Yuuto's been sent to another world, where he is now commander, or "Patriarch" of a clan of warriors.  To survive in this new world, he uses his cell phone, his only connection to the girl he loves back home.
I can tell I'm still on Earth because
the stars are exactly the same here.
Dass ich noch auf der Erde bin, weiß ich,
weil die Sterne hier exakt dieselben sind.
Lo sé porque las estrellas
están igual que antes.
Lo sé porque las estrellas
están igual que antes.
Si je dis ça,
Posso affermare di essere sulla Terra 
perché ci sono esattamente le stesse stelle.
Posso dizer isso porque as estrelas
continuam como eram.
Я уверен, что я всё ещё на Земле, 
потому что звёзды здесь точно такие же.
