I agree with her taking Kumo and Homura as her wives, but I don't feel right about Aika, there was no setup, she was just her maid harbored secret feelings. it would've been better if she just kept Aika as her close friend and aide, an assistant
Friends, when you add a harem to a series, it spoils the series. I'll read it some more and if I don't like it, I'll leave it (at least it spoils it for me)
