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's a terrifying thing 
to say so casually...
...هذا كلام فظيع يُقال بشكل عفوي
Dass dir das so leicht
über die Lippen geht …
Tu m’enfonces sans état d’âme, là…
Certo che dire una cosa tanto terrificante 
come nulla fosse...
É terrível falar isso do nada.
Не говори это так спокойно.
