Oh alright, I'm in! I just can't resist the idea of this Chris!!!!
FIGHT! FIGHT!
Here's Serena in the ring once again. 

Height: 6’
Weight: C’mon. You just can’t ask a girl that. Especially this one!
Back-story: In her youth Serena studied alchemy and conjuration. (Her parents were both Magically inclined.) She became a master at alchemy at a very early age. Her conjure skills, however, are barely above average. She became restless and bored by the time she was 12. She became obsessed with training her body as she had her mind. She set her sights on martial arts. She became a master.
Eventually, (a girls gotta eat ya know) she became hired muscle. A body guard for the rich and elite. It was boring, but paid well.
Through this line of work, she met a colleague who intrigued her with his mystery. His name was Yoshiedo. Eventually Serena and Yoshiedo became close friends. Well, as close as you could get in that line of business.
As Yoshiedo was fascinated by her skills in alchemy and conjuration, so was Serena fascinated by his history and skills of the Ninja. They agreed to exchange knowledge and training.
In addition to Serena’s Master Alchemy, Moderate Conjure and Master Martial Art skills, Serena became trained in the way of the Ninja. She has many tricks up her sleeve, literally. Some say she even learned the art of teleportation. But none know for sure. Serena is also very skilled in advanced cyber and computer technology. (Another gift from Yoshiedo).
Many gossip how strange it is that she never carries a sword. The truth of the matter revolves around tragedy in her past. She refuses to speak of it. Whatever it was, she vowed never to wield the Katana again. And she now seems to have a never ending appetite for fighting.
Serena wears a flexible, light, but strong body armor. Her sleeves and boots are made from the same high tech material. The collar remains rigid...all the better for an opponent to stab themselves if they get too close. Hey, a girl needs her space yo! But if you do get in close? Might I suggest forgoing that kiss? Rumor has it, it’s no good for your health.
Her visible weapons are her Sais, and throwing stars. She carries a few “supplies” in her pouches attached to her belt.
