Saki Nikaidō, former leader of the all-female biker gang Dorami, perished in 1997 during a fatal cliffside motorcycle clash against rivals. Resurrected as Franchouchou’s undead idol, her indomitable spirit endured beyond death at eighteen. Her zombie form boasts bluish-gray skin, crimson eyes, scars along her left cheek, arm, and leg, and bandages draping her torso and limbs. Human disguises revive her original golden eyes via contacts, accenting blonde hair with orange highlights tied in a high ponytail.

Famed for her fierce demeanor, Saki mocked those lacking “guts” yet softened to console struggling comrades. Her natural leadership in Franchouchou mirrored Dorami’s Kyushu dominance. Beneath her tough exterior lay a collector of Tamagotchi, a drive-in diner enthusiast favoring chicken over sweets.

Expanded backstory episodes rekindled ties to ex-gangmate Reiko and Reiko’s daughter Maria. A Korosuke gang rematch reignited rivalries, showcasing her loyalty to Dorami and growth from seeking control to valuing bonds. This pivot marked her shift from solitary rebel to a leader prioritizing collective triumph.

Zombie traits granted Saki hyper-rotating limbs and impact resistance, surviving crashes unharmed. Combined with combat prowess, she disarmed foes and executed acrobatic concert stunts, her resilience fueling Franchouchou’s performances.

Later arcs highlighted her unifying role, exploring Dorami’s origins and the significance of her “Legendary Kamikaze Squad Leader” title. These threads traced her evolution from personal glory to fostering camaraderie, aligning her rebellion with Franchouchou’s mission to resurrect Saga.
