In Chapter 1180 of a piece The Elbaf arc, which was released in Shueisha's Weekly Shōnen Jump issue 21 on April 20, 2026, expanded on Eiichiro Oda's many powers existing in the world. a piece a lot This chapter marked the descent of Nerona Emu, king of the world, who is also the final villain of the story, to Elbaf. With the goal of eliminating the threat of Nika and Nidhogar once and for all, Emu set foot in the Underworld for the first time in hundreds of years. Naturally, in doing so, the Nerona emu also showed its fair share of abilities.
Nerona Emu possesses the power of Akuma no Me, or the Devil's Fruit, which is one of the most interesting abilities that exists in the world of One Piece. Using this power, he gains access to many abilities, but the one that stands out the most is Omen, also known as Maki. This Omen is a very special power that holds the key to Roronoa Zoro getting his next upgrade in the story, that is, the Black Blade, or Kokuto.
Nerona Emu's Omen Power may hold the key to blackening the swords in one piece
Black Blade is considered very special in the world a piece. So far, only two Black Blades have appeared in the story, and both of them are incredibly special. The first black blade that Eiichiro Oda featured in the story was the Yoru, a 12th highest rank sword wielded by the world's strongest swordsman, Dracul Mihawk. This sword officially debuted in Chapter 49 of One Piece and has since become an integral part of sword lore in the world.

Then, in a fragment chapter 448, Eiichiro Oda unveiled another sword, a black blade named Shusui, which was a lost treasure of the Wano country. This sword was wielded by the zombie Ryuma's corpse and eventually given to Roronoa Zoro. Zoro took this sword back to the land of Wano and received Enma as a true replacement for this blade. Apart from these two swords, there are no other black blades in the world of One Piece. Now, years later, in the Elbaf arc, Ichiro Oda has revealed a special power that could be the key to Zoro blackening his swords in the final saga, and that is Nerona Emu's Omen.

Why is it necessary to forge an omen cockatoo
Emu used the power of the Omen in a battle against Zoro, Sanji, Hajarudin and Loki in One Piece chapters 1180 and 1181. According to the King of the World, Omen is his military power, and it is the power that resides in all living beings. However, not everyone is able to bring out this power. For some reason, using Akuma no Mi's power, Omen manipulation becomes possible. As it is the military power of the emu, the omen can also be conferred on others. For example, when a person like Rox was domi reversed, it is very likely that he was significantly enhanced in terms of power, using the same omen. Similarly, when Harald was granted the power of the Deep Sea Covenant, he also received the power of the Omen in a different shape and form. Emu can directly manifest and give omens to anyone, as shown in chapter 1180, where he gave omens to both Somers and Killingham.
Receive a unique dark energy powered with Omen. To understand the power given by the omen, it is necessary to look at the etymology of the word. Omen is known as Maki in Japanese, and is very similar to Haki both in how it is pronounced and the concept behind the energy. Haki simply refers to spiritual energy in one piece. Meanwhile, Maki refers to demonic energy. Both these powers reside in all beings. The only difference is that demonic power can only be brought out when one gives it to Satan or makes a deal with Satan, and spiritual energy is awakened through a different training method.
Interestingly, every weapon produced by Nerona Emu using the power of Omen is completely black in color. Dori and Brogi also, after Domi was reversed, had black blades at their disposal, displaying the monstrous power of maki infused into the blade. This is a lot of demonic energy that can be very good to get the black blade in one piece. By killing someone bathed in demonic energy, or learning to infuse the demonic energy into oneself, one could potentially gain access to a permanent black blade. This is why Zoro's upcoming fight against St. Somers in Elbaf and later, the Five Elders or other allies of Emu are important.

How Mihawk and Ryuma got the Black Blade Yoru and Shusui respectively
If Omen or Maki needed to make the Black Blade, it begs the question of how Ryuma and Mihawk got their Black Blades. There are many powerful swordsmen in the world a pieceLike Rox, Roger, and even Shanks, but none of them had a black blade. Yet, somehow people like Mihak, who could arguably be weaker, have this sword.
The key is how the blade was forged. In Chapter 937 of a pieceIt was officially stated by Onimaru that Ryuma forged his black blade through the countless battles he participated in. On the other hand, there is no indication of how Mihawk got his black blade, but One Piece chapter 1181 strongly indicates a relationship between Nerona Imu and Dracule Mihawk. It is very likely that before Mihawk went his own way and broke Nerona's bond with Emu, he killed someone bathed in the same power of Omen, which permanently made his black blade.
The story of Ryuma slaying the dragon in the Flower Capital is one of the many legends of Ryuma as a swordsman. Since his death, Shusui has become a national treasure! – Gyukimaru, One Piece Chapter 937
Similarly, centuries ago, Ryuma is said to have slain a giant dragon in the land of Wano. If this dragon was somehow bathed in the power of the omen, then this would explain how Ryuma's Shusui became a black blade and gained great durability. Following the same train of logic, Roronoa Zoro would have had to kill someone bathed in the Omen's power or learn to control the Omen's power through abilities such as Kiki Kutoriu: Asura. Sooner or later, Zoro will upgrade his blade, and when that happens, he will take a step closer to dethroning Dracul Mihawk as the strongest swordsman in the entire world.
