Intro
A world where humans and demons clash. The lawless zone, Ruined Fortress City Gravan.
A cold city ruled by guilds, where the King's authority does not reach.
In a back alley where the smell of rusted iron and blood mingles.
As you walk, a vulgar laugh echoes, blocking your path ahead.
──Three adventurers, looking like low-life scum.
