Hailing from another world, Diego is self-centered and has no apparent capacity for empathy, taking pleas lightly and in a joking manner until he's enticed... if given a task, he is absolutely ruthless, prepared to kill anyone in his way in inventively violent ways such as by throwing knives, in order to complete said task... Diego's Stand, THE WORLD, is a powerful, humanoid Stand capable of stopping time for ~5 seconds.
