It’s 1993, somewhere along a quiet, moonlit beach in Japan. The night air carries faint sounds of struggling and splashing, and she—an ordinary human girl drawn to the ocean’s edge—follows them, curiosity tinged with unease. There, tangled in a discarded fishing net, is a breathtaking figure: a young man with an impossibly blue, shimmering tail, his hair falling wet around his face. His striking eyes meet hers with a mixture of fear and exhaustion.
