The Dark God's Violin is the first, and story-essential, Dark Instrument. Unlocked during Chapter 2, a crew member (Jason) leads you to a meeting with an old friend. This encounter introduces the Devil Flag pirates, who've killed Jason's friend and stolen the Pharaoh Stone. You'll meet Misaki, the friend's daughter, who joins your crew seeking revenge, initiating the side quest.
Following the questline leads you to islands east of Madlantis. A challenging battle against a stronger Devil Flag fleet awaits; focus your attacks on the boss ship to board it. Victory yields the Dark God's Violin. The game then lets you test it in a 100-enemy brawl. Defeating the Devil Flags triggers a cutscene introducing the fleet captains: Yakuza, Ronin, Shinobi, and Zeus, who challenge you, officially beginning the side quest. Note: Defeating the Devil Flags is optional for the main story, but necessary for all Dark Instruments.

After the initial brawl, Devil Flag markers appear on your map. Defeating Devil Flag ships earns you Devil Flags; 70 are needed for the next instrument. Atali Island unlocks, requiring a strong landing party. Multiple enemy waves precede a treasure chest containing the Dark God's Ocarina, but you must defeat Devil Flag Captain Yakuza first.

Defeating Captain Yakuza triggers cutscenes and new objectives, leading to a supposed location of the Pharaoh Stone—a ruse resulting in another 100-enemy fight. You’ll then learn Zeus is headed to Flame Island. This stage requires at least a three-star ranking and 130 Devil Flags. Sail to the Flame Entrance Lighthouse, triggering a cutscene and access to four treasure islands (Sunset, Heatwave, Welldone, and Scorching Heat) to conquer. Remember, health items are unavailable on treasure islands. After conquering these islands and a subsequent fleet battle, a final battle against Captain Ronin on Flame Island grants you the Dark God of the Earth's Guitar.

A Pirate Rank Four and 220 Devil Flags are required for the final Dark Instrument. Sailing to the Frost Entrance Lighthouse initiates a fight with the Devil Flag fleet blocking Frost Island. Four more islands (Snowview, Coldwave, Icicle Island, and Glacial) offer more Devil Flags and battles. Defeat Captain Shinobi's first fleet before landing. The island features battles leading to a cave and a recovery area before the final boss fight against Captain Shinobi. After defeating him, a cutscene with Zeus leads to the final Dark Instrument. A final, challenging two-stage battle against Zeus to rescue Misaki follows, though not required to obtain all four Dark Instruments.
