Rackam comes from Granblue Fantasy, the Japanese role-playing game released by Cygames in 2014 for mobile and browser. In the story he is the helmsman of the Grandcypher and one of the first major allies the captain meets, which made his voice familiar to early players. As the game grew into anime, merchandise and a large fan community, short clips of its cast began circulating on soundboards and in fan edits. Rackam remains popular because his relaxed, dependable personality contrasts with more dramatic characters, making brief lines easy to reuse.
