The Katamari series’ whole schtick is using a knobbly ball to collect stuff. The King is a toddler, directing your missions, and the Prince is a silent cursor which you use to push a ball in different directions around the world. But Katamari Damacy isn’t a moral lesson or an exploration of that experience, it’s an absurdist roll-’em-up.
The King treats his son terribly, gets out-of-control drunk, and won’t face up to his responsibilities. If you stop to examine the story, it’s pretty bleak. Instead, the sky was ruined by your father partying a little too hard the previous night and now he’s grumpily pressing you into service to fix it. There is no prophesy to fulfil, no monster to thwart.
You, the minuscule Prince of the Cosmos, must help your father, the incredibly buff King of the Cosmos (also unsubtly well-endowed thanks to a pair of spray-on trousers) repair the night sky.
