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...
Try anything funny, and you can expect 
to be seen as a demon and cut down.
أي حركة طائشة من أي شخص سنعتبر
صاحبها شيطاناً ونقتله
Seid euch bewusst, dass euch mein Schwert
richten wird, solltet ihr das nicht tun.
Si hacen algo extraño, los veremos
como demonios y los mataremos.
Si hacéis algo extraño, os
consideraremos demonios y os mataremos.
À la moindre bizarrerie,
je vous considérerai comme l’un d’eux !
Se fate qualcosa di strano
Quem vier com gracinhas será
considerado demônio e será morto.
Кто решит чудить —
