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.
For 400 years, I have loved only one woman.
لأربعمئة عام، لم أحبّ سوى امرأة واحدة
Vierhundert Jahre lang habe
ich nur eine Frau geliebt.
Llevo 400 años amando a una mujer.
Llevo 400 años amando a una mujer.
Pendant quatre siècles, je n’ai aimé
qu’une seule et même femme.
Per 400 anni io ho amato una donna soltanto.
Por 400 anos, eu continuo
amando uma única mulher.
Уже четыреста лет меня 
не покидает любовь к одной девушке.
