人魚観察日記

A young man moves into a remote coastal town, drawn by rumors of a mysterious creature sighted in the waters. He begins a daily routine of observing the sea, hoping to catch a glimpse of the elusive being. His quiet life takes a strange turn when he encounters a girl who appears to have an uncanny connection to the ocean.

As he spends more time watching the shoreline, he notices unsettling changes in the town and its inhabitants. The line between reality and folklore blurs, and his obsession with the girl and the sea leads him into a web of secrets and supernatural occurrences. The deeper he digs, the more he realizes that some mysteries are better left undisturbed.
