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.
But I still think our big 
sister is prettier.
ولكن لا أزال أعتقد أنّ
.أختنا الكبيرة أجمل
Pero creo que nuestra hermana
es más bonita.
Pero creo que nuestra hermana
es más guapa.
Mais notre grande sœur
est encore plus belle.
Ma la nostra sorellona è ancora più bella di te.
Mas ainda acho que nossa
irmã é mais bonita.
Но всё равно наша старшая сестра 
красивее.
