Do you know what to do when your shoe steps on some real nasty shit?
Take the shoe off? Don't be a dumbass, you cut the fucker off. And that's how the book goes: When you touch some nasty shit with an appendage, you hack it off. Pain don't hurt, and it's just the usual twisted logic. It's not as sexual (But it does have some twisted sexual content to make your scrotum clench in disgust) or as perversely funny as some (One) of his other works but it's still not that bad. Your time could be better spent reading a chapter of something good but some Shintaro Kago will make you appreciate the good stuff even more.
