One Piece Sets a New Devil Fruit Class Beyond the Mythical Joan

one piece Chapter 1 of the July 18, 1997 story introduced the Devil Fruit concept as a power system. Since then, series creator Eiichiro Oda has greatly expanded this system, introducing various classes such as Paramecia, Logia, and Joan, as well as other subcategories such as Ancient and Mythical Joan. Most devil fruits in the world are one piece Falling into this category, the climax of One Piece's Elbaf Arc, which was released in the 19th issue of Shueisha's Weekly Shonen Jump on April 6, 2026, especially Chapter 1179, revealed the power of Nerona Imu's Demononomy. This devil fruit is the most unique devil fruit in the world of One Piece and exists as its own class, surpassing all classes existing in the world of One Piece.

Nerona Imu's Akuma No Mi breaks the Devil Fruit class and surpasses the mythical Zoans.

until recently one pieceThe rarest Devil Fruit subclass was the Mythical Joan, introduced along with Marco's Toritorinomi, Model: Phoenix, in Issues 37-38 of Weekly Shonen Jump in Chapter 553 of the story on August 10, 2009. The Mythical Zoan class has been officially introduced to be much rarer and more impressive than Logia. Over the years, the mythical Zoan Devil Fruits have eclipsed even people like Logia and left a great legacy for themselves.

Most of the mythical Joan Devil Fruits recently introduced in One Piece, such as Luffy's Hitohitonomi, Model: Nika, Loki's Ryuryunomi, Model: Nidhogr, and even Risuri's Nomi, Model: Ratatosk, revealed in One Piece Chapter 1183, far exceed the average Logia Devil Fruit in terms of strength and special abilities. Despite this, all of these Devil Fruits still exist and function within the class realm that Eiichiro Oda has established over the years.

With the reveal of Nerona Imu's Demonic Beauty in Issue 19 of Weekly Shonen Jump in 2026, Eiichiro Oda has now officially introduced a Devil Fruit class that surpasses other classes and exists in a league of its own. Akuma no Mi by Nerona Imu is incredibly special. It boasts the most powerful firepower among the Devil Fruits that exist in the world of One Piece. But what makes this ability unique isn't its firepower. In fact, it is the very classification introduced in Chapter 1179 that sets it apart from all other fruits in the world, including the extremely rare mythical Joan.

Why Imu's Demononomy is not part of the Devil Fruit series

The main reason why Nero or Imu's Demon Beauty surpasses all other Devil Fruit classes is its special name. All devil fruits that exist in the world of One Piece are named in Chinese characters. However, “Akumanomi” has a unique name written in katakana that sets it apart from the others. Unlike other Devil Fruits that exist in the One Piece world, all Devil Fruits have a dual naming pattern, such as Luffy's Hito Hito no Mi and Model Nika. Jiki Jiki no Mi by Eustass Kid; Or even Blackbeard's Yami Yami no Mi.

Every fruit that exists in this world created by Eiichiro Oda has a dual naming pattern. Imu's Akuma no Mi is the only one that exists with a single naming pattern. And that's not all. The name itself contains the meaning of 'Devil's Fruit', which means that it is the ultimate Devil Fruit ability in this world and that it destroys existing classes.

Loki: So your power is the rule of God? It's like a contract with the devil!

Imu: Oh my god? devil? What is the difference?

Moreover, Nerona Imu's Akuma no Mi ability is definitely unique in the way it operates. On the surface, this Devil Fruit appears to be a mythical creature that allows Imu to transform into the demon god of the world. However, the way permissions work is unique. There doesn't seem to be a full Zoan or hybrid form in imu. Instead, he simply has demonic transformations and numerous powers that don't fit any specific category.

For example, Imu has the ability to utilize grimoires in battle. This spellbook is very deadly as it consists of numerous spells that have various effects on enemies. Moreover, Imu can also make contracts with other people, this ability does not fit into the mythical Zoan class and is more of a sign of the Paramecia Devil Fruit. Likewise, Imu can also utilize the power of Domi Reversi, which once again has no clear classification. Lastly, the unique ability to control Omen's black flame, which was officially revealed in the 21st issue of Shueisha Weekly Shonen Jump in One Piece Episode 1180 on April 20, 2026, becomes even more strange. Eiichiro Oda also did not confirm the classification of Akumanomi, making it a unique devil fruit and placing it in its own class.

Nero Naimu's Devil Fruit is the most unique Devil Fruit in the world. one piece As of now, there are some who break some of the rules of the Devil Fruit. For example, Luffy's Hito Hito no Mi, model: Nika, is unique in that despite being a mythical creature, it displays the properties of a Paramecia-type Devil Fruit. Luffy's mythical Zoan Awakening should only give him a transformation, but he can also transfer his powers to those around him through this Devil Fruit ability, as Kaido mentioned in Chapter 1045, released in WSJ Issue #18 on April 4, 2022.

“It’s safe to assume that you have awakened the Paramecia Fruit since you can transmit your power to those around you. But something is strange! This transformation is typical of Zoan Awakening!” — Kaido explains Luffy's special Devil Fruit awakening. One Piece Episode 1045

Not only that, but Luffy's Fruit allows him to transfer his powers to other creatures through Awakening, making him the only person in the entire series capable of doing so, and breaking quite a bit of the laws of Devil Fruits in the process.

Along with Luffy, there's Charlotte Katakuri to consider, whose Devil Fruit is the only one in the entire series that falls into the Special Paramecia category. Considering that Eiichiro Oda has already broken quite a few of the rules of his Devil Fruit class, it's likely that Imu's Devil's Beauty will also break quite a few of them and establish his own class at the same time.
