👀 SPOILER-FREE SUMMARY

A character-driven mystery that trades rapid-fire deductions for something more personal. When a young boy named Kazuki Kinukawa arrives as the Detective Agency's latest client, the case shifts toward themes of family, identity, and the weight of unresolved pasts. Conan, Ran, and Kogoro find themselves drawn into a search that carries real emotional stakes rather than the typical crime-of-the-week setup. The pacing is deliberately slower here, investing in character relationships and the gradual layering of clues rather than rushing toward revelations. This is Part 1 of a two-parter, so expect groundwork — the episode builds atmosphere and establishes the emotional core of the mystery without tipping its hand. A strong entry for fans who appreciate when Detective Conan lets its heart lead the investigation.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

A Child Star's Request

Seven-year-old movie star Kazuki Kinukawa walks into the Mouri Detective Agency with a bitter mission: find the mother who abandoned him at a church, not to reunite — but to tell her he'll never give her a dime.

Conan Cracks the Postcards

While Kogoro flounders, Conan examines the old, dirt-stained postcards Kazuki's mother sent him and pinpoints her location as Atami — a quiet deduction that sets the entire investigation in motion.

The Beauty Mark Clue

Kazuki reveals a deeply personal detail: his mother has a distinctive beauty mark near her breast. It seems like a minor childhood memory, but it becomes the episode's most critical piece of evidence.

Kamoshita Checks In

Freelance writer Yushiro Kamoshita arrives at the same hotel, clearly digging into Kazuki's family background for his own purposes. His presence immediately raises questions about who else has a stake in finding the boy's mother.

Murder at the Hotel

Kamoshita is found strangled, and his cellphone holds a damning image — a woman with a beauty mark near her breast, directly linking Kazuki's missing mother to the killing and transforming a missing-persons case into a murder investigation.

📍 ARC CONTEXT

This canon episode follows the conclusion of 'The Tragedy of The Fishing Tournament (Part 2)' and launches a fresh standalone two-part case centered on young Kazuki Kinukawa's search for his mother. As Part 1, it establishes the emotional foundation and investigative threads that will be resolved in Episode 355, 'A Small Client (Part 2).' No overarching plot developments from the Black Organization arc, but the case offers meaningful character moments for the core Mouri Agency trio.
