In a vibrant, absurd world where celestial beings casually drop their halos (and occasionally their egos), players take on the role of a quirky celestial relic picker named Lumo. After discovering an unclaimed halo during a festival, Lumo accidentally triggers a series of comedic misunderstandings with various celestial inhabitants who think they've lost their prized accessories. Players must interact with these beings, solve whimsical puzzles, gather clues, and navigate hilarious confrontations, all while searching for the rightful owner of the halo. The game blends humor with a lighthearted exploration of themes like identity and belonging, leading to zany endings that change based on player choices.
