In a world scarred by "Dungeon Outbreaks," humanity has evolved into super-powered Espers and Guides, managed by the global organization Blue Lock. Isagi Yoichi, a seemingly ordinary high school student with an extraordinary compatibility rate and a secret "System," is recruited by Jinpachi Ego for Blue Lock due to his near-perfect compatibility with Japan's strongest Espers.

Summary
REBOOT OF SYSTEM SCAN: ULTIMATE COMPATIBILITY
In a world ravaged by Dungeon manifestations, Espers protect humanity at the cost of their sanity. Isagi Yoichi, an overlooked F-rank Guide, is hiding a secret: a System interface, one he must conceal or face fatal consequences. For three years, Isagi has secretly used the System to support his A-rank Esper friends, stabilizing them while pretending to know nothing about their double lives.
Meanwhile, his eccentric teacher, Jinpachi Ego, has been quietly researching him. Unbeknownst to Ego, Isagi is fully aware of the surveillance, and has been carefully maintaining his act.
Everything changes when Blue Lock recruits Isagi for a single reason: his near-perfect compatibility with Itoshi Sae, a volatile S-rank Esper on the brink of losing control. Pulled into Blue Lock’s elite program, Isagi’s carefully constructed lies strain under pressure, and the System itself, begins displaying unpredictable variables.
