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.
So I think it'd be a good idea for me 
to know about the other Demon Lords.
لذا أعتقد أنّ معرفتي بأسياد الشيطان الآخرين
ستكون فكرة جيّدة
Deshalb sollte ich doch auch was
über die anderen Dämonenkönige wissen.
Creo que sería buena idea
que sepa de los otros Reyes Demonio.
Creo que sería buena idea que
me hablases de los otros Reyes Demonio.
Il suffirait juste que j’en sache
un peu plus sur les autres rois-démons…
Quindi
Então acho melhor eu ter uma ideia
de como são os outros Lordes Demônios!
Потому я и думаю, что мне стоит
и про других Князей тоже знать!
