In this monitor project featuring Hazuki Yui, a special setup was arranged to observe psychological states and behaviors when unable to use the toilet—she was required to urinate every two hours. While recounting childhood bedwetting experiences from sixth grade and other incontinence episodes, she suddenly felt a strong urge to pee and stood up, releasing a large stream of urine. After changing her panties and rehydrating, just five minutes later, the fresh pair was already soaked through. Her frequent urination was far from normal. While staff went to buy drinks, she admitted to peeing twice more during camera breaks. When she reached into a diaper soaked with three rounds of urine to check its condition, she suddenly became sexually aroused and began masturbating. This sensation further intensified her urge, triggering another round of urination in a continuous cycle. The diaper eventually overflowed, leaking down the hem and leaving a wet stain on the bedsheet like a bedwetting accident.
