Kenta Oosawa

Kenta is loyal to his friends and concerned about Satoshi's disappearance. He cooperates with Conan and Heiji as they question the children about what they know.

His characterization remains deliberately simple because he appears only within the OVA's missing-child case. The story establishes his friendship with the other children more clearly than any independent hobbies or ambitions.

Kenta possesses no special abilities. He is an ordinary elementary-school student without detective or combat training.

His contribution is contextual: because he knows Satoshi personally, his recollections help the investigators understand information connected to the missing boy.

Kenta appears during Conan and Heiji's investigation into the disappearance of Satoshi Moriguchi. Together with Mayumi and Mikihiko, he helps provide the personal background needed to interpret Satoshi's clues.

The children's testimony gradually helps the detectives narrow the search while the true danger surrounding Satoshi becomes clearer.

Satoshi has been kidnapped amid events involving two bank robbers. Conan and Heiji eventually determine that he is being held at his former home and intervene to resolve the case.

Satoshi Moriguchi is Kenta's friend and the child whose disappearance drives the investigation.

Mayumi Esaka is one of Kenta's fellow elementary-school friends.

Mikihiko Yagi belongs to the same group of children as Kenta, Mayumi, and Satoshi.

Conan Edogawa speaks with Kenta and the other children while searching for Satoshi.

Heiji Hattori works alongside Conan to determine where their missing friend has been taken.
