CCD Planning's "Rough Angler" presents a new release: "Underground World! Back Then, We Used to Do These Risky Things Casually 02." This work contains leaked footage from an underground event hosted by a certain entertainment agency, realistically recreating the bizarre events of the past. At that time, regulations were lax, and it was normal for audience members to climb onto the stage and grope performers freely. The video captures wild scenes of performers with vibrators shoved into their panties, audience members rushing in to apply the vibrator directly, and repeated accidents. The crowd goes into a frenzy, creating a truly massive underground event atmosphere. The performers themselves contribute to the chaos, with some girls getting completely drunk and stripping naked. Perverts gather as well, and much of the content borders on criminal acts. The situation spirals completely out of control, including extreme scenes where breasts are touched freely. This is rare footage preserving the atmosphere of a now-defunct agency.
