Minae is a young baseball player striving to compete on the all-boys team at Beika baseball park. Her lack of self-confidence hinders her performance, as noted by the coach. During training, she stumbles over a baseball bat once owned by the legendary Matsui Hideki. Local belief holds that swinging this bat grants a player the strength to hit any ball successfully. This encounter becomes central to her development. With assistance from Conan Edogawa, who intervenes to support her progress, Minae works to overcome her self-doubt through the bat's symbolic promise. This experience represents her primary character growth within the narrative.
