I like the premise. It reminds me of a game by CompileHeart from a bit back.. But I can't remember what it was called... Something-something quartet or quintet? Anyway, looks fun.

Just a few qustions before I sign on for anything:

1. When our heroines transform, do they turn into the 10~14 year old magical girls, or do they retain their 30~ish bodies?

2. Will there be any obnoxious cute mascot-character(s) who work alongside/guide the heroines?

3. What 'type' of magical girl theme are you going for here? Is it along the lines of Sailor Moon where each girl has a "signature attack", or is it more free-form and varied like in Magical Girl lyrical Nanoha?

4. Are you aiming for more of a comedy, a drama or something grim-dark like Madoka with the story? Or a mix?

Those be all me questions for now~
