How I Rebuilt Azur Lane in Another World

After transmigrating with his port to a parallel world's steampunk Victorian era, Li Xiao wakes up to discover that this world has Sirens, shipgirls, and even octopus girls, but no Azur Lane. The shipgirls face widespread discrimination and have left their homes, while humanity continues to lose territory to the Siren attacks. To protect his girls and the shipgirls of this world, Li Xiao decides to rebuild Azur Lane and win his girls a stretch of sea where they can live in the sunlight.
