The line comes from The World Ends With You, the Square Enix action RPG first released for Nintendo DS in 2007 in Japan and 2008 internationally. Joshua, full name Yoshiya Kiryu, is a central, enigmatic partner character known for his calm and teasing manner. Short voice clips from the game circulate on soundboards among fans who use them out of context for farewells and story edits. This farewell snippet has stayed in use because it condenses Joshua's distant personality into a single, instantly recognisable goodbye.
