Isunna

There is an insidious sea spirit in Japanese folklore. If you look at her from the front, you can see a woman, although the lower part of her body is blurry, and if from behind, then a rock. She likes to appear before the ship or boat goes out to sea, approach the sailors and ask them to lend her a scoop. If someone fulfills her request, she immediately starts pouring water into the ship or boat until the ship slowly sank to the bottom.
