Danganronpa 2: Goodbye Despair Anniversary Edition

As the description states, you have to complete a single class trial (before and after the intermission is what counts as a complete class trial) without losing all of your Influence and having the entire class choosing you as the Blackened. If you play on the Gentle difficulty, your chances of getting this are easier, as the misleading Truth Bullets/Blades won't be as numerous and the white noise will not appear.
