Through three distinct scenarios, she narrates her experiences as the tentacles consume her body, delving deep into the legend of how women of that era became possessed by this ecstasy, losing their reason and surrendering to primal physical instincts. The theory that the thick, milky fluid secreted by the tentacles stirs a woman's mind and drives her toward overwhelming pleasure remains an enigma to this day. Witness how Aoi Hazuki, the big-breasted navigator, reacts to the seductive power of these tentacles—her transformation revealed here and now.
