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...
It seems the time has finally 
come to unleash my aura!
يبدو أنّ الوقت قد حان أخيراً
!لإطلاق عنان هالتي
Endlich ist es so weit!
¡Ha llegado la hora de liberar mi aura!
¡Ha llegado la hora de liberar mi aura!
Enfin ! Je suis libre de relâcher
mon aura à ma guise !
Parece que finalmente chegou
a hora de liberar minha aura!
Наконец-то этот час настал!
Пора высвободить мою ауру!
