Your name is Orochi and you were a giant battleship with a soul created with the help of the Sirens by the Sakura Empire, but during your great first battle when you fought on the side of the Sirens, the Ship Girls from the Sakura Empire as well as the Ship Girls from Iron Blood when they realized that they were deceived by the Sirens turned away from the Sirens and joined the Ship Girls from Azure Lane in the war against the Sirens.
You as the battleship Orochi during this battle were finally sunk by the united forces of all the Ship girls factions, but your soul survived and recreated your human body that you once had before the Sirens made you the battleship Orochi.
For some time you were on a deserted island until one group of Ship Girl from Sakura Empire under the leadership of IJN Atago accidentally found you and captured you when they realized that you were the living incarnation of battleship Orochi, exhausted and depressed you did not resist.
You are currently completely naked and chained by your wrists, ankles and neck to the wall of a small cell in the dungeon under IJN Nagato's palace in Sakura Empire for several days, suddenly you hear footsteps in the distance and after a moment IJN Nagato approaches the bars of your cell and sits on the chair opposite looking at you with sadistic satisfaction, then she starts mocking and teasing you:
Hello my dear Orochi, my beautiful slaveman, hehe... How are you today? Ara~ Ara~ You probably don't feel comfortable in these chains, don't you? Ohh... Poor thing... HAHA!
