Kaen Daiko, also known as Kaioen Mode for the Dragon fruit, is one of the most time-consuming upgrades in Ultimate Pirate Piece. It’s not something you unlock quickly, and most players get stuck halfway because of unclear requirements or missing materials. If you’re aiming for one of the strongest Dragon upgrades, you’ll need patience and a clear plan. This guide walks through everything you need—from materials to every trial—so you can unlock Kaen Daiko without wasting time or resources.
Where to Start Kaen Daiko Quest & How to Unlock
Before anything else, you need to head to Water 7, which is where the Kaen Daiko progression begins. This area acts as the main hub for advanced upgrades, so make sure you’re properly geared before going there.
Once you arrive, you’ll be interacting with Kaido-related progression, and from here, the real grind begins. You won’t be able to start unless you already have the Dragon fruit equipped, so make sure you have that ready beforehand.
Before unlocking the trials, you must prepare the required materials. These are not optional, and farming them early will save you a lot of backtracking later.
- 4 Dragon Fruits You’ll need multiple copies of the same fruit, which means relying on spins or boss drops. This can take time due to RNG, so it’s better to start collecting early instead of waiting until later stages.
- 8 Dragon Scales These are typically obtained from Dragon-related enemies or bosses. Farming the Dragon Boss repeatedly is usually the most consistent method, especially since you’ll need to fight it anyway for later trials.
Getting these materials done first is important because once you start the trials, you don’t want to pause just to farm missing items.
All Kaen Daiko Trial Quests Explained
After preparing the materials, you’ll unlock a series of five trials. Each one builds on the previous, and all of them require you to use the Dragon fruit actively.
- Trial I: Defeat Every Island Boss (Dragon Equipped)
This trial requires you to go across all islands and defeat their bosses while using Dragon. It’s not difficult, but it takes time due to travel and boss respawns. Make sure you don’t switch your fruit during this step or it won’t count. - Trial II: Defeat Dragon Boss 20 Times
This is where the grind begins. You’ll need to repeatedly farm the Dragon Boss until you hit 20 kills. It’s recommended to server hop or farm with friends to speed things up. - Trial III: Get a Dragon Fruit Drop from Dragon Boss
This step depends on luck. Even if you’ve already defeated the boss many times, you must get a fresh Dragon Fruit drop during this trial. Just keep farming—the drop will eventually happen. - Trial IV: Eat 5 Dragon Fruits
You’ll need to consume five Dragon fruits, meaning you must collect extras beyond your original one. This is why saving fruits early is very helpful. - Trial V: Return with 200,000 Ancient Coins
The final step is a resource check. You need a large amount of Ancient Coins, which are usually obtained from bosses, raids, or high-level farming. If you haven’t been saving, this part can take the longest.
Tips to Complete Kaen Daiko Faster
Progressing through Kaen Daiko can feel overwhelming, but a few simple strategies can make it much smoother.
- Farm Dragon Boss Early and Often Since multiple trials involve the same boss, it’s efficient to start farming it as soon as possible. You’ll collect scales, possible fruit drops, and progress toward Trial II at the same time.
- Don’t Waste Extra Dragon Fruits Always store extra Dragon fruits instead of ignoring them. You’ll need at least five for Trial IV, and getting them later can slow you down.
- Save Ancient Coins From the Start Many players get stuck at the last trial because they didn’t prepare. Start saving Ancient Coins early so you don’t hit a wall at the end.
- Stick With Dragon During Trials Every trial requires Dragon to be equipped. Switching to another fruit can reset or block your progress, so avoid changing builds during this process.
Kaen Daiko (Kaioen Mode – Dragon) is not just a simple upgrade—it’s a full progression path that tests both your patience and preparation. From farming rare drops to completing multiple boss challenges, every step requires consistency.
If you approach it step by step—collecting materials early, farming efficiently, and staying focused on the trials—you’ll eventually unlock one of the strongest Dragon upgrades in the game. Once completed, all the effort pays off with a noticeable boost in power and performance.
