Junko Enoshima (in Japanese: 江ノ島 盾子, Enoshima Junko) is the main antagonist of the Danganronpa franchise.
In the video games, she was titled Ultimate Fashionista and founder of Ultimate Despair. Junko has a hidden talent, known as Ultimate Analyst. She is the younger twin sister of Mukuro Ikusaba and had an alternate identity known as Ryōko Otonashi, which her memories were lost and counts as a different person that was not in any of the games. In the games, she controls and interfaces with the victims of the killing games through Monokuma and serves as the archenemy of Makoto Naegi. Despite executing herself in Danganronpa: Trigger Happy Havoc, her influence and legacy are ultimately the driving forces behind every installment's major conflicts.
