Fist Fighters.

A tribe that, for hundreds of years, had explored the true nature of one’s physical body.

Both the swordsmen and the sorceresses considered the summit of all arts to be ≪interrupting a target with Incarnation≫. In other words, overwriting external events with imagination.

However, Fist Fighters thought the opposite — strengthening their own bodies with Incarnation. Surpassing their original limits, they would strengthen their naked bodies with defensive force stronger than steel, and wield their fists with attacking power enough to crush boulders.

And, of course, they would train their legs to run faster than horses, while barefoot.
