【作業用BGM】海中遺跡と波歩きの魔女｜穏やかな海辺のファンタジーBGM

Walk peacefully across a crystal-clear cobalt blue sea with a gentle sea-walking witch. Beneath the sparkling surface rests a forgotten ancient city where colorful fish, sea turtles, and coral quietly thrive. Warm sunlight dances across the waves as every step becomes part of the calmest seaside journey in a magical fantasy world. Perfect for working, studying, reading, drawing, relaxing, creative focus, or winding down before sleep.
