Keisuke Itagaki’s manga is kinda funny looking and not really suitable for animation, so this anime version of his excessively violent tale of a kid with severe parent issues looks a lot tighter than the loose, fluid, if anatomically incorrect art of Itagaki’s.
Anyway, I saw this up to where he was fighting a mountain ape in order to train. I see in the manga he’s up to fighting a defrosted caveman called Pickle. This sort of madness tempts me to watch/read more.
