"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."
Okay, if you can do it after I keep my 
promise to Emilia-tan, that'd be great.
سيكونُ من دواعي سروري أن يتمّ
هذا بعد وفائي بوعدي لإيميليا-تان
Nachdem ich mein Versprechen mit
Emilia-tan erfüllt habe, bitte ich darum.
Sería bueno hacerlo
luego de cumplir mi promesa con Emi.
Estaría bien hacerlo
luego de cumplir mi promesa con Emi.
Je compterai sur toi
si je tiens ma promesse à Émi.
Allora, facciamo dopo che avrò tenuto fede 
alla promessa con Emiliuccia.
Então, vamos esperar eu cumprir 
minha promessa com a Emilia-tan.
Хорошо. Подстрижёшь, когда
 исполню обещание, данное Эмилии-тан.
