Gass, the Guardian of Time, enforces neutrality to preserve the space-time continuum after Heavenly Beings severed the dimensional bridge between their realm and Earth, halting wars over Akuto—energy born from human emotions. Bound to impartiality yet labeled the "Outsider" for his political detachment, he abandons passive observance when Akuto’s depletion risks annihilating both worlds, intervening directly to save the Magical Kingdom.

Defying his guardianship’s laws, he unlocks the dimensional gate for Munto’s Earthly mission, invoking a self-destructive curse that fractures his body. Accepting this sacrifice, he aids the kingdom’s defense against the United Army, disrupting enemy strategies and compelling adversaries like Leica to question loyalties. His defiance of fate underscores a transformation from detached arbiter to embattled revolutionary.

Beneath his austere demeanor lies a complex duality: a stern enforcer tempered by compassion. He shields Irita, his frequent companion, with quiet devotion and mentors allies, urging them to forsake blind obedience for pragmatic unity. As conflict intensifies, his physical decay manifests in spreading corporeal scars—a visceral testament to his eroding mortality.

Stripped of rank and nearing death, he confronts foes like Gntarl, who weaponize Akuto for conquest. His final acts redefine guardianship, replacing rigid tradition with ethical autonomy, and galvanize fractured factions to coalesce against annihilation. His legacy endures as a catalyst for systemic change, proving duty intertwined with moral courage can avert oblivion.
