A pure yet perverse desire to "see glowing urine" gave birth to this work. The filming begins by having the actresses drink nutritional drinks and turning off the lights. In a darkened studio illuminated only by blacklight, the performers initially chuckle nervously, but their excitement quickly rises as they begin to urinate. Reactions like "It's like a festival!" "I've never seen this before!" "It looks so different!" "It's beautiful, even though it's dirty!" reveal their fascination and delight at the sight of their glowing streams. This experience makes it clear that even excrement, usually avoided, becomes intriguing when it appears "beautiful." The four themes—[Maximum Urination], [Accidental Urination], [Bladder Observation], and [Underwater Urination]—are presented in the "Twilight Version," where the stark contrast between darkness and light creates an immoral, erotic atmosphere. In [Twilight Self-Recorded Maximum Urination], a close-up genital camera clearly captures the glowing urine stream, while a measuring cup filled with 650cc of urine shines brilliantly, evoking awe. In [Twilight Accidental Urination], infrared cameras capture women struggling to hold their urine in the dark; when blacklight is shined on the wet stains left on their denim, it creates a retro cinematic vibe. [Twilight Bladder Observation] features a unique, moody aesthetic as a gutter box beneath them grows brighter with each passing stream, while urine volume and abdominal circumference are carefully measured, emphasizing the observational aspect. In [Twilight Underwater Urination], urine released through swimsuits spreads luminously throughout the bathtub, creating a mystical visual effect resembling CGI or theatrical stage lighting, highlighting its striking visual appeal. Produced by Haishetsuya, the main feature includes visible faces.
