Enju Otsuka

"...I am not Japanese. The Major saved me in the middle of the war. Since then, I have been serving him as a soldier. My whole family is dead. He gave me the chance to live again."

- Danganronpa: Trigger Happy Havoc.

Enju Otsuka (大塚 炎珠) is a student at Hope Peak Academy's Class 78th and participant of the Killing School Life featured on the first role-playing game of Danganronpa. Her title is Ultimate Soldier (超高校級の軍人, lit. Super High School Soldier), replacing Mukuro Ikusaba from the original game.

Appearance
Unlike her counterpart, Enju presents herself as a rather short girl with a light and thin complexion. She wears a red scarf around her neck that looks worn out over time, something that was given to her by Keichiro Otsuka, her adopted father, and it was the only thing that was left of her after her execution. She has very long hair in a shade of red-orange that is tied in a single thick braid kept on her back and her bangs are peaked above her big, sharp pink eyes.

Despite her short stature and cute appearance, Enju is described by Yukio Shizukane as someone with an extremely frightening aura.

Personality
Enju was awfully quiet all the time and talked very little with other people. She was also very suspect by everyone and just talked to the people that she didn't consider a potential threat to her, like Amaya Hayama or Anna Kiryuin. It was quite hard to know what she was thinking due to her iron mask that covered her emotions and thoughts, to worse the situation. Thanks to that, it is given the impression that she was not worked well in the game since she didn't talk with Yukio Shizukane, the protagonist. Still, she shows a more sensitive side as she cares a lot about the only family she has left, as well as a certain delicacy in liking gardening.

It is revealed that she cared a lot about her adoptive father because he saved her from death and that is why she started serving him as a soldier, to pay him for his cares towards her, even although he didn't want her involved in military. After Yukio proved that Ryo Fukukado couldn't be killed by anyone besides Enju, she gave up trying to prove that she was not the killer and even made Anna stop doing so, accepting her death as she said as she just wanted to see her father again.

Talent and Abilities
As the Ultimate Soldier, Enju had immense strength, speed and agility, as well as vast knowledge about how to use a variety of different weapons. She carried a knife holder in her left thigh which she used to hide the kitchen knifes in her plan to kill Ryo. She also showed a level of intelligence and forged many evidences in Ryo's room to confuse the students. Also, when she presented herself to Yukio and Amaya, she could smell blood in the second floor of the dormitories.

Early life
As a child, Enju was saved by Keichiro Otsuka who adopted her as his own child. She was created by him and her current name was given by him since she doesn't remember her former one. She wanted to be helpful to him and thank him for everything he had done for her, so she entered his military group as a soldier. Enju was not that strong before but she was determined to be useful to her adoptive father, and so, she trained hard, gaining attention of the entire country and world with her talent. Before being invited to attend Hope's Peak Academy as the Ultimate Soldier, she used to attend Ash Garden High School (灰園高校).

Killing School Life
Enju was among the sixteen chosen to attend Hope's Peak Academy, but she was trapped inside the school. She was then found by Yukio and Amaya as they were knowing everyone properly and exploring the building. She was nearby the stairs to the second floor of the dormitories and just talked to Amaya as she didn't trust Yukio. She said to them that she smelled blood stairs above, scaring both. She was then there when Monokuma presented their eternal school life. She was also there when he also presented their motive videos.

Her motive video had her adoptive father, Keichiro, making her upset and worried about him. Knowing this, Amaya suggested she kill someone for her, Ryo Fukukado, who was in possession of something that she wanted. Amaya took advantage of her desperate state to make her murder Ryo, also getting to keep his file about The Tragedy and Ultimate Despair. She was then found out by Yukio and, even with Anna's attempt to get her free, she gave up and explained everything about the case, but omitted that Amaya had participated in the plan. Afterwards, she was finally executed by Monokuma and her blooded scarf was everything left from her.

Creation and Development
Enju was meant to be as a English soldier who serves the queen: very quiet and tight-lipped who didn't trust anyone, but Miika found that too edgy, so she put Anna to be her only friend. All the thing about she being manipulated by Amaya was meant to be revealed at the chapter one as the author imagined the betrayal between them, but she found more interesting if everyone found out about it just after she was murdered in chapter five, making them question about her honesty with everyone, including the protagonist.

Her last name (大塚) means "big mound", making reference to her overall abilities in combat and strong sense of smell. Her first name means "fire jewel" (炎珠) and makes reference to her execution, "Wild, Wild Gemstone", and her hair color that is like fire.
