Something happened… It had long been brewing, and now a virus—surely created by people—has wiped out most of the population. Only those who were inoculated survived. And not just survived—they gained new abilities that were previously unavailable to humans.
As for me, as always, I was unlucky. Though you can look at it from different angles. I got a unique class without a super power and impossible capabilities. But I got something else—something the others don’t have. Now it all depends on me: will I become the coolest of all, or will I die in a ditch.
