Johngalli A.

Jongalli A is a minor antagonist from Part VI: Stone Ocean.

About
Jongali is an ex-soldier sentenced to 7 years in prison for murder. As a follower of Dio, he wants to take revenge on the Joestar bloodline by framing Jolyne Kujo and hoping to kill her in prison. Even though he's blind, he is capable of perceiving his surroundings by an inhuman ability of feeling wind movement, presumably from owning a stand. He's able to keep a sniper rifle with him even in prison by disguising it as a cane.
