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...
That should suffice as a reason 
to not allow any outsiders in, right?
ينبغي لهذا أن يكفي كسبب لعدم
السّماح لأيّ غريب بالدخول، صحيح؟
Das genügt als Grund,
niemanden reinzulassen.
Es motivo suficiente
para no dejar entrar a nadie.
Es motivo suficiente
para no dejar entrar a nadie.
c’est une raison suffisante

Deve ser suficiente como motivo para não
permitir que forasteiros entrem, não acha?
Это ведь адекватная причина
никого не пускать?
