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.
As a matter of dignity, we shall 
have to come up with a new name.
لأجل الوقار، سيتوجّب علينا البحث عن اسم جديد
Um unsere Würde zu bewahren,
On va devoir se trouver un nouveau nom,
question de prestige.
Dovremo pensare ad un nuovo nome, 
è una questione di dignità.
Por uma questão de dignidade,
teremos que pensar em um novo nome.
Теперь, по-хорошему,
 мы должны придумать себе новое название.
