When Roswaal happily tells the story of how his romance with Echidna began 400 years ago, Beatrice rebukes him for casually calling it a "romance." Ryuzu interrupts to comment that Echidna saved her, as well. The one thing these three very different people share is their gratitude toward Echidna. But their days spent in both amicable and argumentative conversation about Echidna are brought to an end by one man's arrival.
I will offer myself up for that purpose.
وسأكرّس نفسي لأجل هذا الغرض
Dafür opfere ich mich.
Y entregaré mi vida para eso.
Y entregaré mi vida por ello.
C’est dans ce but
que je donne ma vie.
E io intendo offrirmi per renderlo possibile.
Eu oferecerei o meu corpo
para este propósito.
И ради этого 
я готова пожертвовать собой.
