Tachibana accidentally received an invitation to participate in an adult film in which she would play the lead role, from a famous director. After eagerly getting ready and quickly arriving at the meeting place to discuss the job, she found herself in a deserted and remote hotel on the outskirts. As soon as she entered the room, she was unexpectedly restrained and then continuously assaulted by two tall, bare-chested men. In that moment, she deduced the entire situation: the director had arranged this incident to see how she would react in order to capture the most authentic scenes. In the end, her response did not disappoint him; not only did she quickly adapt to the threesome, but she also performed her role very well in this adult film.
