Authentic Triple Katana is a sword that can be obtained in the New World by killing a Sea King. The drop chance from a chest after having defeated a Sea King is dependent on the rarity of the chest, with the highest rarity being a tier 3 chest The drop rate is very low, making it a difficult sword to obtain1. It is considered one of the best swords in the game alongside Dark Blade and Hell Sword, as it has the highest damage for a sword and an excellent Kenbunshoku Haki breaker1[]

After you defeat him, you will obtain a Diverse Sphere. You will need to use this sphere to light a fire in one of the colosseum pillars.
Next, go to Cake Island and talk to an NPC in the cafe. You will be tasked to kill the dragon boss. You will get another diverse sphere, and you can light a fireplace beside a brown roofed house next to an arch bridge in the Island of Fiore.
Lastly, go to Shred Endangering and talk to an NPC that is hidden inside a grey pillar you can go through at the back of the spawn building of the island. Summon the Lucidus boss and kill him with the m1 of your Authentic Triple Katana on your last hit and he will drop to light another diverse sphere. Use the diverse sphere on the fireplace on top of a building near the Devastate (3725) quest giver (You can see the fireplace from the quest giver).
Then, head to the arch bridge near it and you can find an NPC on top of the arch. He will tell you to find someone named ‘Walter’.

The Authentic Triple Katana has a base swing that deals 5,001 damage with Busoshoku Haki and 4,751 damage without Haki.
It also has a unique attribute of having a sub-special that happens every 4 swings. Every 4 swings, a small blue tornado is summoned and damages anything that touches it. This tornado is created after 4 consecutive swings, with there being no limit to how many tornadoes the player can create.
This tornado is created from the player’s body and lasts for 3 seconds. The tornado hits 3 times, each hit dealing 3,000 damage with a total of 9,000 damage. The damage of the tornado remains the same regardless of whether Busoshoku Haki is activated. The player is not stunned or interrupted mid-swing by the creation of the tornado, so it does not hinder the user’s performance in any way .
