Seigi's university friend Shimomura introduces him to Okita Ayumi, another member of his club.
Ayumi has been looking for clues concerning her missing boyfriend.
When she visits Entranger, she presents her only lead: a turquoise earring.
Because her boyfriend went missing immediately after giving her the earring, she's searching for the store that sold it.
However, when Richard sees the earring, he behaves differently than normal.
Seigi becomes curious about what's going on inside Richard's head.
