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.
My strength alone is insufficient 
to protect our teacher.
قوّتي وحدها غير كافية لحماية معلّمتنا
Ich allein konnte die
Lehrerin nicht beschützen.
No soy lo suficientemente fuerte
para ayudar a la señora.
No soy lo suficientemente fuerte
para ayudar a la señora.
Je ne suis pas assez puissant
pour sauver maître Echidna seul.

a proteggere la nostra maestra.
Minha força é insuficiente
para proteger a professora.
Моих сил недостаточно, 
чтобы защитить наставницу.
