OVA
Description
Karin Sarayashiki is a high school girl who becomes a participant in the deadly live-streamed game along with several other young people. Her background is that of a popular online streamer who specialized in playing horror games, a fact that initially defines her public persona. However, her real-life reaction to frightening situations stands in stark contrast to her digital expertise, as she is genuinely prone to panic and fear when faced with actual terrifying scenarios on the mysterious island.

In terms of personality, Karin is strong-willed and outspoken, frequently taking a direct and sharp tone with those around her. She is quick to resort to physical aggression, often using her fists to express annoyance or to preemptively strike at anyone she perceives as a pervert, which is demonstrated when she immediately punches fellow participant Akatsuki Iride upon their first meeting after waking up in an unfamiliar forest. Her initial interactions with Iride are marked by this combative nature, as she is easily irritated by his seemingly carefree attitude and lack of concern for the danger surrounding them. Despite her tough exterior, she is shown to be easily frightened, seeking comfort from others when she is scared, such as asking Himiko Inaba if she can hold her hand during a tense stage. This duality creates a character who is outwardly aggressive but inwardly vulnerable, especially when confronted with the real horrors of the game rather than the simulated scares of her former hobby.

Karin's primary motivation within the story is survival and escape from the game alongside the other players. While her initial role is that of a reluctant participant who is critical of her teammates, she gradually becomes a more integral and cooperative member of the group. Her specific expertise in horror games is not frequently used as a central skill, but her genre knowledge may inform her caution in dangerous situations. Her key relationships develop most notably with Iride. After an initial misunderstanding where she constantly berates him, she eventually apologizes for her earlier behavior and begins to show concern for his wellbeing, even waking him up to accompany her out of fear and later expressing relief at his safety in an emotionally confusing manner.

Throughout the stages of the game, Karin shows signs of development. She moves from being a distrustful and antagonistic figure to someone who participates in group strategies, albeit while still maintaining her blunt demeanor. For instance, during a stage involving a mimic monster that disguises itself as her, she is infuriated to learn that it got close to Iride, revealing a possessive or protective inclination that had not been evident before. Her notable abilities lie not in any supernatural skill but in her physical aggression and her straightforward, no-nonsense attitude that allows her to kick unhelpful teammates out of a cooking area to get a task done efficiently. Ultimately, Karin is characterized as a horror game fan who is ironically ill-equipped to handle actual horror, using a tough, punch-first attitude to mask her deep-seated fears while slowly learning to trust and rely on her fellow captives to survive.
