"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."
I only collected the mana 
from your body, I suppose.
لقد استخرجتُ المانا من جسدِك فحسب على ما أفترض
Ich habe nur das Mana
aus deinem Körper entzogen.
Solo reuní el maná de tu cuerpo.
Solo he reunido el maná de tu cuerpo.
J’ai juste prélevé
une petite dose de ton mana,
Ho solo estratto il mana dal tuo corpo, oserei dire.
Eu só coletei a mana do seu corpo, imagino.
Всего лишь позаимствовала твою ману.
