The Janitor Is an SSS-Rank Mech King

Slum janitor's touch wakes legendary mecha, forces all machines to kneel
Leo endures the degrading crawl between a bully's legs just to reach the psychic aptitude exam in the Lower City. His palm brushes the testing crystal and a blinding pillar of light erupts through the ceiling. Thunderbolt, a mythic mecha silent for years, roars awake while every surrounding unit drops to one knee in submission. The system brands him with the rarest SSS-rank designation, flipping his world from crushed underfoot to commanding the mightiest machine ever built.
