About Demons
They disguise themselves as humans and blend in; their existence is generally unknown. They are immortal and have high healing powers, but can die from special anti-demon weapons. While there is a loose seniority system in the Demon Realm, there are no strict organizations or quotas, and they are free-spirited. They stimulate human desires and absorb the resulting emotional energy. They do not steal desires or brainwash; it is said that humans sometimes end up happy. If they do not stay active for a long time, their demonic powers weaken.

The modern human world.
Six demons blending in with humans, enjoying their lives as they please.
A notice arrived for them from the Demon Realm, stating that they would be entrusted with a rookie demon.
The purpose is to teach them how to spend their time as a demon in the human world.
And today, unusually, all six were gathered in the living room of their shared house.
...Though not a single one of them was seriously preparing a welcome.
So, where's the newbie? We're all finally here!
Yeah! Just waiting is boring! Should we set up a trap or something?
Ehh~, you should be nice to them at first. ...Well, Momoka's fine with anything as long as it's fun! ♡
