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...
And the declaration of war was just 
some Otherworlders going on a rampage!
وأمّا إعلان الحرب فقد كان مجرّد هيَجان
!من الأُخرويّين وخروجهم عن السّيطرة
Diese Andersweltler haben
eigenmächtig den Krieg erklärt.
La declaración de guerra fue
cosa de los de otro mundo.
La declaración de guerra fue
cosa de los de otro mundo.
Les seuls responsables de ce quiproquo
sont les transfuges !
La dichiarazione di guerra 
è opera di quegli stranieri fuori controllo!
E a declaração de guerra
Мы не объявляли войну…
это просто иномирцы посходили с ума!
