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.
it is because of you that we have 
fewer Demon Lords now.
بسببك قلّ عدد أسياد الشّيطان لدينا الآن
der die Anzahl der Dämonenkönige gesenkt hat.
Wegen dir haben wir das Problem erst.
c’est à cause de toi
qu’on a perdu des membres.
sei la causa che ci ha portato
a perdere diversi Re demoni.
é por sua causa que temos
menos Lordes Demônios agora.
что это ты подрезал число Князей,
и нам теперь приходится думать.
