In this world, when you turn 12, God gives you "talent"... While everyone else was given the cool "talents" of "Swordsman" and "Witch," the talent that the main character Rivele received was "Effort" that nobody had ever heard of...!?

On the other hand, his childhood friend Anna received the skill "Dragon Knight," one which is destined to be used in battle. Rivele resolves, "I will protect Anna." Thus, to keep her away from battle, Rivele aims to be the strongest in the world with his overwhelming effort!!
