Synopsis

Tatsumi stumbles across a collapsed man by a lake on his way home from school—except it turns out to be Wakasa, a merman. Since pollution has made Wakasa's underwater home uninhabitable, Tatsumi lets him crash in his bathtub. That's when things get weird. Wakasa's loud and chaotic, and his friends—Takasu, Mikuni, and Maki—keep dropping by unannounced, turning Tatsumi's life upside down. The high schooler finds himself caught between trying to maintain some semblance of a normal routine and getting pulled into their antics. He doesn't hate it, honestly, but keeping up with a houseful of curious merfolk while juggling school and everything else? That's easier said than done.
