Seina Yamada has been waiting so long to return to his home, Earth.
But so much has changed; his sister is engaged to Kiriko's brother Kai,
and his parents' old store is now a huge mall.
Furthermore, he is to stay at Kiriko's mother's house...
While the cat's away, or whatever, huh?
في ظلّ غياب القطّ أو أيّاً يكن؟
Wenn die Katze aus dem Haus ist …
Cuando no está el gato…
Cuando no está el gato…
Quand le chat n’est pas là,
les souris dansent.
"Quando il gatto non c'è" eccetera eccetera, giusto?
A diversão acontece quando
os pais saem de casa.
Пока никто не видит, как говорится.
