Buster is a Bulldog carrying the Knight mark, the sort of pup other pups quietly wait to introduce themselves to. There is a small notebook Buster carries, half theories about the overgrown stadium rim and half crumbs. Around the rooftop kennels, Buster is treated like a small weather system that mostly improves the day. Some pups think Buster is a small answer to the old question of whether the Pixel Pups were made to replace, save, or remember humanity. Legendary detail: When the campfire talk turns serious, pups mention Buster alongside the line the archive once spoke into the Continuity Wing, primary four subjects detected, because Knight is not treated as decoration in The Yard.
