if you haven't read the manga then this is probably a 10/10. it is a good story but they skipped complete arcs from the manga that were important to the development of the story. though there are some rumors saying that they'll put it in the second season so hopefully they will or only anime watchers are missing out on some good content. another thing i have to say is, dont watch the dub. Now im not one to judge people whether they watch sub or dub because i happen to be a dub watcher but the dub for this anime is awful. Tsukasa sounds like he smokes 10 packs a day. they didnt even try to make the kids sound like kids. the VA's are good and all but it doesnt match the character in the slightest. other then that, it is a good anime and the characters have depth. the series really leaves you at the edge of your seat the whole time and does a really good job of keeping the story on track.
