I would LOVE to help you get into rpg playing in the role of a female Mage. The system i would us would be a modified version of Mutants and Masterminds 2nd edition, but you need not own a copy of the rules, because I do. I haven't watched much anime, so it really wouldn't be based on that. At first, your character would have a definite list of low-powered spells, and guidance of a number of 'elemental pools' so that she could learn how magic works. Then she would learn some modifiers and start designing her own spells, and getting into spontaneous magik. Along the way she would be facing challenges. Should this be in a medieval world, or renaisance, or modern, or future, or what? I can do any. This group does not exist yet, and would probably start as a solo focused on you. Your variability of schedule can be explained with a phasing-curse (which would actually enable her to start with more points than 'normal'.)
