Junko Enoshima

At the end of the Killing School Life in Danganronpa: Trigger Happy Havoc, Junko appears to be a young high school-aged teenager of 19 years, but due to her causing her classmates memory loss, she is two years older than they all believed her and themselves to be. She has a tall, dramatic hourglass figure, light blue eyes, and long, thick, bleached strawberry-blonde hair tied in two twin pigtails. Due to her fake talent, she wears heavy make-up along with fake long red nails.

Due to being related, Junko and her older twin sister Mukuro Ikusaba share several physical characteristics. However, Junko has a considerably larger chest than Mukuro and weighs two pounds more than her. Junko's eyes are more round and larger and are blue with her contacts or naturally red compared to Mukuro's light purple eyes. Junko also lacks freckles.

Junko's usual outfit includes a black cardigan over a white dress shirt, with both left open to the third button to expose the top of her black-and-red bra, a red pleated miniskirt that is cut extremely short, and mid-sized black boots with platform heels and red laces. Her cardigan is accented with white symbols of her Former High School. She accessories with a long tie that hangs loosely around her neck with a design alternates between pure white (Danganronpa 3) and as half black and white with a prohibition sign on it (Danganronpa 1) that hangs loosely around her neck, a thin black choker, a red bow above her left breast, and two buttons on her right side.

Her most notable accessory is her signature twin bear hair clips that are based on Monokuma's two sides. The right clip is a completely white bear with dot eyes and a neutral expression, while the left is a black bear with a white muzzle, jagged red eyes, and a wicked smile (Danganronpa 1). During her time at Hope's Peak Academy (and overall in the Despair Arc) she instead wore a set of hair clips of a cute white bunny and a large red and white bow.

Due to her constantly-shifting personalities, Junko's appearance shifts slightly with her mood. Junko's "moods" included (but were not limited to) her Monokuma persona, sickening cuteness, severe depression, clinical sophistication, boisterous vulgarity, eerie stoicism, and haughty superiority. Her "haughty superiority" personality dons a small gold and red crown with encrusted jewels. Her "clinical sophistication" personality wears glasses and styles her hair in a ponytail, carrying a pen and board. Her "severe depression" personality sports a few multicolored mushrooms on top of her head with a blueish forehead with no pupils. Additionally, her right hair clip has a sad face. Her "sickening cuteness" personality simplifies her entire appearance to appear more cartoonish, including smoother pigtails, large, bright eyes, and a small smile. Her "boisterous vulgarity" personality is similar to Genocide Jack, as she has a reddish forehead and she talks with her tongue out, along with having messier pigtails and doing the hand-horn gesture. Her "eerie stoicism" personality involves her doing a pose that turns her body away slightly to the left with one arm around her torso and one covering part of her face with a constant serious expression. Lastly, her Monokuma personality involves her having Monokuma in front of her.

In Danganronpa 3: The End of Hope's Peak High School, she temporarily wore a cheetah-print dress with a pale yellow fur collar and cuffs, a thick black belt with a sliver buckle, a thigh band which is quite similar to her choker, and black shoes with heels. She accessorizes with brown sunglasses with deep pink lenses and the same set of hair clips when Mukuro posed as Junko, a cute white bunny and a large red and white bow.

She is also seen with the Hope's Peak Academy's uniform. She wore a bleached brown cardigan over a white dress shirt, unbuttoned to expose her half of her bra, a pure white tie tied loosely, a navy blue pleated skirt, and mid-sized black boots with platform heels and red laces, with the same bunny and bow accessories. Her cardigan is accented with buttons of her Former High School.

In Danganronpa Zero, it is stated that she looks much more average without her make-up. Her alternate identity, Ryoko Otonashi, has dark red eyes, matching the color of her long, disheveled hair, which contrasts with those of Junko. It remains unknown which hair and eye color represents Junko's natural appearance.

In (chronologically) earlier installments of the series, such as Danganronpa Zero and Monaca Towa's flashbacks in Danganronpa Another Episode: Ultra Despair Girls, Junko is seen in the third variation of her Hope's Peak Academy outfit. Her cardigan has been removed, and her dress shirt is buttoned up to hide her bra. Her red bow tie is pinned on the left side of her dress shirt, and her right pigtail is held by a black bunny clip with red eyes. She also wears a black miniskirt and a new tie that lacks the circled X and has a different balance of white and black; the collar and knot are white, while the rest is black. Junko's nails are still painted red, but they are much shorter than in her other appearances.

