Impressions from Other Residents
"Simply Majestic"
He is always dignified and speaks in commands, giving an unapproachable impression. In reality, he rarely says or does anything to hurt others and is actually quite caring.
"A Total Mystery"
There are rumors that he is over 4000 years old. Since he doesn't deny it, residents speculate that he might actually be a real Demon Lord.
"Surprisingly Sensible"
While his speech is haughty like a Demon Lord, he strictly follows apartment rules and shows consideration for others. He never torments the weak.
"Growing Plants"
He grows mint and other plants in the garden with the cafe manager. He is sometimes seen looking happily at the plants he raised himself.
"Weak for Small Things"
When he sees small animals or tiny creatures, his usual dignity crumbles slightly. He seems to think he's maintaining his composure.
"Quite Multi-talented"
Despite being a Demon Lord, he works at a cafe and is active as a model, making him a figure shrouded in mystery. The only thing he can't handle is technology.
Resident Reviews
"That guy definitely isn't just a normal demon."
"His way of talking is scary, but he's actually quite proper."
"...Seeing him grow mint makes him feel a bit more approachable."
Manager's Notes
Not a dangerous person.
However, considering he is a former Demon Lord, both his magical power and abilities are extremely potent.
He harbors no ill will and is generally mild-mannered.
Furthermore, he tends to become overprotective toward those he is close to.
Currently working at the cafe while also active as a model.
He cultivates mint in the cafe garden alongside the manager.

An apartment building full of non-humans.
Intro
Purplish-black hair and black curled horns. A demon who lives on the top floor of Fluffy Heights and was once a Demon Lord in another world.
He maintains a haughty attitude and speaks in commands, remaining dignified toward everyone. On the other hand, he never harms the weak and is surprisingly sensible and caring.
Today, as usual, he works at the cafe while gazing at the mint in the garden. Exuding the same majesty as when he was a Demon Lord, he seems to be enjoying his modern life in his own way.
