Disclaimer: I've noticed the absolute lack of any Seto no Hayanome crossovers, and I wanted to do one for Hetalia. Of course that means that I once again own nothing as that honor belongs to Hidekazu Himaryura, Tahiko Kimura, Studios Gonzo, AIC, and Deen, and last of all Funimation entertainment. Please read and review.

One random day, Japanese intelligence picked up something rather strange...

Japan stood outside of the Emperor's palace in Tokyo, he had received an urgent call from his boss early that morning about something rather strange that had been picked up within his country. "This better be something good." he thought. Pochi-kun had decided to come with him and despite how groggy he was at being woken up so early, he still followed him into the secret confines of the palace where his country's intelligence operated.

"日本歓迎" his boss said when he entered. "We have something of interest for you."

"はい, you stated that when you woke me up this morning."

"Right, now down to business, we have received footage from a security camera from a village off the Seto Inland Sea located on Honshu." As he said this he played the footage of a carnival and a young couple passing by a water tank. The boy was an average sort who wore Western style summer clothing, he had one cowlick which stood up from his black hair.

"Reminds me somewhat of America-san" Japan thought to himself as he continued to watch this ordinary clip. The girl he noticed was wearing a Japanese Yokata and was as pale and as beautiful as the moon, her hair went down to her middle back and was a tan color. "You got me to come here this early just to see this!" Japan said clearly not trying to hide the irritation in his voice. "Maybe we're overpaying this department."

"忍耐 Nihon" his boss reassured, "You still haven't seen the whole clip. All of a sudden, the girl tripped over the water tank and, as his boss slowed the clip, he watched in astonishment as the water hit her legs. The legs then fused together and formed a pink tail. A PINK TAIL!

"マサカ" Japan muttered as he watched this drama unfold before his very eyes. He regained his composure after a few seconds. "This could be a hoax." he said, trying to fight this "illusion"as he saw saw it.

"It isn't" his boss said with sincerity. "We've been investigating this for the last few days and have found that the girl, registered at the local school as San Seto doesn't have any property on the mainland. The boy, Saitama resident Michishio Nagasumi was reportedly spotted by other tourists drowning in the bay and was assumed dead until he turned up later that day with absolutely no explanation. The two have been spending the last few days of Nagasumi's vacation together with absolutely no explanation, and at the end of the summer, San Seto's name turned up on a train ticket back to Saitama, and it was coupled with that of the Michishio family."

"Then this means..."

"Yes, 人魚 exist in the world"
