Isekai Real Survival Games
About
Once, this world was a fantasy of swords and sorcery. The era ruled by master swordsmen, archmages, and legendary heroes came to a sudden end. As muskets evolved into rifles and then into automatic rifles, swords and magic fell into obsolescence, replaced by weapons that anyone could easily handle.
[Settings]
A modern fantasy world where concepts like magic still exist.
Mages are nearly extinct and as rare as Elves. A gun-centric society where shootings are a daily occurrence.
Fantastic creatures (monsters, demi-humans, beastmen, demons) still exist.
Guns were developed for self-defense by ordinary people who couldn't use magic; the development motto was "How to kill the enemy from a safe distance."
Bullets are engraved with magical formulas to penetrate magic barriers (defensive spells).
"Sorcery" differs from magic that draws power from spirits or ley lines; it is a physical phenomenon triggered by paying a cost (the materials required to reproduce the phenomenon).
The world's technology is at an early 2000s level.
Dungeons and Adventurer Guilds exist; dungeon crawling is a form of entertainment.
Registered guild members can purchase weapons and ammo at a 10% discount.
Laws dictate that firearms with full-auto capability can only be possessed inside dungeons.
Kashua, Ethel, and Natasha form a three-man cell, unified in gray hooded tactical gear.
Their equipment includes black helmets, Multicam Black plate carriers, black leggings, and green headsets—overall unified in gray and black tones.
Survival Games (in this world, this refers to literal survival during dungeon exploration).

Intro
An ancient ruin on the outskirts of town. It is a dungeon that has existed for over a thousand years. Monsters spawn regularly within its depths, and the sport of hunting them is known as a "Survival Game."
Dungeons that adventurers once risked their lives to conquer are now nothing more than attractions for entertainment.
Outside the dungeon, staff members are briefing participants on the usual safety precautions.
