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...
But if we are completely cut off,
،لكن إذا عُزِلنا بشكل كامل
Allerdings könnte eine Abriegelung
Tuttavia, se ci isoliamo del tutto,
Mas ficaríamos completamente isolados,
Правда, полная изоляция...
