This story takes place before Rimuru's reincarnation. Shizu, also known as the Conqueror of Flames, responds to an urgent request calling her to the Kingdom of Filtwood. When she reaches the castle, many adventurers are already there. What request could have demanded such a huge gathering? It turns out a demon has been revived, and the adventurers have been called to subjugate it. It is said that more than ten of the most skilled adventurers have already been killed by this demon. But there is more to this request than meets the eye...
I've simply determined that there's no 
reason I should be the only one rebuked.
ارتأيتُ ببساطةٍ أنّه لا يوجد سببٌ يدفعني
لأكون الشّخص المُؤنَّب الوحيد
Ich kam also zu dem Schluss,
sodass ich nicht alleine Schuld sein würde.
Solo decidí que no hay razón
para ser el único ignorado.
Solo he decidido que no hay razón
para ser el único ignorado.
je ne vois aucune raison
de m’y opposer.
Sono solo arrivato alla conclusione 
che non c'è ragione per cui devo essere sospettato.
Apenas entendi que não há razão para que
eu seja o único a ser repreendido.
Следовательно, никто не станет
порицать лишь меня.
