Rimuru confirms that it was Gustav who cursed Zenobia with illness. It turns out he and his accomplice, Carl, are Archdemons plotting to manifest their god using Zenobia as a vessel. Can Rimuru stop them before the Kingdom of Coleus is lost?
It was Gustav who brought all 
that suffering upon me!
!كان غوستاف من أنزل كلّ هذه المُعاناة عليّ
Gustav war es, der mich gequält hat.
Mon tortionnaire, c’est Gustav !
Quello che mi ha fatto del male è Gustav!
Quem me causou todo
aquele sofrimento foi Gustav!
Все мои беды — от Густава!
