Ignacio Axis, illegitimate son of King Gregorio La Hire of the Balsteros Empire, stands as half-brother to crown prince Karl La Hire (later Kal-el Albus). Political upheaval forced his exile alongside his mother; her death one month later forged his deep-seated hatred for the royal family and ignited a consuming desire for revenge.

He assumed the role of devoted bodyguard to Nina Viento (later Claire Cruz) during childhood, safeguarding her pivotal role in the Wind Revolution that toppled the Balsteros monarchy. This duty persisted through his enrollment in Cadoques High's Aerial Division and placement within the elite "Van Whyl" class.

Initially cold and aloof, Ignacio became Ariel Albus's flying partner by default. Ariel frequently teased him as a "tsundere," recognizing his detached exterior masked deeper complexity. Her persistent interactions gradually softened his rigid demeanor, though he maintained a rivalry with Kal-el, initially unaware of their blood tie.

Amid the Sky Clan conflict, Ignacio engaged in critical battles, leveraging strategic prowess and sniper skills exemplified by precise headshots eliminating Sky Clan paratroopers. His unwavering loyalty remained with Claire/Nina, yet survival demands against the Sky Clan forced reluctant cooperation with Kal-el. This culminated in a shift from vengeance toward reconciliation, particularly with Kal-el, as both confronted their shared lineage and past.

Ignacio's contributions expanded beyond bodyguarding to active defense of Isla, volunteering for perilous missions like reconnaissance escort. His character arc traces a transition from isolation to integration within the Cadoques community, driven by Ariel's persistence and the necessities of wartime camaraderie.
