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...
If he has no name, he can't be an Archdemon.
إذا كان بلا اسم، فلا يمكن أن يكون
شيطاناً رئيسيّاً
Wenn er keinen Namen hat,
ist es wohl doch kein Erzdämon.
Si no tiene nombre,
no puede ser un Archidemonio.
Si no tiene nombre,
no puede ser un Archdemon.
Il y a donc des chances
que ce ne soit pas un Archidémon.
Se non ha un nome
Se não tem nome,
não pode ser um Arquidemônio.
Раз безымянный…
значит, до архидемона не дорос.
