Junko Enoshima

Junko Enoshima (江ノ島盾子 Enoshima Junko) is one of the characters featured in Dangan Ronpa.

Personality
A young woman who took the country by storm with her extravagant tastes. Junko wanted to be a model ever since she was a child, but is also eager to try new things. She used to be homeless, which was a very harsh environment. Junko's personality and mannerisms tend to be very erratic and unstable. Junko often switches 'personality' regulary which can go between angry, violent, happy and sad at random times. Junko is obsessed with despair and finds it to be one of the most enjoyable emotions of all time.

Pre-Despair Incident
Junko managed to begin a modeling career and quickly became an idol amongst the Japanese population, this created a lot of unwanted attention on her behalf as according to Mukuro who was at the time disguised as Junko claims that the only men who were interested in her were creeps that didn't actually care about her. She was later enrolled into Hope's Peak Academy along with her twin sister Mukuro Ikusaba. She was able to make 'friends' with her fellow classmates but was in fact a influential member of Super High School Level Despair along with Mukuro. The two of them began to scheme and plan the high school life of mutual killing in order to find 'true despair'.

High School Life of Mutual Killing
Junko worked behind the scenes and controlled Monobear in order to cause anxiety and paranoia between the students in order for them to kill each other. She also began to broadcast everything as a tv program for the public to enjoy and fall into despair. After Mukuro, who at the time was disguised as Junko, kicked Monobear, Junko decided to execute her in order to "set an example" as Mukuro's acting was quite bad and did not resemble Junko's true personality at all.

As Monobear, Junko was able to ensure the deaths of several of the students before realising that Kyouko had broken into the headmaster's office and stole the master key and Mukuro's profile. She then decided to break her own rules and stage a murder by using Mukuro's body. Junko almost succeeded in her attempt to kill Naegi and frame Kyouko but was proven fruitless when Kyouko saved Makoto and later Makoto not calling out Kyouko's lie.

Super Duper Nasty Torture
Junko goes through all of the previously shown executions: "Million Fungoes", "Motorcycle Death Cage", "Versailles style Witch Hunt Stake", "A Dozer Master", "The Space Journey", and she dies on "Detention". All the time through her executions she seems to have a relatively calm, bored, or sometimes even happy face. In "Detention" she has her huge smile on her face and holds up the peace sign, before looking up, at which point she gets crushed by the compactor.

Trivia
