The 'Fire Chief Constantine' is a fireboat built by NAVINCO industries and serving at the Self-Defense Fire Brigade, a fire brigade tasked with guarding industrial areas near the coast. The ship has been in service for over twelve years and has become old. Finally, the commander of the brigade decides to retire the vessel and scuttle it. While en route to its resting place, an electromagnetic geostorm manifests at the harbor and the fireboat disappears only to reappear in an alternate WW2 universe wehre warships can take the form of young girls. Now stuck in this world, Fire Chief Constantine decides to reside there, acting as Azur Lane's only fireboat while also fighting against the alien forces known as 'The Sirens'. Will FC Constantine manage to survive the war and find a peaceful life on the oceans of this new world? This is a fanfic I'm writing to celebrate my success in joining the fire service in my country. I hope you enjoy.
