While the main cast forms the cozy heart of Liminalism, each episode introduces fleeting oddities, eccentric neighbors, and whimsical one-off characters that bring the fractured world to life.

These “extras” might include:

• Background voices: quirky shopkeepers, chatty café patrons, or the cashier with wings who sighs every time Den forgets his wallet.

• One-off surreal characters: a mailbox that argues about proper postage, a sentient soda machine with an opinion on everything, or a hallway that insists on giving directions.

• Recurring side voices: neighbors, classmates, or everyday people who appear normal—until the liminal chaos slips in.

The tone of these extras is lighthearted and playful, adding texture to the world without overwhelming the main cast. Their personalities often lean slightly “offbeat”—comfortably odd, never threatening—mirroring the dreamlike coziness of the series.
