Fics like Malachite Flames

A threat to mankind lurks in the waters of the pacific, encroaching ever closer to Japan. The world, however, knows that they will not stop there. They must band together, to survive the coming war, or they will all fall together. The Azur Lane program, spearheaded by Principal Nezu of UA, is the first of these efforts. Midoriya Izuku has been chosen. He resonates with one of the Wisdom Cubes, attuned to one of the greatest ships of her era. He is to become the vessel for it's newly acquired power, and to be the way in which she can once again fight on the seas. He won't be alone for long, however, as slowly, more and more will resonate with a ship under Azur Lane's control. And eventually, they might have enough to begin making a real effort to push back the Sirens. It won't be easy, however. These ships come from different origins, but all the same era, and they have history. Bloody, and brutal history. Killing allies, sisters, and even each other. Now that they have been given a new life, a new purpose, can they put their past behind them? Or will they be consumed by the war many of them never left alive, centuries long over? Note: Knowledge of Azur Lane is not necessary to understand this story
