Where Stray Dogs Swim (BSD Mer!AU)

Yokohama is famous for many things. One of those things in particular is the population of Merfolk. Little is know about these individuals from the sea. Some dwell amongst people, others stay lurking in the depths. Most think they are a myth.

Atsushi discovers that he is one of these creatures when he is pushed overboard off of a ship. He thinks he is done for, only to end up on a sandy beach in Yokohama. He is met by another merfolk by the name of Dazai who offers him a place to stay, as well as a means to make money. Atsushi is hesitant at first but eventually agrees and joins the Aquatic Detective Agency. What the hell has he gotten himself into.

Author's Note(s): This fan fiction is mainly going to focus on the story line and how it impacts the characters. There are going to be a few ships in here but they wont be expanded on unless they are important to the story. This story does NOT contain Soukou or any of it's variants (shin soukou or old soukou). Expect a LOT of name changes to fit the theme lol. Hope you enjoy :3 (Cover art done by me. Characters and the original story belong to Kafka Asagiri. The only thing I own is the cover art, My OC(Kuniko Mukoda),and the AU.)
