Rimuru is building a dungeon in preparation for the upcoming festival. It will feature treasure chests containing weapons made by Kurobe, and Veldora will inhabit the deepest floor as the final boss. Then Milim suddenly shows up with a suggestion...
can never die within a dungeon 
that she's created.
لن يموت أبداً ضمن ديماس صنعَتْه هي
werden in Dungeons,
die sie geschaffen hat, unsterblich.
se vuelven inmortales en su mazmorra.
se vuelven inmortales en su mazmorra.
les subordonnés de Lamilis
sont immortels.
nunca morre dentro de
uma masmorra que ela criou.
становится бессмертен
в пределах её подземелья.
