To put a stop to Clayman's plans, Rimuru uses transport magic on a large scale to both move Tempest's army to Eurazania and evacuate the people of Eurazania to Tempest. Rimuru also decides to crash Walpurgis, the Demon Lords' banquet, in order to settle the score with Clayman personally. Since this will be a return match for Shion, he decides to take her and Ranga along. New military forces are organized in Tempest in preparation for the battle against Clayman's army. At last, the eve of battle is upon them...
Still, I wonder why 
Lady Milim has not returned...
...رغم ذلك، أتساءل لماذا لم تعد ميليم-ساما بعد
Aber ich frage mich, warum
Meisterin Milim nicht zurückkehrt.
Me pregunto
por qué no regresa la señora Milim.
Me pregunto
por qué no vuelve la señora Milim.
J’aimerais bien savoir pourquoi
dame Millim ne revient pas.
Però... mi chiedo come mai 
la Grande Milim non faccia ritorno...
No entanto, por que a
Milim-sama não retornou?
И всё же… интересно,
почему Княжна не вернулась?
