A new school term has started, and parent-teacher meetings are on the horizon. At school, Yuta and Saki still have not told anyone that they are siblings. As their mother, Akiko wants to attend both meetings, but she worries it would expose their secret.
And you'll be my straitlaced little sis, Saki.
وأنتِ ستكونين أختي الصّغيرة الصّالحة ساكي
Saki ist die vernünftige Schwester!
Y tú serás mi hermanita, Saki.
Y tú serás mi hermanita, Saki.
Toi,
tu seras la petite sœur sérieuse.
E tu, Saki, 
sarai la mia intransigente sorella minore.
E você vai ser minha
irmã certinha, Saki.
А Саки — моя надёжная младшая сестра.
