Giovanni

Giovanni is an illegal weapons dealer from Poko City, Simo Island. He owns a hidden basement restaurant/bar in a midcity alley, and visitors must be members of the bar to get in. He lives in one of the back rooms of the bar, functioning as a bedroom. He is of main concern in the beginning of the End of Earth arc, at which time Chris was given a mission to find and kill a man named Giovanni somewhere in north-eastern Simo, as he would be making a transaction with Token soon, wherein Lab Co. would acquire nuclear weapons.

After going to Poko City, gambling and growing increasingly frustrated with being unable to find Giovanni, Chris and Falgo get a tip of his location from a seedy gambler for winning a bet in blackjack. After locating him, Falgo spars with Giovanni, killing the latter in battle.

Heaven No More arc
During the Heaven No More arc, Falgo is ambushed in the Paki Islands by a large group of thugs that are determined to avenge Giovanni, leaving Falgo maliciously wounded.
