Overview
Air Defense Princess is an Abyssal ship appearing in the browser game Kantai Collection. She debuted as the final boss of the last sea area in the Summer 2015 event, Counterattack! The Second Operation SN. Although classified as a destroyer, she possesses extraordinary defensive capability and anti-aircraft power that far exceeds standard expectations for her ship type. Her visual design was created by illustrator Shizuma Yoshinori.
Appearance
She has long white hair and thick, curved horns resembling those of a sheep, with a torn ribbon wrapped around her head like a headband. Her design features a white and red color palette paired with a fitted black bodysuit adorned with spiky metal components at the neck and chest. The outfit features exposed skin around the midriff and upper legs, black gloves with sleeve-like detailing, and heavy boot-like gaiters connected to thigh rings with anchored chains. A thin red cloth flutters under her arms. Her rigging includes four living high-angle gun units with eight barrels, alongside a fifth biological unit she mounts for movement.
Personality
She exhibits an arrogant and provocative demeanor, openly mocking her opponents during battle. She takes delight in inflicting pain and displays supreme confidence in her overwhelming defenses and firepower. However, when she takes damage herself, her composure breaks into a childish and vengeful frustration, reacting with immediate hostility toward her attacker.
Abilities
Despite her destroyer classification, she possesses exceptionally high armor, firepower, torpedo stats, and devastating anti-aircraft capability. Her extreme anti-air capability allows her to neutralize incoming enemy aircraft, while her armor stat exceeds standard night-battle damage caps. In combat, she is capable of leading elite battleship-class Abyssal units as escorts to deliver heavy combined fire.
Background
She first appeared in the summer 2015 limited-time event, Counterattack! The Second Operation SN, serving as the final obstacle at the deep end of the ultimate operation area. She later reappeared in subsequent event operations, such as the Autumn 2017 event. During her debut campaign, defeating specific supporting enemy supply lines and logistical hubs unlocked defensive reduction mechanisms required to effectively breach her armor.
Relationships
Defeating Air Defense Princess allows players to encounter and rescue the Akizuki-class destroyer Teruzuki. Due to striking similarities in visual design and equipment configuration, she is widely associated with Akizuki-class destroyers like Akizuki and Teruzuki as an Abyssal counterpart. In battle, she frequently appears alongside heavy escort units such as Battleship Princess.
Trivia
Among the player community, she is commonly referred to by fan nicknames such as Waruzuki. Due to her extreme anti-aircraft effectiveness, players often compare her weapon systems to modern naval defense platforms and Aegis-equipped vessels.
