"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."
Don't underestimate how vindictive I'll be
،لا تستهِن بانتقامي غداً
Er weiß nicht, wie nachtragend ich sein kann,
nachdem ich dieses Lächeln gesehen hab.
No subestimen lo vengativo que seré
tras la sonrisa que de esa noche.
No subestiméis lo vengativo que seré
tras la sonrisa que de esa noche.
Je suis devenu fou de ce sourire.
Vaut mieux pas me sous-estimer.
Da quando il suo sorriso mi ha stregato, quella notte,
sono diventato molto vendicativo, state attenti.
Não subestimem o quão vingativo eu posso ser,
Жди мою страшную месть за то, 
что украл ту очаровательную улыбку!
