Aozora Soft acquired for a high price the shocking footage of a janitor working at a public school in the Kanto region who secretly filmed underage girls urinating over an extended period. The filming was conducted using four high-performance miniature cameras, capturing high-quality footage from angles favored by enthusiasts, including close-ups of faces, crotches, and anuses. Numerous hairless girls appear in the video, filmed wearing various outfits such as school uniforms, track uniforms, gym uniforms, and tennis wear. The recordings were likely made in a restroom located behind a school gymnasium.
