Is Danganronpa scary?

It’s not scary at all. If you describe it in one sentence:

Although one group of people and another group of people are doing the same thing, because they represent different nouns, He insists on distinguishing good from evil.

That’s pretty much what it’s about, so it doesn’t matter what the story is. I recommend watching it at station b, where you can listen to the voice actors and complain at the same time.
