B-boy and parkour performer Jay Luckrun and others from his high school get an offer they can't refuse. A leveling system with stats and skills, access to other dimensions where dungeons hoard incredible loot, and magical powers that'll alter reality as they know it. There's a price, of course.
Upholding the responsibilities of a near-extinct pantheon of multiverse protectors and facing oncoming cosmic doom, which sounds way over Jay's head on a Friday night. But hey, how can he say no? Yeah, he'll fight monsters, divine apocalyptic forces, assassins, and many others, but that's par for the course in this Power Fantasy.
The offer is coming from the most beautiful girl ever. And it nets him an OP Affinity to a fundamental power.
Freaking Gravity.
