False Jogasaki is an in-universe impersonator within the shared narrative universe. This figure appears during a guerilla theatre performance at a school festival, adopting the identity of the established character Jogasaki for theatrical purposes. The impersonation serves a narrative role in the film's depiction of surreal events unfolding over a single night. The character emerges within the school festival storyline as a performer who assumes this persona. As an impersonator, False Jogasaki contributes to the layered reality experienced throughout the night's adventures. This representation explicitly distinguishes itself from the original Jogasaki character through its framing as a deliberate theatrical construct.
