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.
And I just can't condone what Falmuth 
and the Western Holy Church are doing!
ولا أؤيّد ما تفعله فالموث والكنيسة
الغربيّة المُقدّسة
Und ich kann dem Königreich Farmas und
der Westlichen Heiligen Kirche nicht vergeben!
Además, el reino de Falmuth y la
Iglesia Occidental son imperdonables.
Además, el reino de Falmuth y la

Et puis, les méthodes de Farmus
et de l’Église de l’Ouest m’écœurent !
E non posso perdonare i metodi 
del Sacro concilio dell'ovest e del Regno di Falmuth!
Além disso, as ações do Reino de Falmuth e da
Igreja Sagrada Ocidental são imperdoáveis!
А то, что натворили королевство Фалмус
 и Церковь, вообще непростительно!
