High school student Mikoshiba Ryouma was summoned to a different world in the middle of a war. Sensing the malice from the one who summoned him (a summoner of the O’ltormea empire), he uses his martial arts to run away, killing important people of the empire during his escape.

Eric Maddox, a 70-year-old American retired football coach once hailed for his tactical brilliance, now forgotten by time—closes his eyes for what he believes is a normal nap in his quiet Florida retirement home.But when he opens them, he's not staring at ceiling tiles, instead, he's on a touchline.Wearing boots in the rain.With players running on the pitch, fans jeering behind barriers, and the smell of cheap turf pellets in the air.“What the hell is this?”He’s twenty-five again, but it’s not Earth. It’s a world where football reigns supreme. A world where the sport is religion, its practitioners, deities in cleats. Coaches are revered, players are worshipped, and even the kit man gets treated like royalty.But there's one catch: none of it is familiar. The clubs, the players, the leagues, the competitions, and even the currency—they're all different. Alien. Like waking up in a dream where the rules are the same, but the language is foreign.As if that wasn’t enough, the body he’s now in? A youth coach with a laughable win record, a looming divorce, and a measly fifty thousand in the bank that his ex-wife is fighting tooth and nail to take. All of it.Just when the spiral seems inevitable, a monotone chime pierces the noise.[Initiating Golden Finger…][…45%… 75%… 100%][System Integration Complete.][Welcome, host. You are now bound to the Pro Manager System. Objective: Dominate the Football World. A new era begins]From washed-up has-been to chosen one of destiny, Eric Maddox is about to trade arthritis pills for tactical boards, and shuffleboard for Prestigious Cup glory.Because in this world, tactics are power.And on this touchline, he’s about to become a god.

Okay, so let me get this straight. I wake up and BAM, I'm inside the body of Valerian Thorne—a third-rate villain. I mean, come on? Out of all the characters I might have been reincarnated as, it had to be him? This man was literally a stepping stone for the actual hero. So why him? Why not someone with a little more. potential?Now that I have a system that can unleash Valerian's hidden potential, who knows? Perhaps this third-rate villain will get a second chance, alter his destiny, and prove the world what he is truly capable of. And if I happen to get to keep the gorgeous fiancée in the process. well, I'm not complaining.
