Shipgirls: Donghuang Never Falls

The year is 1800 on Blue Star, in a parallel timeline. The Qing Dynasty of the Donghuang Empire is basking in the fading afterglow of its so-called golden age. Hundreds of daimyo across the Shenying Islands are still sharpening their blades as they set their sights on Heian-kyo, while the Iris of Taixi is writing a tale of invincibility under the command of Napoleon...

To Ningyuan, flagship of the Donghuang fleet in the waters north of Australia, everything here seems much the same as it was in the main timeline at this point in history, until she encounters a group of monsters known as the "Deep Sea"...

Timeline: 1800 AD on a Blue Star where shipgirls were introduced in 1644 AD.

P.S. All of the protagonist's government reforms draw inspiration from dynasties before the Qing, with the main structure modeled on the Da Shun. Any similarities to the Red Revolution are purely coincidental.
