At the age of 12, Angelo was convicted for robbery and rape, and since then spent 20 years of his live in prison. He becomes known as one of the biggest criminals in Japan, having been guilty of the rape and murder of three boys, on March 1994. At the time, he was finally arrested by Ryohei Higashikata, and obtained his stand in prison using the Bow and Arrow, presumably from Keicho Nijimura. He was hung in October, but was unable to die and escapes two weeks later after the failed execution. Once out of prison, Angelo goes on killing spree, getting people to drink his watery stand before using it to cause their heads to be torn apart from within, as well as possessing people's bodies to commit crimes.
