These swords are integral to the lore of One Piece and represent the skills, strength, and heritage of the characters who wield them.

In One Piece, swords play an important role in the world of combat, and many characters use unique swords with great skill. There isn't an official "ranking" system for swords in the One Piece world, but swords can be categorized based on their rarity, quality, and the abilities they bestow upon their wielders. Below are some of the most notable swords in One Piece and their respective categories:

1. Great Swords (Grade of Quality)

Swords in One Piece are classified into three grades based on their quality and craftsmanship:

• Supreme Grade (Supreme Meito): The highest quality swords, often considered legendary. These swords are extremely rare, powerful, and have historical significance. They are considered treasures by swordsmiths and are wielded by only the strongest swordsmen.
• Example Swords:
• "Göring" (Goriburi): Wielded by Dracule Mihawk, the strongest swordsman in the world. It's an iconic black sword of Supreme Grade.
• "Ryouji Wato": Wielded by Roronoa Zoro when he gets a few rare special swords.
• It's used by **Hatchboy men we say about place

In One Piece, the question of what is the "best" sword is subjective and depends on factors like the strength of the wielder, the sword's abilities, and its historical significance. However, some swords are widely regarded as being the most powerful or legendary in the One Piece world.

1. Yoru (夜)

• Wielder: Dracule Mihawk
• Class: Supreme Grade Sword (Meito)
• Why it's the best: Yoru is often considered the strongest sword in the One Piece world. It is a massive black blade wielded by Dracule Mihawk, the world's greatest swordsman. Mihawk's immense skill with Yoru makes it an incredibly deadly weapon. Yoru is famous for its overwhelming cutting power and versatility, and Mihawk’s unmatched strength with it solidifies its status as the best sword in the series.

2. Enma (閻魔)

• Wielder: Roronoa Zoro (originally Kozuki Oden)
• Class: Great Grade Sword
• Why it's one of the best: Enma is one of the most powerful swords in One Piece and is considered a Great Grade Sword. The sword is renowned for its ability to draw out the user's Haki and test their strength. It once belonged to Kozuki Oden, and after Oden's death, it was passed down to Zoro. Enma is particularly significant because of its ability to "consume" Haki, making it dangerous if not wielded with enough control and strength. It plays a crucial role in Zoro's development as a swordsman and might eventually surpass many other swords, including Yoru, depending on Zoro’s growth.

3. Supreme Grade Swords (Meito) - Other Notable Swords

While Yoru and Enma are considered the top swords, other swords in the Supreme Grade Sword category also hold immense power, such as:

• Shusui (秋水): Wielded by Roronoa Zoro (originally Ryuma). It is a legendary black sword associated with the hero of Wano, Ryuma, and is highly revered.
• Sandai Kitetsu (三代鬼徹): A cursed sword that Zoro acquired. The Kitetsu series swords are all powerful but dangerous due to their curses. The Sandai Kitetsu is the most famous and feared of these.

4. The Sword of the Pirate King (Unnamed)

• Wielder: Gol D. Roger
• Why it's the best: Although not much is known about this sword, it is likely one of the Meito swords and considered extremely powerful, given that it belonged to Gol D. Roger, the Pirate King. Roger was an extraordinary swordsman, and his sword would have been among the finest in the world.

5. The Legendary Sword of the Dark Lord (Unnamed)

• Wielder: Mihawk
• Why it's the best: Mihawk’s sword is a mystery in terms of its name, but considering that Mihawk is the strongest swordsman, it's safe to say that his sword is one of the most powerful blades in existence.

6. Ame-no-Habakiri (天羽羽斬)

• Wielder: Kozuki Oden
• Why it's one of the best: Alongside Enma, Ame-no-Habakiri was one of Oden's legendary swords. It is also considered a Great Grade Sword and is said to be extremely powerful. Though it might not be as widely recognized as Yoru or Enma, it holds significant historical value.

7. Tatsu (竜)

• Wielder: Wano Samurai
• Why it's notable: A legendary sword, Tatsu, is said to belong to some of the most powerful warriors in Wano. It’s another blade known for its cutting abilities and historical significance.

Conclusion:

The best sword in One Piece is a matter of context. However, based on pure power and recognition:

• Yoru, wielded by Mihawk, is often considered the most powerful sword in the world.
• Enma, wielded by Zoro (and originally Oden), is another contender due to its unique abilities and the legacy behind it.
• Shusui, Sandai Kitetsu, and the sword of Gol D. Roger all carry significant weight in terms of power, history, and influence in the One Piece world.

Ultimately, the best sword could depend on the wielder and how well they can harness its power, and in the case of Zoro, it seems like the swords he uses are bound for greatness, with Enma and Yoru leading the way!

