Rimuru backs Clayman into a corner trying to get him to reveal who he's working for, but even on death's door, Clayman's lips are sealed. Left with no other choice, Rimuru finishes Clayman off. With Clayman dead and Carrion and Frey announcing that they're stepping down as Demon Lords, the total number of Demon Lords including Rimuru is reduced from ten to eight. Guy coerces Rimuru into coming up with a new name for their group, and Rimuru's solution is "Octagram," representing each of the Demon Lords as an eight-pointed star. Thus a slime became one of the eight Demon Lords, marking the start of a new age.
Rimuru, you stand before us 
today as a new Demon Lord.
ريمورو، أنت تقف أمامنا اليوم كسيّد شيطان جديد
Rimuru, der du heute als
neuer Dämonenkönig vor uns stehst!
Rimuru, hoy te recibimos
como Rey Demonio
Rimuru, hoy te recibimos
como Rey Demonio
Limule, à l’occasion de ton élévation
au rang de roi-démon,
Limur, nostro nuovo Re demone...
Rimuru, hoje você está diante de nós
como um novo Lorde Demônio.
О Римуру, вознёсшийся сегодня
до титула Князя Тьмы!
