The Unyielding Dreadnought (An Azur Lane tale)

Salt water, the creaking of steel and thunder, it's all you know as home. You didn't have a name, but a designation: X10N-P. You were a prototype of what was to be the next generation of Dreadnought's, yet the Locker took you down before you could even try. It was to be your end, to be sunk at the bottom of the Mariana Trench.........

Until a little blue cube dropped on you, awaking a demon inside. A demon that will make the seven seas fear your name.....
