Ashura is a human drama describing a famine in the medieval period of Japan. The depictions of cannibalism in the manga arose controversy and the manga serialized in Weekly Shonen Magazine was banned in some area in 1970.
I've never heard of a manga like that... is this the first time something so sick will be animated? (excluding hentai)
I'll watch it, sounds interesting (not because of the cannibalism... I'd rather not see that xD..). If it's too much for me I can always stop watching.. :)
