As to be expected from Studio Trigger this anime is absolutely GORGEOUS. The animation is top tier and did I mention how beautiful it was? Cause it is. As soon as I finished it I started looking for wallpapers.
My only problem was that it didn't explore some of the more interesting parts. Like, what's with the female thing? Are the main girls parents no worried? Like at all? It didnt take away from the story or anything, but it's to be noted.
12 episodes long, it gives you a satisfying end, and it's a fun watch. Give it a try!
