The Demon Lord Carrion has sent one of his Three Beastketeers, Phobio, on a raid of Rimuru's city. However, Phobio is quickly defeated when Milim meets his attack with her own. Rimuru and his subordinates then ask Phobio why he has come to their town.
You're fighting monsters 
every time I see you.
أراكم تقاتلون وحوشاً كلّما التقينا
Ihr kämpft irgendwie immer gegen Monster.
Pelean contra monstruos
siempre que los vemos.
Siempre estáis
enfrentándoos a monstruos.
Encore en train
d’affronter un monstre…
Ogni volta che ci incontriamo 
siete nel bel mezzo di una battaglia,
Sempre que te vejo,
está lutando contra monstros.
Вечно вы с магверью воюете…
