Having worked much too hard, Mile and the others decide the Crimson Vow should cease activities for a little while. In plain terms this means... That's right, every working person's inalienable right —— a vacation! While each of the friends enjoys their time off in their own way, Mile, with her sad history as a master of spending time by herself in her previous life, goes off to savor her time off on her own, but...
Also, on an unrelated note, this episode contains swimsuits.

En ese caso, ¿por qué no decides tú
nuestro destino?

où on ira.
Allora perché non facciamo decidere a Mile dove andare?
Então, vamos deixar a Mile
decidir para onde vamos!
Тогда пускай Миль решает,
куда мы вместе пойдём.
