Nerima Daikon Brothers is a fantastic anime from the makers of Excel Saga and Puni Puni Poemi. It's one of the few anime that I'll recommend the dub for, if only because the songs (did I mention it's a musical series) are hilariously dubbed (intentionally).
Sadly, there's next to no hentai/R34 of NDB, so I've done my part to rectify that. I will likely revisit the series later, but for now this is enough. Please note that these are old pics, and yet, to my knowledge, the most recent NDB hentai out there.
