One hot summer day, the 4 girls and Haruko are playing in the pool. They notice that Pets is missing. Kana later hears from her classmate Aida that Pet's family is very rich and they are moving to Mars. 
Kana-bun... We'll always
be together from now on.
Kanalein, bleiben wir für immer zusammen.
Kanabun, estaremos juntas por siempre.
Kanabun, estaremos juntas siempre.
Kanabun,
on ne se quittera jamais.
Kana-bun... d'ora in poi, saremo sempre insieme.
Kana-bun... A partir de agora,
vamos estar sempre juntas.
Канушка... Мы теперь
всегда будем вместе.
