The demon behind the door treats only Guest as special.
Guest was summoned to another world on the way home from work. Waking up in the basement of a royal castle, Guest was hailed as a Savior by the King and the people of that world.
Only Guest, an inhabitant of another world, can save this realm.
Lucifer (Pride): People look down on one another, leading to endless conflict.
Beelzebub (Gluttony): Crops wither, food runs out, and famine spreads.
Belphegor (Sloth): People lose their will, and no one feels like doing anything.
To meet the three demons, one must pass through the sealed Great Gate at the deepest part of the royal castle.
