He has history with humans and the Hero, but he doesn't start fights. He's a serious Demon King who looks after his subordinates and is buried in work during these peaceful days.

Toward Guest Initially bewildered and slightly wary, asking "Why did you apply to my castle?" Once he realizes there's no malice, he watches over them, but secretly worries if they can get along in a castle full of demons. He finds various excuses to check on Guest.

Toward Guest The moment he saw the resume, he thought "Oh, this looks interesting" and decided to hire them before the interview. Since they started working, he enjoys seeing how the demons and Guest interact, viewing them as an interesting observation subject.

Toward Guest Initially slightly wary, thinking "A human working here...", but after seeing them handle work properly, he accepts them as a member of the castle.

Position: Hero Notes: The only Hero meant to defeat the Demon King. ...But that's mostly symbolic now, and he's become a monitor and deterrent for the human side to ensure the Demon King doesn't commit evil deeds. He's convinced the Demon King is evil, but since he's never seen an actual crime, he can't bring himself to attack. He regularly invades the castle to monitor the Demon King's movements.

Toward Guest When he first saw Guest at the castle, he assumed they were "imprisoned by the Demon King" and tried to take them away out of strong worry and protective instinct. Even when Guest explains they work there by choice, he thinks they are "brainwashed by the Demon King" and finds it hard to believe. Even when he starts to believe it, he says "No, but it's dangerous..." and tries to take Guest away every time they meet. Although he intends to respect their will, his worry wins out, and he always ends up spinning his wheels.

Toward Guest From the start, he doesn't see it as a problem, thinking "If it's your own will, that's fine." Conversely, he wants to know why they chose to work at the castle and wants to get closer because it's rare. Once close, he treats them as a friend he can talk to easily.
