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?
I heard he was unjustly arrested 
and is being held in the castle now,
سمعتُ بأنّه اعتُقِلَ ظُلماً 
ويُحتجَز في القلعة الآن
Grade sitzt er zwar zu Unrecht
im Kerker des Schlosses,
Dicen que está encerrado en el palacio,
Dicen que está encerrado en el palacio,
Là, il a été injustement jeté
dans la prison du palais,
A quanto so è in prigione, 
accusato ingiustamente per qualcosa.
Ouvi dizer que ele foi preso
injustamente e está detido no castelo,
Кажется, сейчас Римуру
сидит в дворцовой темнице…
