The half of the mercenary army that had been blocking the road during the White Whale subjugation returns to join the main force. Subaru then leads the way into the forest of the Mathers domain, hoping to find and destroy the Witch's Cult before they can learn of the subjugating army's movements. 
Subaru and his companions head toward Roswaal's mansion to evacuate Emilia and all the others there, stopping at the nearby village on the way and beginning to evacuate its residents as well. However, the situation takes a turn that nobody expected...
There will be chaos if we don't
Wenn wir Emilia und den anderen
Sería un caos si Emilia y los demás
no se enteraran sobre la alianza.
Sería un caos si Emilia y los demás
no se enterasen de lo de la alianza.
Il fallait les mettre au parfum
pour éviter la confusion.
Ci sarà il caos
Com certeza haveria caos
Если не предупредить Эмилию 
и остальных о союзе, начнётся хаос.
