"After being badly wounded by Elsa, Subaru somehow survived and awoke in the mansion of Margrave Mathers, in the Kingdom of Lugunica.

Subaru now lives and works in Roswaal's mansion, working with Ram and Rem, and finally getting Emilia to agree to a date with him. But the day of their promised date never comes as Subaru keeps going back to the day he first awoke in the mansion. He's confused at the thought that he Returned by Death despite having no memory of experiencing anything deadly, but he's determined to repeat his previous actions up to the point of fulfilling his promise with Emilia."
And what happens if you 
lose that thing, anyway?
وماذا لو أضعتِ ذلك الشيء على أي حال؟
Und was passiert überhaupt,
wenn man den verliert?!
¿Y qué pasaba si perdías esto?
¿Y si llegas a perderla?
Qu’est-ce qui se passe, si on le perd ?
On peut le refaire à la mairie ?
E cosa succederebbe se dovessi perderlo?
E se você perder essa coisa, o que acontece?
А что будет, если её потерять?
