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.
But I do think they could use 
a taste of their own medicine.
لكن أظنّهم يمكنهم أن يتجرّعوا
Aber vielleicht sollten wir sie
mit ihren eigenen Waffen schlagen.
Creo que sería apropiado que ganaran
una retribución ridícula.
Lo más apropiado sería
ofrecerles algo de ridículo.
Il doit y avoir moyen de se venger
à la hauteur de leur bêtise.
Ma penso che sarebbe giusto dar loro
un assaggio della loro stessa medicina. 
Mas eu acho que podem sentir
Но можно заставить их наступить
на собственные грабли.
