JUMPER

"You want to be a Hunter, right?!"
Marcus Koa had been asked this question almost every day since he was little. His father had asked the question; his mother had asked the question, while she was still conscious.

But Marcus never had the talent. He never awakened a system window. For fifteen long years, he acted as a pack mule, a porter, to gather money to hopefully keep his little sister fed and to pay for his mother's medical bills.

But one day, during a routine E-Rank dungeon raid, his entire raid group was killed except for him and the leader, Marie.
Instead of dying, he awakened the ability to "Jump," and the system mis-categorized him and his ability. Marcus became one of the first people to awaken as a System User at 29 years old.

Now with the power to save his mother and keep his sister fed, why hide it? He's a JUMPER now.
