A British light cruiser added as part of a collaboration between Azur Lane and World of Warships, based off of a conceptual design meant to succeed the Town-class cruisers already in use by the Royal Navy. Improvements over her predecessors included a dual-purpose main battery consisting of 12 6" guns and an increased torpedo armament. The design was abandoned and no ship was ever laid down. Post-war budget cuts pretty much doomed the project, shifting priority towards newer design with rapid firing 152mm dual-purpose gun (which ultimately was also cancelled).
Neptune is portrayed as a bluenettemaid, her hair done into twin pigtails. She wields a trident, a reference to her namesake, the ancient Roman god of the seas.
In reference to her World of Warships counterpart, Neptune receives improved AP shells and a powerful heal.
