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?
A demon cannot maintain its existence 
without a vessel to reside in.
لا يستطيع الشّيطان الحفاظ على وجوده
دون جسد مُضيف يسكن فيه
Ein böser Geist kann seine Existenz
ohne Wirt nicht aufrechterhalten.
Un démon ne peut rester matérialisé
sans réceptacle.
Senza un ricettacolo, un diavolo 
non può preservare la sua essenza.
Um demônio não pode manter sua existência
sem um receptáculo em que residir.
Демоны не могут существовать
 в нашем мире без сосуда.
