Alright, I think I've got a fairly good grasp on my character;
As a little kid, he was trapped in a burning building caused by a monster fight. He thought he was going to die, until he was saved by a Guardian Magical Girl duo. After that, he devoted his entire life to training so that he could save lives like the people who saved him. He even studied biology, in hopes that when he found a Magical Girl to be his partner, he could find a way to augment his body with her magic (for example; if he partnered with a Magical Girl that used lightning magic, he could do something like Lighting Release Chakra Mode from Naruto). However as a result of this, his social development was pretty much stifled (ie; he Sacrificed Social Skills For Awesome Training), so he's socially awkward.
I'd like it if I could find a partner for him, since the Tank/DPS relationship in an RP excites me (odd, since I main Healer in WoW).
