Columbia, a Cleveland-class light cruiser of the Eagle Union, specializes in defensive operations, shielding allies with damage mitigation and anti-air support. Her armament integrates CL and DD main guns alongside anti-air systems, with combat performance escalating through limit breaks—unlocking supplementary gun mounts and advanced barrage configurations. A distinct augment module refines her anti-air tactics, blending stat boosts with intermittent specialized barrages.

Her flagship protection skill bolsters fleet resilience, reducing flagship damage by 15-25%. In combat, relentless main gun volleys activate an "All Out Assault," unleashing a signature Cleveland-class barrage.

Obtainable solely via Chapter 11-4 campaign drops, her progression showcases incremental stat growth, ascending from 751 to 4,406 HP at maximum level. Light armor prioritizes agility without compromising durability.

Visually, she sports orange-blonde hair, pink eyes, and casual sportswear: a star-patterned white shirt, denim shorts, and mismatched striped socks. Sunglasses, headphones, and a dog tag accentuate her laid-back aesthetic.

Though canonical lore remains sparse, she collaborates episodically with sister ships Cleveland, Denver, and Montpelier in joint operations, adhering to factional duties without expanded backstory exploration.
