Oomuro Sakurako is in her first year of middle school, and she's always cheerful and energetic, whether she's at home or at school. She has fun every day, and is constantly exasperating her older sister Nadeshiko and younger sister Hanako. Today she had Himawari help her with her homework at school, so she came home in a great mood. But the house was quiet and nobody seemed to be home. Actually, though, Hanako had gotten home before her and was hiding behind the couch. There was a reason that Hanako didn't want Sakurako to find her, but Sakurako finds her easily and bursts out laughing. Hanako had a beard drawn on her face with marker. Hanako gets mad at how hard Sakurako is laughing, but her big sister Nadeshiko gets even madder. The ice cream she was looking forward to eating has gone missing! Hanako and Nadeshiko both suspect Sakurako of eating the ice cream, and Sakurako finds herself outnumbered.
With three sisters, it often comes down to two against one.
