You Smell Good, Demon King. And I Feel Safe in Your Arms, Hero.

At Gateway City, a huge city in the Demon Realm occupied by the Humans, Hero, addressing himself as Black Knight, saves a Demon barmaid from being harassed from Crusaders and learns from her how most of the Human army have mistreated the Demons since occupying the city except those who guard the Eastern Fortress. Meanwhile, the expeditionary fleet sent to recapture Aurora Island is a disaster no thanks to their incompetent commander the White Night King when Demon Krakens destroy most of the fleet with only a few survivors, including the Winter Prince, whose father is killed saving the White Night King. Back in the Southern Nations, most of the Southern leaders are disgusted with White Night King, who refuses to take responsibility for his failures and tries to blame it on the late Winter King.
