Jotaro was out at sea, studying the local jellyfish population instead of enjoying the warm, pleasant sunny day. The waters were calm, too, so the boat didn't rock as much. There has been an increase of Nomura's jellyfish near the coast of Japan, and he had to study what was causing the sudden population increase.
Jotaro reeled the net in, catching some of the jellyfish he was researching and other sea life.
"Let me go!" he heard a voice from the net.
"Hello?" Jotaro called out. "Are you in the net?"
"Where else would I be?"
"Don't tell me you came from the sea," he replied.
"Of course, I came from the sea. Now can you place me back?"
"Hold on. I can release my catch. I need to put it in the boat. I'll put you back in the water as soon as possible."
Jotaro controlled the crane, placing the net gently on the deck. There was a pile of jellyfish, some other fish, and a—and Jotaro could not believe this—mermaid, a handsome one too. He was a redhead and had dark blue eyes.
"Wow," the mermaid said, blushing at him. "I mean, are you going to let me go?"
"Sure, let me put on my gloves so I can move the other fish around."
"Could you also throw the other species back into the ocean? I have been seeing fewer of these types of fish swimming around." The redhead pointed at the bluefin tuna and swordfish.
"Sure, just those?" Jotaro needed to name what species of fish he caught along with the jellyfish.
"Yes."
The two of them tossed out the overfished fish species.
"So," Jotaro spoke first, "who are you?"
"Noriaki Kakyoin. And you are?"
"Jotaro Kujo. Why were you near my boat?"
"I wanted to know humans a bit more. Others of my kind say they're cruel and hideous, but you're handsome." He noticed Jotaro blushed despite his neutral expression. "And you seem nice. You threw the endangered fish into the water."
"Do you want to go back into the water?"
"Sure."
Jotaro moved the jellyfish aside and carried Kakyoin.
"Wow, you're strong," Kakyoin commented.
"And you're surprisingly light."
Jotaro was about to throw him into the water.
"Wait!" Kakyoin said. The question he was going to ask made him blush. "Do you want to kiss before we go?"
"In stories, isn't the mermaid supposed to seduce the human?"
"Is that a no?"
Jotaro kissed his lips briefly. When he withdrew his lips, Kakyoin's face was red.
"I don't want to leave you!" the mermaid said.
"Don't you need to be in the water?"
"Yeah, but will we see each other again?"
"I'm a marine biologist. Yeah, we'll see each other again."
Jotaro tossed him into the water.
"I'll miss you!" Kakyoin said.
"We'll see each other tomorrow. I have to check on the spider crabs."
The marine biologist sailed away, and Kakyoin swam deep into the sea.
