According to a report released by a European research group, a new theory is gaining ground that the G-spot does not exist. Female erogenous zones are now believed to be not limited to a single location like the G-spot, but rather formed by a complex interplay of multiple areas. Introducing this new concept, experts propose the "clitoral-urethral-vaginal complex," or CUV complex, as the key to female pleasure. In this project, Yui Hatano, known across the world as Sekai no Hatano, appears as the test subject to experience the CUV complex firsthand. Having explored countless erogenous zones throughout her career, she now challenges herself to discover an entirely new realm of sensation she's never experienced before.
