Now that they each know the burdens of each other's pasts, the Crimson Vow has only grown closer. Their job guarding has come to a successful close and they have a moment to enjoy a brief rest, but sudden bad news brings the smoldering embers of Reina's resentment roaring back to life. How will Mile and the others face this first threat to the Crimson Vow? Their friendship is about to be tested...
We four, the Crimson Vow, 
will return to the capital together!
نحن الأربعة، العهد القرمزي، سنعود إلى العاصمة معاً
Wir, der Blutrote Eid, werden nämlich
vollzählig zur Hauptstadt zurückkehren!
Las cuatro, el Voto Carmesí,
¡volveremos juntas a la capital!
