Chapter 2 introduces Honolulu and Madlantis, the game's main hubs. Exploring these locations and recruiting crew members is key to upgrading your ship and advancing the story. The main questline leads you to Julie, a mechanic who runs GearWorks in Honolulu. She upgrades the Goromaru and subsequently allows you to upgrade its cannons.
Different upgrades require various materials obtained by defeating enemies. These include:

Visit Julie, select the cannon you wish to upgrade, and equip the upgraded cannons via your ship's crew formation menu.

The Shark Cannon offers elemental damage and a faster reload than other options, but its damage output is lower. Consider this a later-game purchase, primarily useful for recruiting Julie.

The Egesta Cannon delivers slow but steady damage, making it a strategic choice, especially since you can equip different cannons on each side of the Goromaru. Its two-round firing compensates for its slower reload.

The Laser Cannon is arguably the best weapon in the game. Save your components for this devastating upgrade; its high damage output more than makes up for its long reload time.

The Super Laser Cannon is the ultimate Goromaru upgrade, boasting incredible power and long-range capabilities. However, it requires rare components, making it a late-game acquisition, ideal for challenging battles in the Pirate Coliseum and against Devil Pirates.
