I just needed to say that if you're going to watch this, the first few episodes may seem pretty boring, but I need to tell you that it gets better. I was tempted to ditch it and move on to the next thing, but that was when it got interesting.
Also, if you're facing problems with being a shut in like me, this might help, and for others it can even give you more of a will to live so I understand where the value is to others.
Now in terms of the aspects outside of the story and characters, i'm not a good judge of because it doesn't always matter to me, but the inner voices of the characters can have somewhat of a different audio than in other anime, but it's not a big deal. hope this helped, enjoy!
