Miguel is a brash, highly skilled swordsman who partners with fellow treasure hunter Rasha, rivaling the main protagonists. Renowned for his boastful swagger, he loudly proclaims invincibility in battle, insisting no foe has ever struck him and inflating past triumphs—such as vanquishing fifty cavalrymen alone. Beneath the bravado lies authentic mastery; he hones Lyle and Ihrie’s combat skills to bolster their prowess against enemies.

His alliance with Rasha maintains a veneer of professionalism, though glimpses of concealed concern for her surface amid their rivalry. A running gag underscores his overconfidence: he initially misidentifies Ihrie as male during their clash, only realizing her gender after her armor fractures mid-fight.

Driven by self-interest and a pragmatic alliance against the greater menace of Ruguduroll, Miguel aids the united quest for the Ultimate Power. Though his origins remain untold, his tactical contributions prove pivotal in defeating the antagonist. Post-victory, he departs with the disbanded group, his future endeavors left open-ended.
