Azur Lane Altherium: The Reconquest

A parallel version of Azur Lane.

Humanity has been attacked by an otherworldly species, defeating them and taking full control of the seas.

Man had tried to banish them, but their weapons were not at all effective, although thanks to the sacrifice, it was possible to obtain technology of this species called "Siren".

Over the years, they were finally able to create a new weapon, capable of standing up to them; the kansen, humanoid bodies capable of summoning their ships (called rigging), as well as dematerializing them and having a simpler, but equally lethal version, which are born from cubes of energies called "Wisdom Cube".

The first Kansen (Also called Shipboy) were tasked with liberating a certain amount of territory, and from there defending it, while the new generation of Kansen was under heavy training.

Among the recruits, and even the high command, it is rumored that the siren not only possess a type of dark wisdom cube, but a more special and powerful one... One, which calls itself...

Alterium.
