It tackles some big issues in modern japan and how Satou goes through them.
Even though alot of unfamiliar terms might pop up as you watch this series, you'll be very familiar with them by the end of the series if it's been subbed good.
This anime kept giving you hope only to drag you down and make you depressed and this kept hapenning throughout the whole anime.
I kept thinking "ohh why don't you do that, or that Satou!".
But having said that, alot of very interesting topics came up, and the reason I felt depressed was because you get very attached to the characters, and bad things keep happening to them.
It's about how they react and deal with all these bad things that happen, and how they move on.
The anime constantly surprised me, you never knew what was going to happen next!
There are some very strong feelings involved, so be prepared before you watch it, it's really heavy.
I can't really label what kind of genre it is, it doesn't stick to just one, it ventures between many different genres.
All in all it's a great anime if you like very emotional animes.
