The Saga of the Seaside Inn is one of the most extensive and engaging side quests in Final Fantasy VII Rebirth. Starting in Chapter 7 in Costa del Sol, players are tasked with helping Johnny restore his rundown resort. By navigating through multiple regions and completing diverse tasks, players can fully restore the establishment and access unique gameplay features.

Starting the Quest and Gathering Materials

To initiate this journey, head to the noticeboard in Costa del Sol or speak directly with Johnny at his hotel. Your first major objective requires retrieving lost refurbishment materials scattered around zipline towers in the Corel region. Locating at least four bundle materials moves the quest forward, though gathering all eight provides the best outcome.

Crafting the Boiler Valve

After delivering the materials, Johnny requests aid at a nearby Republic-Era factory. Using a Chocobo to sniff out a hidden Transmuter Chip in the area allows you to unlock the necessary crafting recipe. Once you acquire Iron Ore, Zinc Ore, and Amethysts, you can craft the Boiler Valve and hand it over to continue.

Stealing the Tonberry King Crown

The final phase of the quest takes place after reaching Chapter 9, where you must confront the Tonberry King. During combat, pressuring the boss forces it to drop its crown, which you can steal using the Steal Materia before defeating the enemy. Delivering the Pristine Crown back to Johnny brings the lengthy questline to a successful conclusion.

Unlocking Hidden Trove Rewards

Completing this side quest grants valuable party experience, improves your relationship with Yuffie, and unlocks a special Queen's Blood card. Most importantly, it opens up Johnny's Treasure Trove, allowing players to display collectibles gathered throughout their adventure. Collecting all items in the trove rewards completionists with exclusive achievements and special display honors.
