I would have thought that news articles announcing the series' adaptation would be spoiler-free, but no. The Crunchyroll news article for that has either accidentally or deliberately included artwork samples from the games which contain super high school level spoilers. As in massive, massive spoilers for things that were the greatest mysteries of the game, which people deliberated on all the way through the gameplay. "The culprit was [name redacted]" level spoilers.
They even included some pictures and clips from Dangan Ronpa 2, which the writer had done a previous game announcement news article on. That's so lazy.
Shame on you, Crunchyroll!

Anyway, since Dangan Ronpa is getting an anime, maybe Dangan Ronpa 2 will get one eventually as well? I would love to see that, too. I imagine that Dangan Ronpa's anime will get pretty popular. Sales will probably be good.