As a young fashionista, Junko Enoshima is described as simply "not fake", charismatic and eager to try new things. During her first appearances, she comes across slightly air-headed and hot-tempered. In the official artbook, she is described as a person who "drips with dissatisfaction the moment she opens her mouth" and tends to be in trouble with her classmates. She is also mentioned to be a bit too talkative with an overly carefree attitude.

However, Junko's real personality, revealed at the conclusion of the Killing School Life, is notably different: very apathetic and easily bored to an unhealthy and abnormal degree. Because of this, her behavior and mannerisms tended to be extremely erratic and unstable by her own autonomous design; keeping up one "appearance" for too long bores her, which causes her to often switch between her aforementioned different personas. She switched between these personas regularly, often imitating other students' expressions, which made for a highly unsettling conversation with the survivors. Her voice will either have a different tone or accent within the switches, such as "haughty superiority" giving her a voice similar to a stereotypical British monarch, her "sickening cuteness" giving her a higher pitched voice, her "clinical sophistication" giving her a more mature or deeper voice, making her speak as if she was, as her appearance suggests, a teacher/professor, her "severe depression" giving her a more sad voice, as if she was on the verge of crying, her "eerie stoicism" giving her a monotone voice, her "boisterous vulgarity" sounding similar to a stereotypical rockstar, and her Monokuma one mimicking his voice. While entering the Hope's Peak Academy as one of Class 78's students, she often talked as if narrating a story, writing down her thoughts in a notebook.

Above all, Junko was deeply obsessed with despair, having found despair to be the most (and possibly the only) enjoyable emotion for her, whether it be inflicting despair unto others, or suffering from despair wholeheartedly. This made her extremely dangerous, as she wished to make the whole world feel absolute despair. However, this also often proved to be her biggest weakness, as she gave her opponents a "fair" chance to defeat her in order to make their despair all the greater if they fail, and happily welcomed her own despair if her plans failed.

Both Junko herself and the game's creators have confirmed that she truly has no reason to do the things she does other than despair itself, which makes her all the more dangerous and unable to be reasoned with. However it is hinted at in the anime that her analytical talent was what caused her to turn to despair, and that Hope's Peak was her first target because they see talent as hope, and use that talent for their own benefit, which drove Junko to take the talent they loved so much and use it for evil, which shows her in a more understandable light. It's also shown that under her amnesiac state, Junko doesn't show a thirst for despair or particularly strong hatred of boredom, implying that her constant case of forgetfulness had spared her from embracing despair again. However, the return of her memories reverted her to her former ways.

As the mastermind and leader of Ultimate Despair, Junko was shown to be highly intelligent, cunning, somewhat impulsive, extremely manipulative, and violent and cruel without remorse. She was a highly toxic individual, being both physically and mentally abusive to everyone around her. She manipulated people into falling madly in love with her and used their weaknesses, their despair, against them. Things like hope, peace, and happiness disgusted her, but she sometimes gave hope to others, only to turn it into greater despair later. She often manipulated people into doing bad things instead of directly doing them herself and then had a habit of blaming these manipulated people and claiming it wasn't her fault, as a part of proving her point that despair exists in everyone and that hope will naturally lose to that despair. While she is very skilled, Junko can also lie and cheat to further her own goals, even if it's hypocritical and goes against her beliefs. It should be noted that even though she claims despair is the great unknown, in the end, the road of despair went exactly the way she had planned.

Despite that she can be cruel and abusive to some, Junko is actually capable of feeling love to those she's close with, however due to how far despair has driven her, she kills them anyways to cause herself to feel large amounts of despair.

According to Kodaka and Junko's voice actress, her personality in Despair Arc is a more natural version of her, closer to her true self and more neutral, before she started changing her personalities regularly. This seems to imply that her behavior in the first game is a result of decreasing mental health and deeper sinking into despair, explaining her more jaded and apathetic personality. This also implies that even the Tragedy was beginning to bore her, as the seemingly chaotic event went just like she planned.
