Detective Conan OVA 12: The Miracle of Excalibur (2012)

Overview

Professor Agasa asks Conan for a special favour: to come over to the Beika baseball park, where Ai and Agasa are already waiting. Here, Minae a baseball-playing young girl tries to compete in an otherwise all-boys team, but has a hard time of it. According to the coach she only seems to be lacking a bit of self-confidence. On her way back to the bench she stumbles over a baseball bat that the legendary player Matsui Hideki rammed into the ground. Supposedly any player who swings this bat gains the strength of a real baseball player, and with it any ball can be hit. Time for Conan to take fate into his own hands... for Minae's sake.
