I actually experienced the VR work featuring Teacher Koharu, and it's hard not to feel the limitations of early VR technology. First off, the miniaturization of the footage is severe, with the entire lower body blacked out, hiding crucial parts completely. Looking down reveals pure darkness, making it feel like an image video. While the actress Koharu is excellent material, the staff's poor camera positioning results in a dark expanse from the waist down, which is truly disappointing.

Moreover, the narrow field of view is problematic, with scenes where only half of the breasts are visible, lacking impact. Despite the absence of a male actor in the setting, there's a slight inclusion of male moaning sounds, which might come off as trolling to fans. Too many scenes with clothes on prevent full enjoyment of the beautiful body, which is a letdown.

That said, Koharu's VR works are rare, and fans might manage with some imagination to fill in the gaps. Given the affordable price, it could be worth buying as a collector's item, but it's safer to wait for higher-quality releases from other manufacturers. I look forward to advancements in VR technology in the future.
