I gave this series a 5/10
It has a good plot, good story, a lot of funny stuff with serious bits despite being a ridiculous idea.
However, the presentation was horrid. Too much focus on fanservice, and not enough on plot.
Look at the ending for example. Completely skipped the ending fight scenes. Most likely because they spent too much budget on the fanservice, and just ignored the fight scenes.
If they actually explored the plot a little more(as well as the growth of satou, which I was really looking forward to) It would've been a much better series.
Another failure of a light novel to anime adaptation.
Should've not held my hopes so high for an unknown studio.
