Be in Your First Commercial?

S1, E5: The next step for the Naria girls on their road to idol stardom is to do a TV commercial! But a cunning monster traps them in a hallucination! The monster makes them think that they're a traveling conman trying to pass a married woman off as a high-tech maid robot, and a pure boy who's suspicious, but still can't refuse because he can't stop thinking about the maid's breasts. To get out, they'll have to pretend to be a store employee trying to sell a cucumber, and cast magic spells to get the hair out of a drain!
