Azur Lane: The Siren War and the Hymn of Steel Beasts

War.

War never changes. That much is certain from the countless conflicts in human history, we are drawn to it and relish in it's art. The Azur Lane alliance broke off due to the inability to prevent conflict, there are those seeking war and power while the ones who remain conservative believe in the strength of unity.

In the midst of the Siren War, various anomalies were introduced to the world, these are aftereffects from Siren intervention and the mysterious shipgirls' appearance themselves; Ember and Ash. But, none of those anomalies would be as severe as this. The Commander for the Azur Lane coalition must face uncertainty, doubts and regrets to bring back the other factions together. Having regained communications with Northern Parliament, and the recent attack on the Panama Fortress, the next step would have to be striking key Siren facilities and dismantling their war capability.

However, the shipgirls would find either greater enemies or dependable allies that were brought into their world. Somewhere out there, beyond space and time; the possibility of other shipgirls like them, fighting the same war; against conflict. The Sirens brought war into the world, and thus the hymns of these girls would bring an end to the Siren's ambitions.

「This book is a crossover between Azur Lane, Kantai Collection and Arpeggio of Blue Steel. Most will not be canon except for the mention of certain operations in the event from the Azur Lane mobile game; The Defence of the Panama Fortress for instance. I will be integrating these ideas to make them plausible, so there will be no massive fleet of Fog warships suddenly taking over the world of Azur Lane or the Abyssals arriving there. The Sirens are a big enough threat to humanity, but there will be instances for them to bring reinforcements to stop Azur Lane's advances. Certain OCs belong to me, so if there's any similarities then I apologize. My story can be found in Fanfiction.net too.」
