Before diving into the UPD (update), let’s establish the premise. The series—often shortened to NEAF by fans—centers on Raphy, a fallen angel who has been kicked out of heaven for one specific sin: sloth. Rather than conquering the mortal realm or seeking redemption, Raphy opts to live as a shut-in in a dilapidated Tokyo apartment.

Her life changes when she is discovered by the Tachibana Family, a household with a very peculiar reputation in their neighborhood. Dubbed the "Ero Family" (a play on "Ero" meaning erotic/lewd, but also a corruption of their surname), the Tachibanas are not perverts—rather, they are cursed. Every family member, from the stoic older brother Kenta to the bubbly younger sister Moe, accidentally creates sexually charged situations whenever they try to perform mundane acts of kindness.

The story follows Raphy trying to mooch off the family while the "Ero Curse" constantly derails her lazy paradise.
