(No harem, no System, not a wish-fulfillment story. A traditional, retro fantasy setting. Enter with caution if that's not your thing.)
Swords and guns clash, technology collides with magic. This is a chaotic continent, home not only to humans but also to all kinds of demi-humans, evil spirits, and even demons. The different races have formed small kingdoms that wage war on one another without end.
On this chaotic continent, there is a profession known as the Ranger. Their modified bodies give them lifespans far beyond those of ordinary humans, and their long lives offer more opportunities to learn. They can wield magic and potions, master all kinds of melee weapons, and even command the undead to offer sacrifices and summon demons to fight for them. They also make use of human technology, riding advanced vehicles and killing with firearms.
They hunt demons and evil beasts, pursue criminals for bounties, and even assassinate the powerful. These are all simply means of pursuing profit.
For Rangers, the most important rule is that there are no rules.
