Rimuru continues with preparations for Walpurgis, including making Treyni evolve into a Dryas Doll Dryad. Meanwhile, Benimaru and his forces have arrived in Eurazania via transport magic, and they promptly run Clayman's army into a trap set by Geld. The Three Beastketeers, determined to rescue Carrion, set out to subdue the enemy army's leader. Albis fights one-on-one with Yamza of the Five Fingers, while Phobio takes on Footman and Tear.
Sir Phobio, the guy who failed 
to become a Demon Lord!
!فوبيو-ساما، الشّخص الّذي فشل أن يصبح سيّد شيطان
Meister Phobio,
der Dämonenkönig werden wollte.
Le sire Phobio
qui a manqué devenir roi-démon !
È proprio il Grande Phobio, 
quello che non è riuscito a diventare Re demone!
O Phobio-sama, que não conseguiu
ser Lorde Demônio!
Лорд Фобио,
не сумевший стать Князем Тьмы!
