Hayato Kongōji, born January 24, 2050, operates as the wind attribute crusher within the Gaist Crusher Garrison at age 14. His combat approach merges lightning-fast strikes and evasive maneuvers, channeling wind-based techniques through Gaist Gear such as Wind Garuda and Storm Garudia. Calm precision defines his demeanor, though interactions with teammates—particularly Rekka’s boundless energy—occasionally disrupt his disciplined composure.

A prodigy of the GCG Academy, he holds dual roles as assistant master of the Kongou Choujin Style temple dojo and a frontline combatant. His younger sister, Kohaku Kongōji, collaborates closely with him through her work in the GCG Science Division, their bond rooted in shared dedication to their missions.

Hayato’s signature Secret Technique: Whirlwind Palm of Gold exemplifies his offensive-defensive balance, while his God Baldur Gear amplifies wind manipulation. The Extreme Form of his Gear grants temporary Gaist-like power at a cost—intense physical strain and volatile control risks.

His speech patterns frequently incorporate "golden" as a descriptor, mirroring his pursuit of flawless execution. Names hold symbolic weight: his surname ("Adamantine Temple") reflects unyielding discipline, while his given name ("Swift Person") aligns with his wind mastery.

In missions, he orchestrates tactical maneuvers against Gaist incursions and clashes with adversaries like the Erasers. Analytical foresight drives his strategies, though high-pressure scenarios sometimes reveal cracks in his stoic precision, grounding his role as both strategist and sparring partner within the team.
