In a tranquil era free from Sirens or warfare, shipgirls from various nations coexist peacefully. Among them, destroyers like Ayanami, Javelin, Laffey, and Z23 focus on their studies, while others engage in diverse activities such as sports, foraging, training, formal events, and competing for the Commander's attention. Despite their different interests, these girls share a strong bond of friendship, dedicated to strengthening their connections within the serene setting of Azur Lane.
