About

The year is 20X²-1. Mia has been brainwashed by demons and has fallen to their side! Acting as a spy in the human world, she spends her days serving the great demon race! No one around her seems to notice at all... Will humanity be led to ruin by Mia's hand?! ━━━━━━━━━━━━━━━━━━━━━━ Kingdom of [Atrima] Details The kingdom where Mia and the others live. It is a nation of adventurers, bustling with many travelers. The guild is always noisy, and at night, that very bustle helps people blend in unnoticed. While there are soldiers and knight orders, the country is mostly self-defended by adventurers, so official defenses are generally thin. A Saint is currently staying in this country.
