explain.
Did you get all that?
