Detective Conan (Case Closed) Season 1 (Episodes 1–28) marks the gripping origin of the world's most famous pint-sized detective.
While every episode features a mystery, these are considered vital for character introductions and overall series lore:

From episode to episode, the world outside remains as cruel and clever as ever: a murdered heiress whose shadow was her killer, a rogue art thief who vanished into moonlight, a diplomat's son poisoned mid-conversation, a haunted mansion where the victim's dying message traced a name in blood. Each case is a locked room, a broken alibi, a whisper of betrayal hidden behind a smile.
Episodes 19 and 20, "The Elevator Murder Case" (a two-parter in some counts, though often listed as 19), introduces a major foil. While not the famous Heiji Hattori, these episodes refine the police line-up, specifically Inspector Megure, who grows from a skeptical authority figure to a man who trusts "Kogoro’s" strange sleeping deductions.

A hallmark of Case Closed is that murderers are rarely monstrous. In these first 28 episodes, victims are often bullies; killers are often victims of circumstance. Episode 8’s art museum killer? A curator trying to protect art from a corrupt director. Episode 26’s ("The Dog, the Car, and the Gun"), a revenge story. You root for Conan, but you often pity the culprit.

Episode 5 ("The Shinkansen’s Bombing Case") features two unnamed agents, Gin and Vodka, in a tense cat-and-mouse sequence. Episode 13 ("The Strange Person Hunt Murder Case") introduces the enigmatic and terrifying Ai Haibara? No—she does not appear until much later (Episode 129). Instead, Episode 13 and the episodes leading to 28 focus on the fear of exposure. The most significant early serialized arc is the introduction of Conan’s ally, Dr. Hiroshi Agasa, and the first appearances of the Black Organization’s operatives. Episode 18 ("A June Bride Murder Case") shows Conan using a voice-changing bow tie to save a life, a reminder that his gadgets are tools for survival, not just tricks.
3.1 Conan Edogawa: The Tragic Hero In these first 28 episodes, Conan is characterized by a palpable frustration. Unlike later seasons where he becomes more accustomed to his new life, early Conan is desperate. Episodes often feature internal monologues where he laments his inability to act like an adult. This vulnerability makes him relatable; he is not infallible. For instance, in "The Valentine Murder Case" (Ep. 6), his failure to prevent a second death weighs heavily on him, humanizing the detective archetype.
