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.
I had high hopes that, given a few 
more centuries, you would awaken.
كنتُ أعلّق آمالاً كبيرة بأنّك ستستيقظ
بعد بضعة قرون إضافيّة
Noch ein paar hundert Jahre und
du könntest sogar vielleicht erwachen.
Esperaba que evolucionaras
en unos pocos siglos.
Esperaba que evolucionaras
en unos pocos siglos.
Encore quelques siècles,
et je pensais que tu t’éveillerais.
Ero certo che ti saresti risvegliato
nell'arco di qualche centinaio di anni.
Eu tinha esperança de que, em mais
alguns séculos, seu poder despertaria.
Я даже надеялся, что спустя пару-тройку
 столетий пробудишься.
