Rimuru learns about Clayman and the schemes of the Kingdom of Falmuth, but no matter how hard he wishes for it, his fallen comrades and their peaceful lifestyle will never return. He's just about to give up when Eren tells him of a fairy tale that might offer a glimmer of hope. The probability of success is about 3%... but if Rimuru can manage to become a Demon Lord by taking in the souls of 10,000 humans as nourishment, he just might have a chance at bringing his comrades back to life. As Falmuth's army of 20,000 men marches toward Tempest, Rimuru takes hold of that hope and decides to become a Demon Lord.
I wanted to get rid of the multi-layer 
barrier that's weakening everyone,
أردتُ التخلّص من الحاجز متعدّد الطبقات
،الذي يضعف الجميع
Ich wollte die Mehrfachbarriere,
die die Schwächung ausgelöst hat, zerstören,
Quería librarme
de la barrera debilitadora,
Quería librarme
de la barrera debilitadora,
Je voulais faire tomber la barrière
affaiblissant les monstres,
Avrei voluto liberarmi 
della barriera a più livelli che indebolisce tutti,
Eu queria eliminar a barreira composta
que causa o enfraquecimento,
Я хотел избавиться от того,
который ослабевает ребят…
