Gilded Guardian Gilda
We have two national efforts, lets get some more effort to national with!
Gilda's brother always dreamed of joining the academy, learning magic, and exploding Moskurgers, and she always supported these noble dreams. Trajically, while ploughing the frozen fields together, her brother suddenly died of exposure the day before he could apply. Yearning to see her brother's dreams fulfilled, young Gilda donned a disguise and entered the academy in guise of her beloved brother, hoping to bring glory to his name. At the acedmy she spent 2-4 seasons engaged in various hilarious and dramatic hijinks.
She gained the favour of an enigmatic mystic talking owl. Found it to be entirely far too enigmatic so she broke its legs and tied it to a stick. It was much less enigmatic after that and behaved really well so she rebroke its legs and splinted them properly and it has since learned to crudely hobble around under its own power...
She met an annoying boy, had a long string of arguments and abusive exchanges, fell in love as destiny decreed, saw him mind controlled in a Mosskurger scheme, promptly ripped his head off with her bare hands set his corpse on fire, threw it from a precipitous cliff, and then jumped after it, landing atop the remains and sending the charred gore across the landscape. You can never be too careful with Mosskurgers...
Of course she had an endless series of near-misses with her disguise. Constantly using the wrong chamber pot. Suffering assorted side-effects from hair-growth spells she used to fake stubble while on field expeditions. Causing consternation amongst new arrivals who found his/her figure strangely alluring... OF course, this all ended in the series finale when she used her ultimate magic before the whole assembly to save the academy from a Giant all-knowing betentacled Mosskurger mind-parasite...
Speaking of her ultimate magic, she spontaneously developed a unique form of crystal manipulation. This takes the form of various physical rituals that look almost like dancing, accompanied by various crystal formations forming and shattering that sound almost like some sort of personal backing music, and then there is the strangely unnoticed crystallisation of the surrounding time which causes the rest of existence to fragmentally stop for the 15-50 seconds it takes for her to perform any given ritual that makes it seem for all the world as though everyone just stands around and lets her do it...
The effects of these rituals is to cover her in various crystal formations that vary starting with a thin covering over her skin(and forming a miniskirt for some reason) which offers protection and empowerment as she can magically compel the crystal to move with more force than her muscles alone. The most advanced form includes a summoned winged horse, wings of her own, a large ornate headdress, numerous gem-like formations, and all manner of other additions leading her to appear just like a grand valkyrie of legends hurling crystal spears around the battlefield. All of her crystals have a unique golden tint to them and produce a subtle glow.
But generally she just sits on a building making things cold, or waves a fire-stick around...
And no, I don't feel guilty about proposing a magical girl.
