This is one of the only animes that did not give me much of an impression after I left, though. So I am just going to list my opinions of its pros and cons. I will leave out parts that aren't too good nor too bad.
Pro:
Non-generic MCs= (genius siblings, one of them being a human
supercomputer and another who can manipulate
emotions really well)
Art= Rated 9. One of the best art I've seen. It's really bright, and it stands
out. I would have rated it 10/10 if it weren't for Hibike! Euphonium.
Story= It could have been 9/10 (I'll talk about weakness in cons), it's really
funny sometimes, filled with great strategic twists and insights about
life/human nature
Con:
Steph= I have never been bothered by something in a TV show so much as
this. The way the 3rd protagonist in the anime (not manga) is
treated just gets me upset for some reason. Although it is shown
that she is clearly capable of a lot, she is usually only as fan-service
, a test subject, or a servant.
Story= Story was great. The only thing is the ending. I'm not complaining
that the ending was too open, but that it ended on the wrong note.
If the producers have removed the scene with the elf and her slave, it
would have a much better closure, and focus on the next season.
Other notes:
A ton of ecchi/potential hentai material ( ͡° ͜ʖ ͡°)
Music is by video game music creators
A lot of references to different things e.g. (Laputia:Castle in the Sky)
Verdict: Watch it. It's really entertaining, and decently memorable. Characters are all pretty interesting and fun. A ton of awesome fan-service going on (I feel as if I'm he only person who likes fan-service :\). Overall, I give it an 8.
Edit: I literally just noticed that this is categorized as ecchi. This actually surprised me, since most ecchis don't have much plot going on
