Chapter 1 — Traces of the Sea People

First Real DiveMain
Dive into the Blue Hole properly for the first time. Catch fish, explore the shallows (0-50m), and serve your first real sushi menu.
Focus on catching Tuna and Mackerel — they sell well and make simple but profitable dishes.

Always accept his photo requests — completing them unlocks new areas.

Discover the Sea People, descendants of an ancient deep-sea civilization. Navigate the mid-depths (130-250m) and learn their story.
Upgrade your oxygen tank before this chapter — you will need the extra time underwater.
Unlock Duff's Weapon ShopMain
Duff sets up a proper weapon shop. Now you can craft multiple weapon types including the Net Gun and Tranq Dart.
Craft the Net Gun first — it captures small fish without damaging them, yielding higher-grade ingredients.

Keep high-quality fish in stock for VIPs — they pay premium prices.
The Giant SquidMain

The Deep Zone has aggressive predators — be ready to fight or flee.
Staff Hiring UnlockedSide

Hire a wasabi refiller first, then a drink server — these two roles save the most time.

Max out your oxygen and harpoon before heading into the abyss. This is the most dangerous area yet.
The Great White Shark (Klaus)Main
Face Klaus, the legendary Great White Shark that terrorizes the deep. This is one of the toughest battles in the game.
Use the Sniper Rifle for precision damage. Stay mobile and watch for its charge attack pattern.

Prioritize the kitchen upgrade — faster cooking means more dishes served per night.
