No, there's not. They made the anime for the first game but not enough people liked it so they didn't make one for SDR2. There's Danganronpa 3 (Future, Despair, and Hope) and there's SDR2.5, but both are REALLY spoilery for the second game. If you're looking for more Danganronpa, I'd recommend either playing the games (because they came first before the anime) or watching playthroughs on YouTube. There are some pretty good ones. NicoB is my personal favorite. Because the games are the originals, they have a lot more detail and important information, and they're just better in general, in my opinion. Then you should watch Danganronpa 3, alternating between Future and Despair, and then watch the Hope arc, and then SDR2.5.
