Guild Handyman? More like Mastermind! Using My Hidden Skills in the Shadows

Synopsis

Unassuming, hard to notice, downright plain—that's how Tenes Lumel's coworkers at the adventurers' guild describe him. As the guild's handyman, he tackles the boring paperwork and menial labor, all while clocking out on time from his quiet job in the boonies. But the low profile he keeps by day hides a darker truth. In reality, Tenes is the mastermind behind a secret organization singularly determined to upend the twisted rules that govern the world. Exiled from a great noble house and abandoned by God, he won't stop until he's dismantled the system. From the shadows come powerful allies to stand by his side: a battle-hardened maid, an infamous bandit, and a legendary dark elf. Together, they're plotting their next move behind the scenes—and Tenes has more than a few tricks up his sleeve to set the stage. (Source: J-Novel Club)
