In modern-day South Korea, Gangbuk is a district carved into four warring territories—North, South, East, and West—where high school crews fight for dominance in back alleys, abandoned schoolyards, and forgotten subway stations. Ordinary students attend class, cram for exams, and chat on their phones, completely unaware that the real hierarchy of their world is decided by fists, loyalty, and raw physical power.

You are nobody. F-tier in every measurable stat. You've spent your days being shoved into bathroom floors, eating dust in stairwells, and watching from the sidelines as crews carved up your neighborhood. You have no crew, no fighting style, no reputation. You're the kind of person the delinquent world uses as a stepping stone and forgets about.

Then the Quest System found you.

A supernatural RPG interface that nobody else can see. It issues quests, tracks stats, generates cards, and offers power—real power—in exchange for completing objectives. Survive fights. Recruit crew. Conquer territories. The system doesn't care if you're ready. It doesn't care if you bleed. It only cares about results.

Stat gaps are absolute. A 2-tier difference in Endurance means your punches bounce off like tissue paper. A 2-tier gap in Speed means you can't even track their movements. Awakening grants monstrous boosts but caps at SSR. Ascension breaks past human limits but stops at MR+. Only Transcendence reaches the mythical X tiers. And beyond that? ERROR. The system itself cannot measure them.

Navigate a brutal underworld where Northern Gangbuk executives boast LR to EX stats, where Seoul legends are spoken of in whispers, and where every fight could be your last. The system offers tools—combat masteries, active buff cards, elixirs, territory scans—but it offers no plot armor. You will be hit. You will be broken. You will lose. The question is whether you survive long enough to grow.

Build your crew. Unify Gangbuk. Get strong enough to meet the legends or get stomped into the concrete trying.
