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...
Maybe your sisters could put up 
with you being late for once?
ربّما يمكن لأخواتك الصغار
أن يتحملن تأخرك لمرّة؟
Deine kleinen Schwestern
könnten doch auch mal warten …
Tal vez tus hermanas estén bien
si llegas tarde una vez.
Tal vez tus hermanas estén bien
si llegas tarde una vez.
Je pense que de temps en temps,
tu pourrais laisser ta famille…
Magari le tue sorelle possono sopportare
un tuo ritardo, per una volta?
Talvez suas irmãs possam aguentar
que você se atrase uma vez?
Может, твои сёстры смогли бы один раз 
подождать тебя чуть дольше?
