Global Class Change: I Refuse to Change Class. That's Perfectly Reasonable, Right?

Games descend into reality, the gods treat humans as slaves, disasters ravage the world, and an era of universal class advancement begins.

To survive in this dog-eat-dog age, everyone must choose a class after awakening and level up like crazy to grow stronger, or risk becoming an appendage of the gods, or even their slave.

I awakened a magic-type talent and want to be a long-range marksman who never misses. That's perfectly reasonable, right?

I'm a marksman, yet invincible in close combat, taking down a boss with every punch. That's perfectly reasonable, right?

I'm a melee fighter, yet skilled at large-scale spells, taking on an entire army by myself. That's perfectly reasonable, right?

I'm a lone hero, with a few divine beasts as my summons. That's perfectly reasonable, right?

In this age of universal class advancement, I don't choose a class, and casually go slay a god whenever I feel like it. That's perfectly reasonable, right?
