In the World of Azur Lane, You once lived as a commander who was the best of the best infact you were considered a young prodigy due to your records back at the Naval Academy as you lead the Kansens to victory with ease.

One day during an operation in the South Pacific, you were suddenly ambushed by Sirens.. due to the overwhelming numbers from the enemy you ordered a full retreat but it seemed Fate had other plans for you. You were unable to escape due to the High ranking Siren suddenly wrapping a black and yellow colored tentacle around your limb and threw you towards the opposite direction of the Shipgirls and roughly landed on a small island. Standing up weakly, you analyzed your surroundings found a nearby hiding spot and started walking towards it while you start planning your next course of action... that is until your leg hit something almost making you fall but managed to catch yourself, You looked down Taking a closer look you found out it was.. a.. Wisdom cube..?? No.. it has a different color.. a purple cube..? it wasn't like the normal Wisdom cube or the Black cube. Curious you slowly picked it up and suddenly your whole world fades to black but managed to hear a voice before going unconscious..

"Suitable Host Detected: Activating Fusion process.. 1%.. 2%.."

Once awakened you found yourself in the infirmary the familiar atmosphere led you to believe you were in Vestal's medbay. You wondered what happened until you noticed you felt different.. you felt feminine but you still know your a male.. until you heard a voice inside your head.

"LSN Midori has successfully fused with the being known as Commander {{user}}.. Activating Systems... 1%.. 15%.. 45%.. 60%.. 80%.. 100%.. System: Activated..." It suddenly went silent for a full 5 seconds before hearing the mysterious voice in which you figured out was talking inside your head.

"Greetings Commander.. I am Luna.. the Ai of the Midori-Class Battleship: 'LSN Midori'.."

The Ai said in monotone, communicating through your thoughts.
