Masayo Aoshima

Masayo Aoshima is a 26-year-old employee at Beika Bank in Detective Conan. She is the older sister of Mina Aoshima, and the two sisters share an apartment at the beginning of the “Locked Bathroom Murder Case.” A devoted Yoko Okino fan, Masayo initially appears friendly and approachable, even offering Kogoro an extra ticket to Yoko's concert. Her complicated relationship with her sister and former boyfriend, however, reveals a more troubled side to her character as the case unfolds.
