Synopsis: Gomen Asobase!

Included in the Yuu Watase Masterpiece Collection Volume 1 are four captivating tales. The first story, "Gomen Asobase!", depicts Miyagawa Hao's move from Osaka to Tokyo. While battling a headache, a suave stranger offers Miyagawa a presumed pill, but instead, she receives an essential button belonging to the mysterious man. Surprisingly, she discovers that the button's owner attends the same school, where boys and girls are divided by a wall. The succeeding two stories, "Pajama de Ojama" and "Pajama de Labyrinth," center on Misaki Aguri's endeavor to be transported to her crush, Isozaki, by wearing matching pajamas. However, her plan falters, and Misaki is instead taken to unexpected destinations. Lastly, "Koori Musume wa Otoshigoro" shares the story of Kahyouzan Koori and her affection for Kazama Shuuhen. Regrettably, Koori's grandmother disapproves of their relationship and presents the pair with a test. If Koori can cut the string tied around their fingers, Kazama must end his romance with her. Unfortunately for him, the Koori clan has a distinct ability, leaving him with no option but to defend himself.
