The review:

Surprise, surprise this manga has been purged from the site. Hilariously enough, Tsugumomo is untouched. But hey, what can you do? Controversy is one thing, popularity is another.
I encourage you to give this series a read. It's worth something. Good, smart manga that covers a lot of things.
