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.

Several brutal murders strike a middle school, and genius high school detective Kogorou Akechi comes to investigate. Student Yoshio Kobayashi wakes in his classroom to find his teacher mutilated and the weapon in his own hands, yet the curious, detached boy is quietly thrilled at being framed. With his long-suffering friend Souji Hashiba agreeing to help, he sets out to clear his name. Meeting Akechi sparks a strong mutual interest, and Kobayashi volunteers as his assistant while Akechi tests whether the eager boy can keep up. Loosely drawn from Edogawa Ranpo's stories, the show is a surreal psychological mystery full of bizarre, violent crimes.
