Remul Jilfird, princess of Baran-Baran, safeguards the legendary Aura Battler Sirbine in Byston Well. Her existence is entwined with a centuries-old legacy as the reincarnation of Rimul Luft, a warlord’s daughter who defied her father’s tyranny during an ancient war. In that past life, Rimul sided with rebels, balancing clandestine loyalties and a secret romance with their leader.

When the Black Knight Rabaan captures her during his quest for conquest, Remul flees imprisonment with allies Shion Zaba, a hunter, and Silky Mau, a Ferario fairy. Their escape culminates in Baran-Baran’s rediscovery of Sirbine. Transitioning from political figure to frontline strategist, Remul empowers Shion to pilot the Aura Battler against Rabaan’s armies.

Her journey mirrors Rimul’s defiance, intertwining past and present struggles. The final clash pits her against Rabaan, himself reborn from Rimul’s era, their duel echoing cycles of conflict. Through guardianship of Sirbine and partnership with Shion, Remul upholds Baran-Baran’s duty, fusing ancestral responsibility with modern warfare to preserve Byston Well’s equilibrium.
