"Please let me use your toilet." A mysterious girl named Shizu appears before Uta, who is drying out her bedwetting futon. Uta is confused, but Shizu, unable to hold back, fidgets and has an ecstatic expression. Shizu has peed right in front of Uta. Uta worries, and Shizu responds. "I'm sorry, the toilet, it's okay now... I peed..." Shizu lifts her skirt and there is a cutely patterned diaper... After this chance encounter, Uta and Shizu suddenly become close. The two share each other's secrets... The story begins with an ordinary everyday life, but it is filled with the confusion of an adolescent girl. Her struggles with pee. Her misunderstandings with her father. Her first kiss. Her first diaper. A smelly bedwetting futon. The warmth of her older sister. The bittersweet love between the two intertwines in various ways, leading to an unexpected conclusion... Machino Hikaru, a genius of diaper dramas, took the helm for the first time in about 10 years, and using 4K equipment to film, he carefully captured not only the diaper patterns, but also the clear flow of urine and the delicate skin texture of adolescent girls. Please enjoy this adolescent diaper drama revived in the Reiwa era. As a video bonus, it also includes a collection of NGs and behind-the-scenes footage of Uta Hibiki Nana Ao Noa.
