Sue-chan, the youngest of the Mitama family, has a weak constitution. Manami and her triplet sisters are always worrying about her. On the other hand, Himeno's niece, Shino-chan, isa very curious girl. She asks Himeno all kinds of questions as they go for a walk, and looks adorable doing it. All the little ones—Himeno's niece Shino-chan, as well as Manami's triplet sisters and baby sister Sue-chan—live their own stories.
You make a very good older sister, Shino-chan.
