I can already see the white and black QBs conspiring some grand scheme, and it will probably be epic in the end? So this story is indeed quite multilayered and has a ton of potential, behind the facade of an excellent yuri comedy. I mean at this point it's not hard to get that they're trying to harvest girls' power for some purpose, and the stronger the power is, the better for them, just like what the original Madoka QB was doing. I'm quite looking forward to what twist the author puts on this and how it ends.
