When the lighter was relit, Polpo's Stand, Shadow Sabbath, appeared and attacked. Giorno is able to see through Shadow Sabbath's weakness and faces it alongside Koichi. Koichi realizes that the arrow is involved in this situation and they realize that the point of Polpo's exam is to try to create more Stand users.
I don't know about the origin of the arrow,
،لا أعرف شيئاً عن أصول السّهم
Ich weiß nicht,
woher der Pfeil stammt.
Desconozco el origen de esa flecha,
Desconozco el origen de esa flecha,
Va savoir d’où vient la flèche,
Non so quale sia l'origine della freccia,
Não sei de onde vem a flecha...
