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.
And that's how I became a part of 
Octagram, the eight Demon Lords.
وهكذا أصبحتُ جزءاً من أوكتاغرام، أسياد الشيطان الثمانية
So wurde ich einer der acht Dämonenkönige,
ein Mitglied des Oktagramms.
Y así es como pasé a formar parte
de las Ocho Estrellas: Octagram.
Y así es como pasé a formar parte
de las Ocho Estrellas Demonio: Octagram.
C’est ainsi que je devins
un des huit rois-démons de l’Octagramme.
Ed è così che io
E foi assim que me tornei parte do
Octagrama, os oito Lordes Demônios.
И вот так… я стал одним 
из Князей Тьмы «Октаграммы».
