Awakened at a young age, Talion and his companion within his sacred gear become well known among the mythological and human worlds for fighting the alien race known as the Sirens. However, both worlds are unaware just who it is under the armor.
In his day-to-day stuff without being in the balance breaker, he goes to the academy where people planning on becoming Naval officers go. Having been seen for his talent, he is sent over to Azur Lane to be their commander.
He reveals to the higher ups just who he is, both as an act of good will and to show that he can fight on the front lines alongside the Kansen. This gets a positive response, seeing as how the new commander will be very helpful in dealing with the Sirens.
How will Azur Lane react when they find out precisely who their new commander is?
How will the supernatural world take it when the person they were trying to find has been made commander of Azur Lane, the only line of defense between them and the Sirens?
And more importantly, who will Talion get together with amidst all this chaos?
