Joining the Gang (ギャング入門 Gyangu Nyūmon) is the fourth story arc in Vento Aureo.
Giorno protects Polpo's lit lighter as part of his test, but Koichi complicates Giorno's task when he enters Giorno's room in search of his passport. When the flame is extinguished by a passing janitor, Black Sabbath appears, taking an Arrow from its mouth and stabbing the janitor with it. The janitor then dies. Black Sabbath, who is very powerful in the shadows but weak otherwise, almost stabs Giorno, but Koichi intervenes.
Giorno explains his aspiration to Koichi who acknowledges him as the spiritual descendant of the Joestar family.
Having received Koichi's advice as to the nature of Polpo's Stand, Giorno manages to lure Black Sabbath in the open and destroys the stand. The following day, after recieving his membership badge, Giorno kills Polpo.
