The murders pile up faster than the explanations, and Akechi's brilliance only deepens the paranoia instead of solving it. Kobayashi gets pulled into a detective's logic that treats every student as a suspect and every motive as plausible. This isn't a mystery that rewards you for guessing right, it rewards you for watching someone smart enough to see connections nobody else can, and corrupting enough to act on them. Eleven episodes is barely enough time to watch the rules of the game shift beneath your feet.
A string of brutal murders rocks a prestigious middle school, each crime more disturbing than the last. When the brilliant detective Akechi arrives to investigate, he encounters Kobayashi, a curious student who insists on becoming his assistant. What begins as an unlikely partnership quickly spirals into something darker. As they dig deeper into each case, a pattern emerges that suggests the murders are connected by something far more sinister than random violence. The killer operates with calculated precision, and the logic behind their crimes becomes increasingly twisted. Kobayashi finds himself drawn deeper into the investigation, discovering that his own connection to the murders runs deeper than he ever imagined. The line between detective and accomplice blurs as the psychological games intensify. Every clue raises more questions. Every answer brings new horror. The series questions whether solving a mystery means uncovering the truth, or simply justifying what's already happened. For viewers who crave mystery that genuinely unsettles rather than simply entertains, this psychological thriller demands your attention.
