A\N: I know I said I won't make any more changes, but reviewing it seems a hard to follow. Their only three changes I made to Lightning, she has a wolf tail, her age is 17 and added a middle name, Vergil.
Lightning's theme: Who I Am from Magna-Fi
Prologue: The Broken Blue Knight
A large thunderclap erupted throughout the Emerald Forest. Lightning used her powerful Thundaga spell, to kill a group of Beowolves. Seeing their fallen comrades enraged them, and lunge towards the girl in a long hooded black jacket with a white star on the back. She's easily dodged their relentless onslaughts. Noticing that, they're grouped up together. Lightning unleashed her signature Ruinga spell. The light gray orb launched from her dark blue fingerless glove and flew towards her targets. It exploded on impact, with enough force of a large frag grenade.
Once where Beowolves are now a pile of limbs. Hearing snarls and growls behind her, Lightning quickly moved her hand back to the gunblade case. Within a blink of an eye, she draws her blade and cleaved the wolves in two. More Beowolves rushed towards the hooded girl. With a flick of the wrist, she transforms gunblade into gun mode, and with pinpoint accuracy, shot off their heads and limbs. Only about five remain and one large alpha. Getting tired of this, she decided to end this battle. She lifted the hand guard and popped out a magazine. Replacing it with one marked with her personal emblem. Lightning activated her aura, her body glowed a dark shade of blue. Lightning teleported to each wolf, cut them down one by one.
Leaving only the Alpha Beowolf standing. She used her aura to levitate and did a midair front her gunblade behind her, Lightning pulled the trigger. Lunging forward like a rocket and did a mighty vertical slash. But she wasn't done yet. Lightning turned in midair and pointed her gunblade behind her again, and fired another shot. The alpha Beowolf was helpless against the relentless assault from all sides. All the beast can see was blue streaks of light and blue rose petals. She stops in front of it and performed an upward slash that drags both her and the Grimm high in the air, called High Time. Lightning then follows up with a downward strike named Helm Breaker. As soon as they touched the ground. A giant pillar of light erupted beneath the Grimm and devolved in the light.
Lightning stood up but fell on her knee, "I guess... I'm strong enough to use the Army Of One... At its full strength, yet." she panted heavily. The Army Of One is a powerful attack that requires great skill with a gunblade and, complete mastery of their aura. The attack has three forms. Its simple form is a flurry of fast hard hit strikes for the gunblade and, heavy kicks. No usage of aura required. The second form is called Legion of One. It is the same as the first form, but it requires aura, and it ends launching the opponent into the air. Jumping over it, and dragging back down, creating a giant pillar of light upon landing. The final form is the true form of the Army Of One. Called Shin Army Of One. The user must use their aura to make their body light as a feather. So one can unleash an onslaught of slashes from all sides. Lightning has mastered the first and second form of Army Of One. But has yet to master the final form.
Lightning has great skill with her gunblade. She was able to learn how to use a gunblade. Thanks to her father and mother's earlier teachings and the secret volumes on using a gunblade. But her aura is where she has the most trouble. The reason is half of her aura has been locked away. It's because there is a part of her aura that must be hidden, as the other half is demonic. If the Schnee Dust Company or the White Fang finds out. Things will much harder, more difficult for her. Then it already is. By only able to use half of her aura. Lightning can only use it as armor or, to use Legion of One.
She entered and won a tournament last year. She was called the greatest gunblade welder of this generation. It was easy for her because her opponents keep underestimating Lightning cause of her age and the fact she a Faunus. But there was one who gave her first real challenge.
The winner of the tournament three times in a row, Pyrrha Nikos. She remembered that the fight was extremely close, and she won by the skin of her teeth. Pyrrha's shield was able to block her both High Time, and Helm Breaker attacks. She can also throw that shield with great aim, and manage to toss it. Right at Lightning's abdomen, all most knock the wind out of her. Returning the favor, Lightning used a powerful thrust attack, called Stinger. It hit Pyrrha hard and sent her flying a few feet. Both Lightning and Pyrrha was down to their last shred of aura. Betting it all. Lightning used her speed to get close and unleash Legion of One. Thankfully, it was enough to win her the duel. Pyrrha was a good sport about her loss and congratulated her on her victory.
After regaining her strength, she got up and when to her cabin deep in the forest. It was average size, the walls and roof match the trees surrounding it. So it can blend in with the forest. Making it hard to find. It's also where there is no Grimm around. So it was the perfect place for Lightning to rest. Only a Farron can find this cabin. Because it was the Farron family that built the cabin as a hidden training facility.
Finally arriving Lightning entered in her little hideout. Inside has everything for everyday needs, a bedroom, a kitchen, a study, a bathroom and a weapon rack. The study has generations of knowledge from Farrons of the past. Lightning used this information to further advance her skills. She mostly uses the weapon rack to hold her gunblade Overture and her black jacket.
If her battle gear has been damaged. She knows a human tailor named Oerba Dia Vanille. Who was a two years younger than Lightning. That will fix it for free. Lightning was grateful for Vanille and asked why. Vanille says she just wants to and was honored to work on a Farron battle gear. Lightning notice that Vanille's face always goes red when she asks that. It took Lightning a bit to catch on and, just smiled at that fact that someone has a crush on her. But it looks like she has competition for Vanille. With a 17-year-old, childhood friend and fellow Wolf Faunus named Oerba Yun Fang. Not that she cared. Lightning didn't time for romance. Only for battle, for vengeance, and to restore the Farron family honor. Lightning asked Fang about the White Fang, and she replied in a "well-mannered way" that they are a bunch of crooks and they give the rest of the Faunus a bad name. Which is why Lightning doesn't suspect every Faunus, for being in the White Fang even though she's one herself. Unlike that pitiful Schnee Family.
Lightning was living in the Emerald Forest alone for seven years. Her home wasn't always the Emerald Forest. It was Bodhum a seaside town, the birthplace of gunblades. The town was famous for its annual fireworks, and its resort-like atmosphere. But now it's no more. Now it's a town destroyed by war, a war between the White Fang and the Schnee Dust Company. It was because of both of them her home was destroyed, her family gone, and the most important person in her life stolen from her. She can still remember that horrible day, the fire, the screams, the gunfire, the blood. All as if it was like yesterday. Lightning's heart burns with rage every time she thought of that day seven years ago, "I'll make them pay for this." her voice sounding bitter and cold. She choice the Emerald Forest to live and train not to become a huntress. No, that dream died years ago, it was for revenge. Revenge for what the White Fang and the Schnee Dust Company did to her.
