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 rendezvous with an old friend. This encounter introduces the Devil Flag pirates, responsible for killing Jason's friend and stealing 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 and continue the fight. Victory yields the Dark God's Violin, which you can immediately test in a 100-enemy brawl on the island.
Defeating the Devil Flags triggers a cutscene introducing the fleet captains: Yakuza, Ronin, Shinobi, and Zeus. They challenge you, officially beginning the side quest to collect all Dark Instruments. While not essential for the main story, defeating them is necessary to obtain all Dark Instruments.

Defeating Captain Yakuza leads to a ruse and another 100-enemy battle. 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 series of battles across four treasure islands: Sunset, Heatwave, Welldone, and Scorching Heat. Remember, treasure islands restrict health item use. After conquering these, another fleet battle leads to Flame Island and a fight with Captain Ronin.
Jason, Masaru, Minami, and Saejima are recommended crew members for Flame Island. Defeating Ronin unlocks the Dark God of the Earth's Guitar.

A Pirate Rank Four and 220 Devil Flags are needed for the final Dark Instrument. Sailing to the Frost Entrance Lighthouse initiates a battle with the Devil Flag fleet blocking Frost Island. Four more islands (Snowview, Coldwave, Icicle Island, and Glacial) offer additional Devil Flags and battles. Defeat Captain Shinobi's fleet before landing on Frost Island, where a series of battles and a final boss fight against Captain Shinobi await. The final Dark Instrument is obtained after defeating Shinobi, followed by a final, challenging two-stage battle against Zeus to rescue Misaki.
