The harem rears its ugly head. All four of Mochizuki Touya's female comrades are in love with him. There is no issue with multiple wives in this alternate world. Touya decides to marry them after consulting God and the Goddess of Love. He has to wait until he's eighteen though, he isn't a freak.
Francesca is a robot that Touya met in the last volume. Touya can talk to the person who created Babylon, the floating base through technological hijinks. It's a recording from 5000 years ago, but Touya can speak to it since the recorded person knows the future.
Thanks for reading my review, and see you next time.
...And the series has officially devolved into ALL THE WAIFUS FOR PROTAGONIST-KUN as they all demand to be his wives (because polygamy is ultimate wish fulfillment material apparently) and I'm losing interest. Also, why is Cesca a walking kink library?
Please, please, PLEASE, PLEASE, get back to the magic, monsters, and clever gimmicks, and not this shallow romantic crap.
