Shion and the rest of the fallen are revived, Diablo has joined the team... It seems as if all is going smoothly, but Rimuru then receives a report that Milim has declared war and Eurazania has been destroyed, and there's still the matter of the Western Holy Church's hostility toward monsters, even with Falmuth out of the picture. But at the same time, Raphael informs him that the Appraisal of Unlimited Imprisonment has been completed. At last, two years after Rimuru's reincarnation into this world, he can finally fulfill the first promise he made here: to free Veldora.
I wanted to defeat you in your best 
condition and prove that I'm the strongest!
أردتُ هزيمتكِ بأحسن حالاتكِ
!وأثبت أنّني الأقوى
Ich wollte dich besiegen, während
Quería derrotarte en plenas facultades
y demostrar que soy el más fuerte.
Quería derrotarte en plenas facultades
y demostrar que soy el más fuerte.
Je voulais prouver ma supériorité
en te battant au faîte de ta puissance !
Avrei voluto sconfiggere la vera Milim
Pois eu queria te vencer
Мне-то хотелось победить тебя истинную,
чтобы доказать, что я сильнейший!
