I found this anime to be rather attractive for many reasons. It points out a real social problem in Japan but also has a real human aspect that shows the world of Japan through the eyes of a hikikomori. In this case, they’ve done a great job really throwing a twist into the story by adding conspiracy into the mix. Be there is one or not, this is a great anime to learn a lot about Japan in general from an Anime.
Click on the image to play the episodes (You won’t leave the page) – I have %95 of all the episodes here except a couple that just are not available on YT. There are a few places to find these, sadly, the very last part of the last episode is not available. Try going to free dubbed anime or another similar site to see the very end.
You can see more Anime here.
PS: These keep getting removed, when I find them again I’ll fix it.
