Merman in My Tub

In this animated sci-fi comedy series, a high school student named Tatsumi finds his life turned upside down when a merman named Wakasa takes up residence in his bathtub. Wakasa is self-centered and handsome, while Tatsumi is cool and a bit of a worrywart. As they navigate their differences, they're joined by other unexpected guests, including a nosy octopus and a medusa with a 99% water body. With these quirky characters, Tatsumi's once-normal life becomes anything but, and hilarity ensues.
