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.
But the truth is, only a few people 
in Thalion know that fairy tale.
لكن الحقيقة هي أنّ قلّة من الناس
في ساريون يعرفون تلك الأسطورة
Aber wissen Sie? Dieses Märchen
kennen nicht viele in Sarion.
Pero ese cuento
no lo conoce mucha gente.
Pero esa historia
no la conoce mucha gente.
Mais vous savez, même à Salion,
peu de gens connaissent ce conte.
Ma a dire il vero,
Mas aquele conto de fadas é conhecido
só por poucas pessoas de Sarion.
Только вот… эту легенду даже в Сарионе
знают очень и очень немногие.
