Versatile Hero in Futuristic World

It all began with a cliché hero story. A world called Terra needed a hero and the king ordered the priest to summon one from another world. Axl, a typical 21-year-old university student, was selected as Terra's greatest hero.

The hard-working hero was able to reach his maximum level in a year and overcome the dark lord. The Dark Lord was defeated. But just as he believed everything was going according to plan, the dark lord trapped him in the crystal and put him into cryosleep.

The hero had been forgotten as the world had once more returned to peace.

A thousand years later, he was awakened from his long slumber by Shea, the princess of the lost Moonstar Empire. He discovered that his surroundings had changed. The space shuttle had replaced the carriage, and the sword was now the lightsaber.

Does a hero like him still have a place in this futuristic world? What does the princess want from him?
