Rumble Circuit (Awakened in a Fighting Game World and Forced to Battle to Survive)

Janus Campbell can't fight. And unfortunately for him, that's the only way to survive. Upcoming physicist Janus Campbell is trapped in the world of Tersaia, where shadow monsters lurk the streets, anyone can be monitored at any time and fighting is the best way to make a living; either through the Rumble Circuit, a world-wide ranking of combatants that keeps track of participants' wins and losses in competitive duels, or through slaying the constantly spawning Essencima that terrorize the population. Unfortunately for Janus, he doesn't know how to fight. No special moves. No signature techniques. Not even a basic grab. However, there are two people that might be able to help him out. Itzel, an avaricious woman with the ability to manipulate the wind, and Gurk, a man-crocodile hybrid of few words that can control ice, are the ones that will have to help Janus if they ever want to leave the harrowing alleys of Labrisson and rank up in the Rumble Circuit. Art isn't mine, it's commissioned.
