There has been No More Heroes and No More Heroes 2. They are, says series creator Goichi Suda, like emptying one's bowls. No More Heroes 3? That's like diarrhea, he says.
"With No More Heroes 1, the idea came when I was literally sitting on the toilet. It was the result of trying to empty my bowels, if you like," Suda tells the Guardian in a video interview.
