Ishimaru

Ishimaru is a Danganronpa fan game created by Tumblr user radical-6. The game was first posted on Tumblr on April 9th, 2013. Three years after making the post, OP removed the download for the game, claiming in an edit, "this game was a mistake and I took it off the internet because it’s 2016 and I can’t have this bad gremlin characterization that I did three years ago in my life anymore."
