Benimaru leads his army to Eurazania, and Youm heads to Falmuth to take it over along with his buddies and Diablo. Rimuru succeeds in outwitting Clayman by transporting all of Eurazania's refugees to Tempest. Since Clayman has been striving to evolve into an Awakened Demon Lord for a long time, his resentment toward Rimuru grows. Meanwhile, Demon Lord Leon, Veldora's sister Velzard, and Guy, the oldest of the Demon Lords, become increasingly impressed with Rimuru.
As you know, the Demon Lords' 
banquet, Walpurgis, is to be held.
كما تعلم، مأدبة أسياد الشّيطان، والبورغيس، ستُعقد
Wie du weißt, wird wieder eine Konferenz
der Dämonenkönige, die Walpurgis, abgehalten.
Como ya sabes,
Como ya sabes,
Comme tu le sais,
Come già sai, si terrà la festa dei Re demoni, il Walpurgis.
Como deve saber, o banquete dos
Lordes Demônios, Walpurgis, será realizado.
Как ты и сам знаешь, со дня на день
начнётся Вальпургиева ночь.
