I've addressed a lot of those issues while making the adjustments, most of what you hinted has already been fixed (I think).

a combat school (where he would be required to forge his own weapon) <- That's only required at [url=https://youtu.be/sLv6FfHlxmI?t=5m14s]Signal[/url] specifically, unless you show me evidence that says otherwise =D

it still takes some time to draw, aim, and fire <- Hence why it's drawn with a motor. I'm reasonably certain she can fire it faster than a bowman, at the very least the bursts of 5. And while the ammo may not be as compact as far as thickness goes, it is significantly shorter and thus much easier to carry and manipulate. Sure, it's no Coco's suitcase GAU-8, but I can make it work, and if I can't well, that's my [character's] problem, ain' it?

Anyhow, here's the updated thing. If the weapon were to be such a neck ache I'll see how I can rework it, but I'd like to avoid that if possible.

Skin color: Light tan
Face:
[indent]Heart shaped - pointed chin, wide hairline. Dominated by her large eyes, her nose is rather flat. The ears out of view most of the time.[/indent]Hair:
[indent]Waist length black mane, usually kept straight and flowing down her back. In combat she keeps it tied in a high ponytail.[/indent]Physique:
[indent]Opal is a lanky pole. She is fit, but not as much as to compromise her slender figure as she relies on stealth, keeping an eye on her weight.[/indent]Combat Outfit:
[indent]The archetypal ninja garb - not too loose to catch on stuff, not too tight to restrict movement. Reinforced with hard leather in places that could come to harm, but still very light. She wears a scarf covering her lower face.[/indent]Casual Outfit:
[indent]Black dresses, her favorite is a plain, sleeveless one. She never leaves all of her weapons behind, so one might find her knife strapped to her thigh. She is not fond of jewelry or makeup, only taking them on when the event she’s attending demands it.[/indent]
3) Characteristics:

Background:
[indent]Opal is the only daughter of an older couple, a renowned martial artist and a professional athlete. Her family has a long tradition of martial artists from her mother’s and athletes from her father’s sides respectively. She grew up on the outskirts of Vale in a smaller flat made in a reconstructed attic above the family’s gym.

Being human, her childhood was fairly normal save for the high expectations put to her. Choosing to follow both of her parents, she took up archery, combining both fighting and sport. Over the time though, she started leaning towards the martial arts, preferring such lifestyle over the publicity of an athlete. Her mother started teaching her to the full extent, including the morals and life organization that went along with it.

Her training bore fruit when she was accepted into combat school, growing the dream of using her skills as a huntress. She was rather disappointed during the first year, as she quickly found out there are always people - and not exactly just a few - that were better than her at what they did. She started training at fanatical levels, frustrated with being average rather than perfect.

She discovered her semblance one time when she finally overestimated her abilities, causing her to misjudge a jump and fall off of a four story building. She was able to fling herself in the direction of the nearest wall, making a hasty grab for a railing on one of the balconies.

She quickly discovered that her semblance only enhanced her physique, having a basis in her normal physical conditioning. With it however she was able to finally reach close to being top of her class by the time she graduated and set her eyes on Beacon to continue her training and provide new challenges.[/indent]
Personality:[indent]
Always under pressure, whether external or self imposed, Opal’s drive is to be the best in her craft to uphold her family legacy. Her upbringing has also made her rather polite, and always having a teacher figure in her life caused her to be quite submissive.

Opal’s self discipline is a defining part of her character, as she is able to do quite anything she sets her mind to, and if she isn’t, she works on improving until she can. It shows in most parts of her being, from her body language in always assuming quite a rigid, tense stance to her display of emotions, making her seem aloof and stone faced despite not being a cold hearted person.

Preoccupied with her training and studies she never made too many friends, preferring the company of a selected few she grown to trust implicitly. As such it is hard for her to initiate contacts, but she will not shy away when talked to.

Through her training she is rather liberal and has strong moral compass, not having a problem with the faunus or any other ethnic or social group as long as they abide by law and at least basic ethics. That said, she isn’t all nice, at times being quite self centered and she does not offer second chances too often.

4) Weapon

Name: [url=http://p3d.in/CwYOs]Blitzkrieg[/url] (3D - data heavy-ish)
Maker/Smith: Unknown/heritage
Type: Variable Ammo Portable Ballista
Weapon Derivation: Crossbow
Holstered/Sheathed Appearance:
[indent]The weapon comes with a folding stock, but is still large enough to use a shoulder strap. Opal carries a separate holster for the knife.[/indent]Form 1:
[indent]Unfolded the weapon is about 0.87 m long (bayonet included). The weapon is a miniaturized ballista reloaded from a magazine. Similar to a crossbow in function, it actually lacks the prod. Instead it has two separate, solid arms mounted on torsion springs to provide the force to eject the projectile. The front is fitted with a laser sight, flashlight and a bayonet for close range. The weapon is fitted with a scope that allows for precision firing up to 500 meters away and hitting the target reliably up to 750. It is capable of taking gravity loaded cartridges with 5 bolts each. The torsion springs are primed using an electric motor, taking power from the two dust batteries that also power the rest of the electronics. The folding stock can hold four pieces of ready ammunition.[/indent]Features/Capabilities:
[indent]The weapon takes multiple kinds of ammunition. The regular bolts are composed of two pieces, the body and the tip. Opal can use either capsule tips for impact fuse dust rounds or poison, and metal tips for piercing effect. The main body can also hold a dust ampule for delayed fuse rounds. To fit the cartridges and barrel, the bolts are made with discarding sabot. Furthermore, Opal has special types of ammo, such as grappling hook, signal flare or a short range cylindrical canister.[/indent]Planned/Possible Upgrades:[list]
[*]Converting into a gauss gun
[*]Acquiring a targeting computer, possibly a heads up display
[*]Side operated breech and spring loading
[*]Bipod
[*]Lightweight materials[/list]Notes:[list]
[*]Opal was given the weapon by her mother, a retired huntress herself.[/list]
5) Semblance:

Name: Stability
Type:Physical
General description: Allows the user to perform inhumane moves.
General limitations: Only works on the user.
Visual effect:[indent]When the semblance is activated, Opal’s irises seem to refract light.[/indent]Active ability:
[indent]The semblance increases the user’s stamina, strength and agility to about 150% of their normal abilities. It also grants them to shift and apply force to their center of mass, making otherwise unheard of maneuvers possible, such as airsteping or always landing on her feet. Opal also uses it to ease handling her weapon, improving her aim and reaction time.[/indent]
6) Combat info:

Position/Class: Scout/Support
Landing strategy:
[indent]Launching a grappling hook into the cliff to break her flight, rappelling down, using her semblance to dampen the forces at work.[/indent]Fighting style:
[indent]Opal prefers engaging at range from cover, well outside of any retaliation. Failing that, she specializes in a close support role, being more useful in supporting others at her side than fighting solo. If forced into a solo fight, she makes use of her martial arts training and semblance to do away with her opponents, relying on agile dodging and parries to prevent injuries. Opal is familiar with many weapons, simply having a preference for the ranged one.[/indent]
7) Trivia:[list]
[*]She doesn’t make many friends, preferring a small group of those who truly deserve it.
[*]Opal has a case of arachnophobia.
