I read its manga some time ago and found it very interesting, never thought it would have an anime adaptation.
The problem of the anime adaptation is the time: they're explaining only the most important parts of the manga in just 1 min. Another problem is that if you haven't read the manga, you'll be very lost. Everything is happening super fast (as was to suppose) that you can't understand what is going on.
The art and the characters are awesome, they're cute and well drawn.
Another thing that disliked me was the voice of the female character... They did not complement each other, I mean,
the girl has an innocent and cute face but its voice says the opposite. It's like the voice of some male child.
In conclusion, I think that the anime has been made to advertise its manga.
It's a shame that a nice manga is just having a few short episodes...
