"Goth" is a psychological thriller manga written and illustrated by Otsuichi, based on his own novel of the same name. The narrative revolves around two high school students, a boy and a girl, who share a morbid fascination with death and the macabre. The boy, whose name is never revealed, and the girl, Yoru Morino, are drawn to gruesome crimes and often find themselves investigating murder cases out of curiosity rather than a sense of justice.

The story is structured as a series of interconnected vignettes, each focusing on a different crime or mystery. The boy and Yoru frequently cross paths with serial killers, psychopaths, and other dangerous individuals, often placing themselves in perilous situations. Despite their shared interest in death, their motivations differ. The boy is more analytical, seeking to understand the minds of killers, while Yoru is emotionally detached and seems to derive a strange comfort from the darkness they encounter.

One of the central arcs involves a serial killer who targets young women, leaving behind severed hands as his signature. The boy and Yoru become entangled in the investigation, leading to a tense and unsettling confrontation. Another notable storyline explores Yoru’s past, revealing her connection to a traumatic event involving her twin sister, which has deeply influenced her fascination with death.

The manga delves into themes of obsession, morality, and the thin line between fascination and complicity. The relationship between the boy and Yoru is complex, characterized by a mutual understanding of their shared darkness but also a sense of emotional distance. Their interactions are often tinged with ambiguity, leaving their true feelings and intentions open to interpretation.

"Goth" is notable for its dark, atmospheric tone and its exploration of the psychological underpinnings of its characters. The crimes depicted are graphic and unsettling, serving as a backdrop to the protagonists' exploration of human depravity. The manga maintains a neutral, almost clinical perspective on its subject matter, avoiding overt moral judgments and instead allowing the reader to draw their own conclusions about the characters and their actions.
