Muromi-san

Mukoujima Takurou is a solitary teen who passes his days fishing off the pier. One day, to his astonishment, he reels in Muromi-a mermaid who doesn’t even know she’s a mermaid until Takurou points it out. She’s clueless, erratic, and has a serious fondness for alcohol. From then on, whenever Takurou casts his line, Muromi shows up, turning his quiet routine upside down with her antics.
