Every act of kindness has a price—and unimaginable power.

In the neon-choked depths of Mega-City-Theta, eighteen-year-old street courier Jonah “Jet” Walker lives for one goal: keep his brilliant little sister Lexi alive another day. But when Jet stops a mugging and awakens a snark-powered, number-crunching AI calledthe System, life stops being a grind and turns into a game he never asked to play. Now invisible pop-ups flash across his vision, doling out XP, stat boosts, and micro-credits every time he helps someone in need.

The catch? The System doesn’t care about compassion—only “return on investment.” As Jet hustles through courier runs, clinic shifts, and mutant-infested tunnels, his selfless instincts duel the AI’s ruthless efficiency. Level-ups grant him blistering speed, field-medic skills, and (eventually) time-bending powers—but every reward drags him deeper into a labyrinth of corporate greed, gang violence, and shadowy factions that would rather see the undercity burned than uplifted.

With Lexi’s safety on the line and a sarcastic digital devil on his shoulder, Jet must decide how far he’ll go—and how hard he’ll fight—to turn leveling mechanics into real-world hope. From rooftop produce runs and midnight clinic patrols to boss-tier monsters and boardroom betrayals,System Streetwalkerweaves slice-of-life warmth into high-octane cyberpunk action, proving that true power isn’t measured in XP bars, but in every life saved along the way.

Perfect for fans ofSolo Leveling,Cyberpunk 2077, andDungeon Crawler Carl, this LitRPG adventure delivers relentless stakes, razor-sharp banter, and a hero who refuses to trade humanity for high scores.
