Nearly anything goes in anime! It's not like TV shows where if the content is a little offensive and it get's canceled. And there would be no book or manga to look forward to in place of it.
To my friends- I claim I could stomach weirdness in anime. But there's still room for something I wish I could un-watch.
I don't hate this one series, yet I still wish I could un-watch Bludgeoning Angel Dokuro-Chan.
What about you all?
