Meguru is in a deep depression over how the battle with Nui and Veil ended, and Mary does all she can to deepen the wound. When Meguru goes missing, Sumire does all she can to find her. Eventually, Nagatsuki and Miruku take her to meet the heads of the Kannazuki household...
So if they have Meguru, then even 
without collecting any new medals...
،إن كانت ميغورو بحوزتهم
...فحتّى دون جمع ميداليّات جديدة
Dann brauchen sie mit Meguru gar keine
neuen Medaillen mehr sammeln …
Entonces, si tienen a Meguru,
no necesitan reunir más.
Entonces, si tienen a Meguru,
no necesitan reunir más.
Donc ils n’ont plus besoin
d’amasser des médaillons ?
Quindi, ora che il nemico ha catturato Meguru,
non ha più bisogno di raccoglierne di nuove.
Então com a Meguru, mesmo que não
peguem mais nenhuma medalha...
Значит, если у них Мегуру, 
то им даже незачем собирать новые медальоны?