Yes, Zoro is indirectly related to Ryuma in One Piece. Ryuma was a legendary swordsman from Wano, and his sword, Shusui (秋水), was passed down to Zoro after his death. In addition to inheriting Shusui, Zoro is shown to have a significant connection to Ryuma's legacy when he is involved in a battle against a zombie version of Ryuma during the Thriller Bark arc.

Furthermore, Zoro's admiration for Ryuma is evident, as he considers Ryuma a legendary figure in the world of swordsmen. In terms of direct blood relation, there is no confirmation in the series that Zoro and Ryuma are blood relatives, but Zoro is connected to Ryuma through the sword and the legacy of swordsmanship.

As of the current point in One Piece, Zoro is not yet strong enough to defeat Mihawk, the world's greatest swordsman. Mihawk is an incredibly skilled swordsman who holds the title of "World's Strongest Swordsman," and his abilities far surpass those of Zoro at this stage of the story.

However, Zoro's ultimate goal is to become the world's greatest swordsman, and throughout the series, he has shown tremendous growth. Zoro trains relentlessly and has acquired powerful swords, like Enma, to improve his swordsmanship. He also continuously strives to surpass his limits, and his ambition is to challenge Mihawk someday to take the title of the strongest swordsman.

While Zoro has made great strides in becoming stronger, defeating Mihawk would likely be a future goal of his character, and it may happen once Zoro reaches his full potential. So, while Zoro is not currently at Mihawk's level, it's possible that in the future, after more training and development, he could eventually challenge and potentially defeat Mihawk.

In One Piece, Shanks wields a sword called Griffon. However, the exact grade of Shanks' sword has not been officially revealed in the series. Unlike other famous swords like Mihawk's Yoru or Zoro's Enma, the sword's grade is not specified, and it is not categorized as a "Meito" sword (the legendary swords of supreme, great, or great grade).

What is important about Shanks' sword is that it is a very powerful and highly revered blade, but its specific grade remains unknown. Despite not having an official grade, Griffon is symbolic of Shanks' mastery as a swordsman and his status as one of the most powerful pirates in the world.

It is also worth noting that Shanks is not often seen using his sword in combat, as he is known for his overall combat prowess, including his immense Haki abilities.

In One Piece, Trafalgar D. Water Law wields a sword called Kikoku. While the exact grade of Kikoku is not officially stated in the series, it is widely considered to be a great sword, which places it among the more powerful swords in the One Piece world, but not at the level of the Meito (legendary swords like Yoru, Enma, or Shusui).

Kikoku is a unique and powerful blade, known for its ability to amplify Law's Ope Ope no Mi (Op-Op Fruit) abilities. The sword has been crucial in many of Law's battles, especially because of its connection to his Devil Fruit powers, allowing him to manipulate the environment and enemies within his "Room."

While it may not be classified as a Supreme or Great Grade sword, Kikoku is undoubtedly a strong and significant weapon in the One Piece world.

In One Piece, Zoro has chosen three swords to become his Santoryu (Three-Sword Style) fighting style, which involves wielding one sword in each hand and one in his mouth. These swords are:

1. Wado Ichimonji – A legendary sword, originally belonging to his childhood friend Kuina, and a valuable part of Zoro's sword collection. It is a Meito sword, classified as a Great Grade sword, and one of the 21 Great Grade swords in the world. Wado Ichimonji is Zoro's most cherished sword, and it symbolizes his vow to become the world's greatest swordsman in honor of Kuina.
2. Sandai Kitetsu – A cursed sword, part of the Kitetsu series. It is a Meito sword but not considered one of the highest-grade swords like the Wado Ichimonji. The sword is infamous for its bloodlust and has a dark reputation, but Zoro chooses it because of its sharpness and potential.
3. Enma – A Great Grade sword that was once wielded by the legendary samurai Kozuki Oden. Enma is known for its ability to draw out a wielder's Haki, which makes it an incredibly powerful weapon. Zoro acquired Enma after Oden's death, and it is one of the most significant swords in Zoro's arsenal. It holds great potential, and over time, Zoro has been learning to master its unique properties.

These three swords are the ones Zoro has chosen to perfect his Santoryu style and pursue his goal of becoming the greatest swordsman in the world. Each of these swords is notable for its history, strength, and the unique challenges it presents Zoro as a swordsman.

In One Piece, Enma is classified as a Great Grade Sword. Great Grade swords are one of the three main categories of legendary swords in the One Piece world, with Supreme Grade and Great Grade being the highest grades.

Enma is one of the 21 Great Grade swords and is considered to be extremely powerful due to its ability to draw out the user's Haki, particularly the user's Conqueror's Haki, which makes it a challenging weapon to wield properly. It was originally wielded by the legendary samurai Kozuki Oden, and later, it was passed on to Roronoa Zoro, who continues to train with it in order to unlock its full potential.

While Enma may not be classified as a Supreme Grade Sword (like Yoru or Ryuma's sword Shusui), it is still among the top-tier swords in terms of power and historical significance.
