Case Closed Episode 424

👀 SPOILER-FREE SUMMARY

A standalone filler episode delivering one of Conan's classic self-contained murder mysteries. The setup is playful—Kogoro and Conan stumble into a case after a routine trip to a costume shop turns into a full-blown homicide investigation. The costume party backdrop gives this episode a slightly quirky atmosphere, but the tone shifts into familiar detective territory once the body drops. Expect steady, methodical pacing as Conan works through suspects and alibis while Kogoro fumbles his way toward the truth. It's a straightforward whodunit with no ties to the larger Black Organization storyline, making it an easy watch for casual viewers or completionists. The costume gimmick adds a layer of visual fun to the deduction sequences, but don't expect any major emotional stakes or character development here.
