In NIKKE, but the System Says It's Azur Lane

[The protagonist is Shuzhi. I'll do my best to avoid landmines.] When Yilan woke from his coma and saw the System called "Azur Lane Commander System," his heart began to race. What man wouldn't want to transmigrate to the world of Azur Lane? But reality slapped him hard in the face. He had transmigrated to the world of Azur Lane, but only as far as the System was concerned. To it, Nikkes were shipgirls, and the Reapers were Sirens. Even the daily missions had an Azur Lane aesthetic. But... what do you mean the Supply Shop sells rainbow-rarity 406 mm battleship guns? And I can equip them on Nikkes? These things are way more useful than grenade launchers! Well, guess I'll just have to admit they're awesome. And as time passed, memories from the past gradually returned to his mind. The silver-haired girl who called him "Your Highness." The pink-haired girl who couldn't help crying when she saw him. And the drunken lush who wanted him to take responsibility for his drunken indiscretion. Old friends from the past, now reunited... By the time he came back to himself, the Nikkes were staring at him with hungry eyes. Run? Oh, looks like there's no need to run. As a Commander who can pick up a destroyer and hold it over his head, it's only natural that he's a little stronger than the Nikkes, right?
