Azur Lane: Thetean Might! (On hold)

This alternate world of Azur Lane is one where, on top of Eagle Union, there is another faction called Northern Union. They are the only faction in Azur Lane which has succeeded in creating male Kansen, and aren't willing to share the secret with other factions, as male kansen don't have the same problems as females do, and they want to be the only ones with that advantage. Though they do help Azur Lane, as in this book.
