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'm out of magic, 
but Ifrit still has strength.
نفدَ سحري، لكن ما زال إيفريت يمتلك قوّة
Ich habe keine eigene Magie mehr,
No tengo magia,
pero Ifrit aún tiene fuerza.
No tengo magia,
pero Ifrit aún tiene fuerza.
J’ai épuisé ma magie,
Non ho più forza magica,
Estou sem magia, mas ainda
tenho o poder do Ifrit!
Магию я всю истратила…
но у Ифрита ещё силы остались!
