I'm thinking Magi Gil (placeholder name with a joke built in :p) went to college and got a practical degree like accounting not inpractical degree like art, but life has thrown her a curve ball and the only job she can get is at a grocery store that pays so shitty is still living with her parents. Maybe suffers from PTSD.

Also like in SGVY can a dude be turned into a girl to become a Magical Girl?
