Hero, disguised as Black Knight, causes the Crusader army in Gateway City to have nightmares in order to decrease their moral. Meanwhile, in the Southern Kingdom, Winter Prince ascends to the role of Winter King after his father passes away and begins the second battle to reclaim the Aurora Island with Female Knight leading the Winter Kingdom’s army. Demon King then appears, carrying a secret that would influence the outcome of the war.
(From the official episode guide)
Demon King shares with Elder Sister Maid the many facets and wonderful events that are interconnected with conflict and the possibility of humans and demons living peacefully together at the end of the war.
The Southern Kingdom, which would collapse without the funding from the Central Kingdom, fights to reclaim Aurora Island from the Demons to open up more trade routes and rid themselves of their dependency.
Demon King joins Female Knight at Aurora Island, and the battle progresses in their favor. However, blocking their way is the fearsome and well-known Demon, Arctic General!
This episode won fans over with the battle between the impressively strong Arctic General and Female Knight, as well as the scene in which Hero is reunited with Old Man. How will the story develop in the next episode?
