While visiting a store in Landosol, Yuuki and Kokkoro encounter Aoi wearing an unfamiliar uniform. It turns out that Aoi is a new student at the prestigious St. Theresa's Academy for Girls, but is worried she won't be able to fit in. Thus Yuuki and Kokkoro head to the school with her as moral support.
As long as we have Rosetta, 
we won't get lost.
.ما دامت روزيتّا معنا، فلن نضيع
Solange Rosetta bei uns ist,
verlaufen wir uns nicht.
Mientras tengamos a Rosetta,
no nos perderemos.
Mientras tengamos a Rosetta,
no nos perderemos.
Avec Rosetta,
impossible de se perdre.
Con Rosetta al nostro fianco
non ci perderemo mai.
Não nos perderemos
enquanto tivermos a Rosetta.
Пока Розетта с нами, мы не потеряемся.
