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 should have just laid low, 
as you told me to.
كان يجدر بي أن أبقى متخفّياً كما أخبرتني
Debí quedarme quieto,
como propusiste tú.
Debí quedarme quieto,
como tú me dijiste.
J’aurais dû suivre tes conseils
et rester à ma place.
Avrei dovuto ascoltare il tuo consiglio
e starmene tranquillo.
Eu deveria ter ficado quieto no
meu canto, como você me avisou...
Как ты и сказал…
мне следовало остановиться.
