I convert the school influence I get from working at the security job to Initiative rep, so I don't have to sacrifice work periods or training to do Initiative missions.
But I try to play "hero", or as if the Initiative was really checking what you do, so I don't put the girls in mind-control induced slavery and don't use non-subtle mindcraft (except for bisexualising whatshername sometimes). So, I have to earn my money the hard way. I don't even beg money from the girls, what kind of superhero does that?
Working school security with 3 pay augmentations earns between 180 and 230 quids a day, so I pull 900-1150 a week. Not too shabby.
I do the whole school year without combat powers, as I said, I prioritize social powers. Besides, beeing KOed by a bum's kick when you have Armor of Terra is just silly, so I keep my Billy a delicate flower until it's go-time.
