Miko Yoshinaga

Miko is courteous and knowledgeable when dealing with visitors to the shrine. She readily explains information connected with Hokkaido Toshogu and the historical objects associated with it rather than treating the detectives' questions as an intrusion.

Her characterization is closely tied to her duties as a shrine maiden. She remains outside the violent competition for the Onoe treasure and instead provides local and historical context for the investigation.

Miko has knowledge of Hokkaido Toshogu Shrine, its traditions and the historical material preserved or associated with the site. This makes her a useful source when Conan and Heiji begin tracing the history of swords connected to Hakodate.

She has no established combat or investigative abilities. Her contribution comes through local knowledge and her familiarity with the shrine rather than physical participation in the conflict surrounding the treasure.

Miko appears during the investigation into the unusual swords sought by Kaitou Kid. Conan Edogawa, Heiji Hattori, Ran Mouri and Kazuha Toyama visit historical locations around Hakodate while trying to understand why Kid has suddenly become interested in swords rather than jewels.

At Hokkaido Toshogu Shrine, Miko provides information that helps place the objects and clues within Hakodate's historical background. The investigation eventually links the swords to the treasure hidden by the Onoe family's first head.

The swords ultimately prove to contain clues that must be interpreted together with Hakodate's geography. Miko's shrine is one of the historical locations encountered as Conan and Heiji reconstruct the path toward the hidden treasure.

Conan Edogawa and Heiji Hattori meet Miko while investigating the historical clues connected with the swords and the Onoe treasure.

Ran Mouri and Kazuha Toyama accompany the detectives during their investigation around Hakodate.
