Junpei Iori is one of the main party members in Persona 3, a role-playing game by Atlus, and he returns in the remake Persona 3 Reload. His loud, optimistic personality made him a fan favourite, and short voice lines like this one are often clipped by players for edits, reaction videos and gaming memes. Because the line is short, clear and instantly upbeat, it travels well outside the game itself, working as a universal signal that something exciting is about to begin.
