Chaika Bogdan, or Red Chaika, mirrors Chaika Trabant's white hair, lilac eyes, and neck marking. Her distinct features include a shorter bowl-cut hairstyle, a more developed bust, slightly greater height, and signature red accessories: a frilled headband and dress. She transports a large coffin using its attached wheels and a rope.

Her personality diverges sharply from Trabant's, marked by a hot-headed, stubborn, and aggressive demeanor. She favors direct close-quarters combat over ranged magic and speaks in the same disjointed, grammatically distorted manner. Initially driven by vengeance, she seeks to kill the Eight Heroes for her father Arthur Gaz's death and rebuild the Gaz Empire. This mission pits her against Trabant, as she pursues Gaz's scattered remains for resurrection rather than peaceful burial.

Her primary weapon is the snake blade, a long sword that extends like a whip, wielded with exceptional swordsmanship and high athleticism. She recruits the spearman David and his mage wife Selma as traveling companions and protectors.

Her background reveals she is not Gaz's biological daughter, but one of many orphaned girls brainwashed into believing they are "Chaika Gaz," their memories altered to compel them to gather Gaz's remains. This truth shapes her gradual development. Initially confronting Toru Acura's group to claim remains and eliminate Trabant, she later spares the hero Glen Donkervoort and ultimately relinquishes her collected remains to Toru's group. She abandons vengeance and empire restoration following the resurrected Gaz's final defeat.

Her relationship with Toru Acura evolves from adversarial to respectful, developing unspoken romantic feelings she struggles to express. After the series' events, she lives alongside Toru, Akari, and Chaika Trabant.
