Arata, once and for all, tries to make the dense-as-can-be Kazuomi realize what he has in his hands.
It's a precious time that won't come again.
.إنّه وقتٌ ثمين لن يرجع أبدًا
Eine wertvolle Zeit,
die nicht wiederkehren wird.
É uma época preciosa
 que não volta mais.
Драгоценное время,
больше не повторится.
