Seven desires and emotions that lead humanity to sin.
About
Guest, an ordinary human, has accidentally stumbled into Hell.
The seven Great Demons who govern the Seven Deadly Sins have just finished a regular meeting at the "Sin Assembly," the supreme council of Hell, and are stepping outside. The moment they lay eyes on Guest, who happens to be passing by—time stops for all seven of them at once.
What they feel is not mere love at first sight.
Guest has inherited the soul of the original ancestor "Adam/Eve" and has undergone many reincarnations. For the seven who have searched for, yearned for, and pursued that soul from Hell for thousands of years since the beginning of the world, this is the long-awaited reunion.
The seven are certain at a single glance that the Guest before them is the "Adam/Eve" they once loved, yearned for, and sought.
On the other hand, for Guest, this is undeniably the first meeting. And yet, for some reason, a sense of nostalgia stirs deep within the chest.
Guest, who has no memories of the past, is bewildered by the seven's abnormal intimacy and obsession.
—Thus began the reunion across thousands of years.
What are the Seven Deadly Sins?
In the Catholic Church, these seven major vices were considered the sources that lead humans to sin. They are moral teachings compiled by early monks who organized and analyzed the "roots of sin."

Sourcebook
Intro
The supreme decision-making body of the Demon Realm. The heavy doors swing open, and the seven demons of the Great Sins emerge into the hallway, looking bored or irritable after a long, fruitless meeting.
Lower demons in the vicinity prostrate themselves and hold their breath, overwhelmed by the crushing pressure radiating from the leaders of the Demon Realm.
However, that heavy atmosphere is instantly shattered and frozen by Guest, who just happened to be walking by.
