Conan reveals Shuhei Aosato is the name spelt when the Kanji of Fish is removed from the dying message. He reveals Aosato cut Akamine's diving regulator and leaves her on the island after promising he would return with help. After she died Aosato returns and exchanges the regulator to hide the cut and uses Akamine's regulator to leave, causing her lipstick to appear on his face. Aosato confesses his crime and reveals Akamine caused the death of their past companion Yoshirou and he murdered her in revenge. Aosato then unveils his knife and holds Ayumi hostage demanding an escape route. Subaru disarms him and saves Ayumi from Aosato who is later arrested. Later that night, Subaru is seen drinking bourbon whiskey.
