At first, I was thinking this would have nothing to do with hentai. I was...wrong. Well, it didn't actually show anything graphic. I knew it would happen when he mentioned what happened to Japanese schoolgirls. I just love this animation. They look so funny.
Everything's been parodied with anime nowadays. Bob has the funniest design. Even your non music videos are loops! I love how it looks like they're ready to battle. It's as cute as a hentai related cartoon could be.
