Subaru laments that he could not do anything or save anyone, and has no options left. Exhausted, he suddenly takes off running at full speed as if he's made a decision... To save Emilia, Subaru approaches Crusch to negotiate the formation of an alliance. His terms are a bit difficult for Crusch to believe, but she can see that Subaru isn't lying.

¿Vosotros sois hermanos?
Quindi siete fratello e sorella, eh?
Então vocês dois são irmãos?
Вы, получается, брат и сестра?
