A story about a mage living in a small town on earth who picked up a pure demon and raised him at home.
One is a law-abiding person who practices mysterious rules.
One is a lunatic who has offended three orthodox churches.
When the moonlight covers the earth;
When destinies begin to intertwine.
The strangers who possess the "system" will be their common goal.
An object to be eliminated, or a wretch in need of redemption?
Everything is still unknown.
Welcome to the City of Moonlight.
Purpose: Anti-system, anti-infinity
