In *Like a Dragon: Pirate Yakuza in Hawaii*, Goro Majima showcases his versatility with two unique fighting styles. One of them, the "Sea Dog" pirate style, boasts four powerful finishers perfect for taking on large crowds. However, securing all the dark instruments in the game is a challenging journey.
How to Obtain the Dark God's Violin in Pirate Yakuza

The Dark God's Violin is your first Dark Instrument to unlock in *Pirate Yakuza* and is essential for progressing through the main storyline. You'll encounter this quest in Chapter 2, where your crewmate Jason directs you to meet an old friend. This leads Goro and his crew to clash with the Devil Flag pirates, who have murdered Jason's friend and stolen the precious Pharoh Stone.
After the encounter, you'll meet Misaki, the orphaned daughter of the slain friend, who joins the Goro Pirates seeking vengeance. Following the questline will lead you to the islands east of Madlantis, where you'll face a formidable fleet of Devil Flag pirates. Focus your efforts on the boss ship to board it and continue the fight. Upon defeating the Devil Flags, you'll claim the Dark God's Violin, which you can immediately test in a thrilling 100-enemy brawl on the island.
After the battle, a cutscene introduces the fleet's captains—Yakuza, Ronin, Shinobi, and Zeus. They challenge the Goro Pirates, setting off the side quest to collect all the Dark Instruments. While not necessary for the main story, defeating the Devil Flags is crucial if you want to gather all the Dark Instruments.

Following the initial boss ship defeat and the 100-enemy brawl, you'll start seeing Devil Flag markers on the waters. Defeating these ships will earn you Devil Flags, and you'll need 70 of them to unlock the next step. Engage any Devil Flag ships or treasure islands you come across to accumulate flags quickly.
Once you have 70 flags, Atali Island will appear on your map. Prepare a strong landing party as you'll face multiple waves of attackers. After navigating through the island's challenges, you'll confront Devil Flag Captain Yakuza. Defeating him grants you access to the treasure chest containing the Dark God's Ocarina.

After obtaining the Ocarina, you'll follow a series of cutscenes and new objectives. Captain Yakuza tricks you into a location where you'll face another 100-enemy brawl. Use your newly acquired Ocarina to clear the mob.
You'll then learn that Zeus is headed to Flame Island. To proceed, you need a three-star ranking and 130 Devil Flags. Keep attacking Devil Flag ships as you sail to gather the required flags. Once you have them, head to the Flame Entrance Lighthouse to trigger a cutscene, leading you to conquer four treasure islands: Sunset, Heatwave, Welldone, and Scorching Heat. These islands don't allow health item consumption during battle, so ensure your crew is well-prepared.
After navigating the treasure islands, another fleet battle awaits. Focus on the boss ship, board it, and defeat the first mate to land on Flame Island. Choose Jason, Masaru, Minami, and Saejima for your landing party. After smaller battles, you'll face Captain Ronin. Use your Dark Instruments to defeat him and access the treasure chest holding the Dark God of the Earth's Guitar.

The Dark God's Saxophone is the final Dark Instrument you'll need, requiring a Pirate Rank Four. Achieve this by completing main story missions, recruiting new crew members, and engaging in mini-games and side quests. You'll also need to collect at least 220 Devil Flags.
Sail to the Frost Entrance Lighthouse to trigger a cutscene and engage the Devil Flag's Fleet. Conquer four additional islands—Snowview, Coldwave, Icicle Island, and Glacial—to gather more Devil Flags. Defeat Captain Shinobi's First Fleet before landing on Frost Island, where you'll face multiple battles leading to a cave and a recovery area.
The final battle on Frost Island pits you against Captain Shinobi. After defeating him, a cutscene reveals Zeus taking Misaki hostage, ending with Goro obtaining the Dark God's Saxophone. The ultimate challenge awaits with Zeus, a two-stage battle to rescue Misaki, which, while not necessary for collecting the Dark Instruments, concludes the saga against the Devil Flags.
