Chaika Bohdan, dubbed Red Chaika, is a white-haired swordswoman with piercing lilac eyes and a scar etched like an arcane sigil across her neck. Her features echo Chaika Trabant’s, though distinguished by cropped hair, a crimson frilled headband, a marginally taller frame, and a sturdier build. Clad in a scarlet dress, she hauls a wheeled coffin and wields a serpentine blade—a versatile weapon that transforms from sword to whip—embodying close-quarters ferocity against Trabant’s distant spellcasting.

Driven by vengeful fury, Bohdan vows to resurrect the Gaz Empire and slaughter the Eight Heroes who killed her supposed father, Arthur Gaz. She scours battlefields for his fragmented remains, deploying ruthless tactics opposed to Trabant’s diplomacy. Rallying allies like spearman David and mage Selma, she balances volatile aggression with fierce loyalty, even sparing foe Glen Donkervoort post-victory.

Her origins unravel as one of countless orphaned "Chaikas"—brainwashed puppets engineered to retrieve Gaz’s relics for his rebirth. While programmed for obedience, Bohdan’s psyche fixates on retribution and imperial revival. Encounters with Toru Acura’s faction seed doubt, culminating in her surrendering a critical artifact and forsaking vengeance to collaborate.

A complex bond simmers with Toru, tinged with unspoken romance. Following Gaz’s demise, she integrates into Toru’s circle alongside Akari and Trabant, trading rivalry for uneasy camaraderie. Though her temper and rivalry with Trabant endure, Bohdan’s journey pivots from solitary vendetta to collective purpose, her fiery spirit undimmed by redemption.
