Himeno has a young cousin named Shino-chan. Manami, as well, has three young triplet sisters, and an even younger fourth sister. One day, Manami orders her triplet sisters to stay home and watch their youngest sister while she goes out. This leads the four youngest Mitama sisters to experience a truly mysterious phenomenon...
She's never going to get anywhere 
in the real world like that.
.لن تتقدّم في العالم الحقيقيّ هكذا
Wenn sie so bleibt,
Nunca irá a ningún lado
en el mundo real siendo así.
Nunca irá a ningún lado
en el mundo real si es así.
Elle devra bien s’adapter,
en entrant dans la vie active.
In questo modo, non arriverà mai
da nessuna parte nel mondo degli adulti.
Ela nunca vai chegar a lugar nenhum
no mundo real assim.
Так она ничего не добьётся 
в реальной жизни.
