Kariyasu Karasuba

**Kariyasu Karasuba** is a minor antagonist featured in *Danganronpa Kirigiri*. He is one of the Victims of the Twelve Zodiac Duel Noir Challenge and the culprit of the Museum of Medieval Torture Case.

## History

### Prior Life

Kariyasu was a university student that ended up dating a graduate school student named Shōko, as well as taking work at a convenience store. Shōko was a member of the university's European ancient history department and that was under Professor Fukuju Idogaki. Unfortunately, Shōko would be found dead and was deemed a suicide after finding the use of hydrogen sulfide. When he was approached by the Victims Catharsis Committee, he learned the truth after agreeing to take part in the Duel Noir. In truth, Fukuju killed her in order to conceal the truth that he was plagiarizing research papers off his students and she had planned to expose him. Angered, Kariyasu plotted his revenge as the culprit of the Museum of Medieval Torture.

### Museum of Medieval Torture Case

After the start of the Duel Noir, Kariyasu put his plot to action on January 11th. He got Fukuju drunk enough until he passed out and took him to a small cottage on the courtyard, nearby to the museum and locked him inside it. From there, with the use of an ice sphere on a headless iron maiden which was outside in the courtyard, he redirected the sun's rays from the sphere to the inside of the cottage. As a result, a fire broke out that burned Fukuju to death. Also, given the set-up, this allowed him to have an alibi since the fire broke out around noon of that day,

Kariyasu would meet Sachi Mizuiyama at a cafe later on due to arrangements thanks to Katana Shindō. When Sachi meets him, he's clearly unstable from the murder of his lover. Kariyasu explains how he and Shōko met, which was at a library, as well and delving into the situation surrounding her and Fukuju. When Sachi asks why, he responds that she's probably going to ask him that anyway. He delves into Shōko originally being Fukuju's assistant, Fukuju stealing credit for her work and her discovery that he's been doing such deeds for a while now without consequence. He said she considered such things a crime against humanity, but when Sachi points her strong sense of justice, it just earns her a bitter look from Kariyasu.

From there, he reveals how Shōko was murdered, which had Sachi ask how he knew for sure that Fukuju did it. Kariyasu rattles off the evidence that proved it happened, such as Fukuju being caught on tape buying sleeping pills. When Sachi asks if there was evidence why was it ruled a suicide, apparently the suicide ruling was declared first and the police never bothered to investigate properly. When Sachi questions that if he has this evidence why not present this to the police, he merely dodges the question (which confirms to Sachi the Committee was behind such knowledge and they target those unaware they've been hurt by the system). When Sachi asked if he was aware that Fukuju died, he mentions he heard at work and has an airtight alibi for it.

When asked if he could meet Fukuju one last time, Kariyasu admits he would say 'you reap what you sow'. Kariyasu says he heard Fukuju died as a result of a fire coming from his cigarette, and starts to laugh, which creeps Sachi out. She thanks him for his time and says she now has more of an idea of the truth of this case. Before she leaves, she asks for his birthday, which he reveals to be August 30th, thus making him a Leo and solidifying that he is the culprit of the Duel Noir. She leaves, though notes it feels as though his sharp gaze was still aimed at her.

Later on, Sachi relays her information about the Duel Noir to Yui Samidare via phone, despite her imprisonment. With his assigned detective being informed of his identity and how he did it, in accordance with the rules, it marks Kariyasu's defeat and its implied he will be arrested for his crimes.

## Appearance

Kariyasu has sunken cheeks with unkempt hair sticking out in all directions. He wears a cheap looking coat, alongside a shirt that has a stretched collar. Overall, it gives him a mentally unstable look.

## Personality

Like all other Victims, he was willing to to resort to murder over the one who had wronged him, in his case being his lover. Kariyasu despised Fukuju for the murder of his girlfriend to the point of laughter after hearing about the fire that killed him, considering such a thing as delivering Fukuju due justice. Still, the murder of Shōko seemingly had affected his sanity, as Sachi noted when she met him, with her being convinced overtime that if she pushed him to hard he might snap. Despite being clever enough to go about an elaborate form of murder, Kariyasu has shown to be overconfident in his trick being unable to be put together and is unaware that he frequently spills details that lends credence that he is the culprit to Sachi. Given his glare when Sachi brought up Shōko's sense of justice, it shows he's sensitive to those when it comes to a topic about his girlfriend's character.
