Byōbu Nozoki originates from Japanese folklore as documented in Toriyama Sekien's "Konjaku Hyakki Shūi". This tsukumogami embodies a folding screen that witnessed frequent sexual activities, manifesting as an impossibly tall humanoid draped in white robes. It peers over screens during intimate acts, sustaining itself on sexual misdeeds with a mischievous yet non-aggressive nature. The character does not appear in the "Shabake" franchise, including its narrative, character roster, novels, manga, ONA, or upcoming TV anime adaptations.
