Sztorm finds herself bored while attending on of Azur Lane's parties, but she knows just the thing to end her boredom.

Bored from work, the Commander takes to peering through his binoculars in search of some distractions. He finds one in the form of a topless Enterprise in her dorm room - the accidental peek leading to something much more risqué. [Smut]

Spring, 1916. The Great War has ground into a stalemate. In a desperate bid to break the dreadlock, the German Empire turns to the sea, hoping to break the Royal Navy's blockade and reopen their ports to badly needed neutral trade. And perhaps the glowing blue cubes that they've received will provide just the edge that they need... (The Battle of Jutland, with Shipgirls)

A mystery man is discovered at sea. but what will this change?

Post apocalypse... check. Sirens... check. Kansen...check. In a world that has finally succumbed to the Sirens. One man will face his hardest task as the last free man on earth. Saving his planet from the aliens who sought to enslave it.

Taking a short reprieve from his duties the Commander, accompanied by U-47, hop on their bicycles and take a small trip around the coast. With the unrelenting summer sun overhead the pair soon take a break in a shaded bus stop... and, after a chance glance, decide to make use of their privacy. [Smut]

With war on the horizon, Azur lane reopens their Pacific base and calls for workers from the civilian sector, leading one young girl to quickly discover she was not what she thought, and that her long lost mother was far from what she thought. life is complicated when one discovers they are the daughter of a fabled ship-girl, and one themselves, after all.

Lusca had done it, he had finished his mission, and with the last of the Siren Bases destroyed, he could find peace in the Abyss. at least that was before the Sirens found him, and decided to torment him just a bit longer. they sent him into another time line, and while some things are the same, a great deal more are very different. How will our Monster handle this new world?

The Liberty Festival, made to both celebrate the dead and humanity's continued victories against the Sirens, had come to Hawaii once more. And with it Arizona found herself participating in the festivities, clad in naught but traditional attire. She certainly didn't expect to run into an old friend, however. [Smut]

The Sirens attacked Earth, while WW2 was underway and decimated all navies. But, humanity managed to reestablish a few island bases. Will they take back all the seas from their grasp? This story follows the story of one commander and his men from Eagle Union, created from the ashes of the US.

With summer waning the Commander decides to take a much-needed vacation to the beach, whisking along both his wife Kawakaze, and her sisters. Only he didn't expect to get extra physical with them whilst there - not that he was complaining. [Smut]

Acquiring some ever-desired time away from the office, the Commander whisks himself and his partner Allen to an onsen-inn located up a nearby mountain, intent on soaking away all the stress. Naturally, soaking isn't the only thing they end up doing. [Smut]

Commander Karl Dael is assigned to Azur Lane as an "Active Rest" from his combat tours on Tiberius. While the Order assures him its for his best interest, he worries that there is more going on. His past catches up to him as new META ships begin to hunt him. Through all this, he fights his inner demons from the wars and manages the ever-changing dynamics of the Port.

Things always happen in the Big Apple.

the Commander's journey to the Azur lane port is becoming a catastrophic event as an unknown shot out of nowhere hits the commander. But the shot is not killing him but instead shrunk him to 3 inches tall? Musashi also there too, and now it depends on her and the others who knows to take care of the commander until he gets normal. (size fetish and giant girl warning)

Welcome to A.L.I.B.I the Azur Lane Intelligence Bureau of Investigation, a private investigation group tasked with solving the criminal shenanigans of multiple shipgirls while navigating the bureaucracy of the Royal Knights

The Commander isn't quite alright...

Badly written smut of the common shipgirls.

The Commander had been stationed in the Sakura Empire for no more than a few days before Shimakaze whisked him away to their latest attraction - a bunny bar. One that featured many familiar faces, amongst them Suruga, who the Commander quickly gets reacquainted with... [Smut]

When they fly together, they soar to greater heights.

Stuck in his office doing tiresome paperwork, the Commander remarks on how entertaining it is to get a letter from Mutsuki and her sisters. A remark that earns him Hatsuzuki's attention, in more ways than one. [Smut]

One author's take on the war and world of Azur Lane.
