Merman in My Tub

What happens when a creature from the sea decides to take over your bathtub? Tatsumi, a cool and reserved teenage boy, suddenly finds himself sharing his small Tokyo apartment with Wakasa, a playful and self-absorbed merman. As these two very different young men navigate their daily lives under one roof, they must figure out how to get along. Making matters even more complicated are the surprise visits from Wakasa's ocean friends—an anthropomorphized octopus, jellyfish, and hermit crab. Welcome to Tatsumi's bathtub, where things are getting rather crowded.
