The Visitor (3) (面会人 その③ Menkainin Sono 3), originally Johngalli A the Sniper (狙撃手ジョンガリ・A Sogeki Shu Jongari A) in the WSJ release, is the six hundred seventh chapter of the JoJo's Bizarre Adventure manga. It is also the thirteenth chapter of Stone Ocean.
The pressure from the bullet sends Jolyne flying back into a table. Jotaro warns her to stay away from the door, as the sniper has been waiting for his chance to kill them. Jotaro commands his daughter to put out the cigarette, which she does reluctantly. Believeing the sniper is using a Stand to somehow sense their movement and location, he explains how Johngalli A could sneak in a silenced sniper rifle and used his Stand to send the bullet into the visiting room.
Jolyne looks at the bone Emporio gave her, and remembers his warning to her. Jotaro tells her that its a female's pelvis bone melted down with acid. He then looks outside to see Johngalli A's Stand, Manhattan Transfer, gliding outside the room. The Stand appears to dance around in the air. Jotaro warns his daughter not to do anything, but she tries to launch a string at it. It dodges, causing Jolyne to realize that it reacts to air currents.
As they watch the Stand, the prison guard Jolyne had knocked out wakes up and tries to attack her. She tries to warn the guard of the danger, but the guard is too enraged to listen. Jotaro summons Star Platinum to stop time and knock away the guard, but is too late as Johngalli's bullet pierces his shoulder; the bullet rips through Jotaro and hits the guard directly in the head. Jotaro figures out how Manhattan Transfer is used—a sniping satellite that senses the location of his opponents and redirects his bullets.
