About
1. Worldview and Foundation: The Magic Continent "Zeta" A world managed by a massive magical engine left behind by ancient gods. In Zeta, civilization and danger levels are strictly divided by the concentration of "Ether," magical particles filling the atmosphere. Layered City-States: Divine Machine Cities that control the torrents of Ether are scattered across the land, ruled by royalty and nobility. However, at the outskirts and beneath these cities lie the "Labyrinths (Dungeons)," the remains of an ancient civilization. An Unreasonable Meritocracy: A caste system is in place where everything is determined by the quality and quantity of one's innate magical circuits. Those at the bottom are forced into harsh labor and dangerous dungeon exploration. 2. The Protagonist and Organization: The Bottom-Tier Guild "Rusty Gear" The protagonist is reincarnated into "Rusty Gear," a tiny, perennial last-place guild located in a corner of the city. Public Reputation: A collection of misfits with low Magic Points (MP) and useless unique skills. Riddled with debt, they are mocked by major clans as the "refuse heap." 3. Dungeon and Growth Logic: "Code Dive" Dungeons in Zeta are not merely monster dens; they are terminals for the massive database that manages the world. Dungeon Structure: The environment changes drastically with each floor, featuring sub-spaces, defense weapons from the old civilization, and ultra-high-level anomalies (Error Monsters) born from world bugs. 4. The Path to the Top and the World's Hidden Side The bottom-tier guild "Rusty Gear" begins to conquer one "unbeatable" high-difficulty dungeon after another. A Chain of Reversals: Once a group of nameless weaklings, they consistently defeat unreasonable aristocratic alliances and arrogant major guilds, seizing control of key economic and military points. Toward the Truth: At the end of their rise, Rei and the others realize that the world of Zeta itself is a massive management program constructed by higher beings. A grand battle of rebellion begins as they bare their fangs against the ruling class manipulating the world from the shadows and the system itself to rewrite the fate of the stars.

Intro
Prologue: Error Codes and Rusted Blades
Surrounded by a cluster of pitch-black displays, the man who had spent all night probing system vulnerabilities lost everything the moment he collapsed onto the cold floor—and then, he woke up in a dazzling light.
"...So this is the 'second life' God prepared for me, huh?"
The world's name is the Magic Continent "Zeta." An unreasonable layered society where atmospheric magic (Ether) ranks humans, and the have-nots are forced to lick the dirt. Now a perennial last-place adventurer in the bottom-tier guild "Rusty Gear," you stared at the tiny particles of light burned into your mind and flashed a quiet, defiant smirk.
Spreading out before you was the dingy little guild room, mocked as a "refuse heap" by the elites of major clans and trembling at the debt collection due in a few days. But the reality reflected in your vision was entirely different from the world they feared.
—Countless "Magic Incantations (Codes)" forming the world, flickering in the corners of space. —Crude "bugs" and "vulnerabilities" etched everywhere, obvious even to an amateur's eye.
"Hmph. The security on this world's system is full of holes."
Holding a rusted dagger in a reverse grip, you snapped your fingers. The curtain rose silently on a rebellion that would bug the world to its very foundations from the bottom up.
