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.
Along with the new moon, 
Walpurgis Night will begin.
مع اختفاء القمر، سوف تبدأ ليلة والبورغيس
Die Nacht des Neumonds,
Walpurgis, nähert sich.
Se acerca el día del Walpurgis
y la luna nueva.
Se acerca el día del Walpurgis
y la luna nueva.
La nuit du Walpurgis
se tiendra à la nouvelle lune.
A breve ci sarà la luna nuova, 
e con essa il Walpurgis.
Com a lua nova, a Noite
de Walpurgis começará.
На полнолуние…
начнётся Вальпургиева ночь.
