Giorno takes the arrow that Bucciarati and the others had acquired and stabs Golden Wind with it during the final battle with Diavolo. Golden Wind evolves into Golden Wind Requiem and doesn’t even allow Diavolo to reach the truth of “dying” and he is forced to meet an end that never truly has an end.
I'm terribly sorry for 
losing my composure...
...أنا آسف جدّاً لفقداني رباطة جأشي
Bitte entschuldigen Sie,
ich habe die Fassung verloren …
Siento haber perdido la compostura…
Siento haber perdido la compostura…
Navré, je perds mon sang-froid.
Mi perdoni... per la mia mancanza di contegno...
Desculpe por perder a compostura...
Простите, я не сдержался…
