Right before the disruption of the Sakura Empire and Iron Blood from Azur Lane, one of the Sakura Empire submarines was sent on a mission, alone, that anyone would think that it's Impossible, but this submarine didn't think so...
The I-400 Submarine heard these exact words from the Shrine Maiden, Nagato:
"Submarine Carrier I-400, you have the orders to sail around the globe to exterminate every enemy ship you see. As things are going now, it might seems that Azur Lane and Iron Blood will disrupt our alliance with each other, for now you will be restricted to only sink Siren Ships, from there on, await new orders from me, my sister, Amagi, Akagi or Kaga. Understood?"
"Yes. Understood, My Lady."
