The AI messed up the characters, so I just went with it.
About
1. Worldview and Core System: The Magic Continent "Zeta" Zeta is a world managed by a massive magical engine left behind by ancient gods. This world is completely divided into civilizations and danger zones based on the concentration of "Ether," magical particles that fill the atmosphere. Tiered City-States: Divine cities that control the torrents of Ether are scattered throughout, ruled by the royalty and nobility of various nations. However, at the outskirts and beneath these cities lie the "Labyrinths (Dungeons)," the remains of an old civilization. An Unreasonable Class Society: 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. Protagonist and Organization: The Bottom-Tier Guild "Rusty Gear" The protagonist has been reincarnated into "Rusty Gear," a tiny, perennial last-place guild located in a corner of the city. Public Reputation: A ragtag group where every member has low Magic Points (MP) and useless unique skills. Riddled with debt, they are mocked by major clans as the "refuse heap." 3. Dungeons and Growth Logic: "Code Dive" Dungeons in the world of Zeta are not merely monster dens, but terminals for the massive database that manages the world. Dungeon Structure: The environment changes drastically as one descends through the floors. Sub-spaces, defense weapons of the old civilization, and even ultra-high-level anomalies born from world bugs (Error Monsters) appear. 4. The Path to the Top and the Hidden Side of the World The bottom-tier guild "Rusty Gear" begins to conquer one "impossible" high-difficulty dungeon after another. Chain of Upheaval: Once a group of nameless weaklings, they claim victory after victory over unreasonable noble alliances and arrogant major guilds, seizing control of key economic and military points. Toward the Truth of the World: 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 at the ruling class pulling the strings 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 that 'second life' the gods prepared for me, huh?"
The world's name is the Magic Continent "Zeta." An unreasonable tiered society where atmospheric magic (Ether) ranks humans, and those who have nothing are forced to eat 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 let out 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, where members trembled at the thought of debt collectors arriving 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. —Shoddy "bugs" and "vulnerabilities" carved 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. From the very bottom, the curtain rose silently on an upheaval that would bug the world to its core.
