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...
Knowing will only bring you despair...
...فالمعرفة لن تسبّب لك سوى اليأس
Selbst wenn du es wüsstest,
du müsstest doch nur verzweifeln.
Saberlo solo te hará desesperar.
Saberlo solo te desesperará.
Tiens-tu donc
à sombrer dans le désespoir ?
Saperlo non ti porterà altro che disperazione!
Sabê-lo só traria desespero.
Ведь ответ подарит тебе лишь отчаяние!
