Yuri is the Game Changer of this season 2. She is the representation of how shitty human is. She spreading hate through her method of Revenge. She doesn't believe in second chance. Everyone needs to taste their own medicine as soon as possible. Junko is her first creation the Hate and Violence.

Nanno is giving us how good her intention is, you can have a second chance in life if you realize and admitting your mistake. But she also giving us her weakness in this season Guilt and Pitied.
