Rimuru succeeds in collecting enough souls to carry out his plan to evolve, and the Harvest Festival begins. But he's suddenly overcome by intense sleepiness at the same time, so he summons a demon to stop Razen, the one target who escaped alive. Then, upon returning to Tempest after successfully becoming a Demon Lord, Rimuru sets about attempting to revive Shion and the rest of the fallen. Through Raphael, the evolved form of Great Sage, the Secret Arts of Spirit Resurrection and Revival of the Dead are activated...
Isn't magic a demon's greatest weapon?!
!أليس السّحر هو السّلاح الأعظم للشيطان؟
Für Dämonen ist ihre Magie
doch die stärkste Waffe!
La magia es la mayor fuerza
de los demonios.
La magia es la mayor fuerza
de los demonios.
C’est la plus grande arme
de ton espèce !
Per un diavolo, la magia è l'arma più forte.
Para um demônio, sua maior arma
deveria ser a magia!
Это ведь ваше же, демонов, 
главное оружие!
