アズールレーン Episode of Belfast

The course of humanity has been completely changed by the appearance of the Sirens, a strange enemy that came from the sea. To counter the unknown enemy, mankind established a military alliance - "Azur Lane". The Sirens' invasion was halted, but not repelled. During the long standoff, differences surfaced between the factions, leading to conflict between them. In the midst of this battle, there is a military port that sits the furthest away from the battleground. There lives a beautiful silver-haired girl who belongs to the Royal faction and works as the chief maid. She is the second ship of the Edinburgh class, the Royal's largest cruiser, and her name is Belfast. Her slapstick daily life is about to begin! (Source: Dash Bunko, translated)
