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.
It's been a while since
I've gotten a good night's rest.
Ich konnte mich schon lange
nicht mehr ordentlich ausschlafen.
Hacía tiempo que no dormía tan bien.
Hacía tiempo que no dormía tan bien.
J’ai si bien dormi, ça change !
Ne era passato di tempo 
dall'ultima dormita davvero riposante.
Fazia tempo que não
conseguia dormir a noite toda.
Давненько я так хорошо не отдыхал ночью.
