An amateur girl comes to Tokyo for her first AV shoot, displaying a surprisingly innocent and naive demeanor, knowing almost nothing about what AVs actually entail. Despite having no prior exposure to the AV world, she unexpectedly shows signs of being an aggressive girl, immediately participating in a threesome and grabbing two penises with her hands. She is then thrown into a classroom called "Male Actor Training," where men gather, without being told any details. With growing tension, she instinctively begins to move her body. When she's in her uniform and subjected to anal play, her reactions are fresh and adorable, displaying an expression full of first-time experiences.
