Mizukawa loves to travel explore around the world by swimming across the oceans.
Monica and her family had a vacation trip and they rented a cottage or some hut or cabin near a beach in Mexico when Monica was about 2 or 3 years old and when her mom was still alive.
During sunset when Monica was checking out some fancy seashells, she saw a Japanese Mermaid/Ningyo swimming around at the ocean. Monica was awestruck to see a real mermaid like this before.
