Calamity Curse is one of the most powerful villains in Spell Wars, so let's break down their realms and how they work.
The Curse of Calamity in Jujutsu Kaisen are powerful villains who are essential to character development, and they possess incredible cursed energy and technology.
All four Calamity Curses are able to use the ultimate technique, Realm Unfolding, demonstrating their strength and skill as warlocks.
Each Calamity Curse unfolds in a unique realm, such as Hanago's Ritual Sea of Light and the perfect incarnation of the True Person's own, all of which enhance their abilities and pose a serious threat to their opponents.
The curse of Calamity in Jujutsu Kaisen is the most powerful and important villain in the entire story. This is because not only are they obstacles that the heroes need to overcome, but they are also at the heart of the overall character development of other characters such as the importance of real people to the arc of Knotweed Yuhito. These, combined with their incredible cursed energy and technology, make them one of the most powerful characters in the series.
This is further exacerbated by the fact that all four Calamity curses can use Spell Kaisen's ultimate technique, Realm Unfolding. This technique is very difficult to master and use correctly, as only the most powerful and skilled warlocks can do it, which further shows the power of these curses, as they are all able to open their own realms. So, let's take a look at these areas and what they do!
Realm unfolding is considered the pinnacle of spells, and it is so rare in the world that even most first-level warlocks cannot perform it. Since each warlock has an innate or inherited technique, they all have the potential for realm unfolding, although this is still very difficult to achieve as it requires a huge amount of curse energy to do so. Even those who are capable, they can only perform it once a day due to the immense strain it causes on the brain.
The field development is the strongest possible use of a person's technology. This is because when cast, the innate domain within the user's brain is externally revealed as a barrier, the walls of which are framed by the technology itself. When inside this barrier, their curse technique is strengthened and gains a sure hit, whether the effect is lethal or non-lethal.
The realm is activated through each person's unique mudra and the slogan "Realm Unfolds". For the most part, these realms create barriers of varying sizes, and although only the two-faced sufu and the sorrel have such a refined and powerful realm spread out that they manifest in the real world, rather than within the barrier, the sure effect of their technology remains.
Hanami is the only one that doesn't show the realm unfolding in the anime or manga. The only time it was about to use this attack was at the end of a friendly match, when it was fighting Knotweed Yuhito and Aoi Todo, Hanami showed off its black arms with a giant flower on its shoulder.
Just as it uttered the words of the Activation Realm, the Sea of Light Rituals, the curtain that prevented Satoru Gojo from entering the school was destroyed, interrupting the attack that could have taken the lives of Knotweed Yuhito and Aoi Higashido. While the exact properties of this realm are unknown, Hanami's curse technique, the Calamity Plant, will play a major role in it, giving the barrier the form of a garden or forest, filled with plant life infused with cursed energy.
The Dhagogen is a calamity curse produced by humanity's collective fear of the ocean, and he and his curse technology fully encompass this. His innate technique, Calamity Tides, allows him to summon huge and seemingly endless waves of water formed by his cursed energy, capable of overwhelming and overpowering his opponents. In addition to this, the dagoon can also summon many fish-like gods.
The realm of the dagoon initially looks very beautiful and tranquil, taking on the shape of a sunny tropical beach. However, once inside, Dogon is able to summon endless waves of Shikigami that will attach themselves to his enemies, effectively devouring them alive, as seen in his battles with Nankai, Maki, and Naoto. This is an extremely powerful realm, because Shikigami is endless and will always hit the target. The only reason the Warlocks were able to survive was because Shir's lack of curse energy meant that Shikigami couldn't target him, and his physical abilities were too powerful for them or Dhagons.
Leaky's field expansion is one of the strongest in the entire series. Since Leaky Woo stems from the human fear of fire and volcanoes, his natural skill is to completely manipulate and utilize fire, which is also reflected in his powerful realm. The exterior of the Iron Mountain Coffin is the interior of an active volcano, and its properties can be fully controlled by Leakage.
The ground in this realm began to spew lava, making it possible for only the most skilled warlocks to survive. In addition to the drastic increase in temperature, Leaky can manipulate various structures within the realm, and he can pick up huge rocks and boulders to crush enemies or burn them alive with lava. However, the only time he uses it is against Satoru Gojo, who overwhelms the realm with his infinite void.
The real man is the strongest of all the curses in Jujutsu Kaisen, and his curse technique, idolatry, is a testament to the power he possesses. This technology allows him to "change the shape of a person's soul", which essentially means that he can change the essence of a person by turning an ordinary person into a shape-shifting creature that destroys and kills for him because it knows nothing else. In addition to that, he can transform his shape into whatever he wants.
Self-perfection is undoubtedly one of the most powerful and dangerous areas of unfolding in the entire series. Since all realms have a must-hit effect, the real person instantly connects with the soul of anyone trapped within his barrier, meaning he doesn't need to touch them personally. The barrier of the realm itself is formed by the hands of many real people, suggesting that idolatry will affect people anywhere within the realm.
The real person has such a great grasp of his technique and domain that he can adjust the scope and activation time of the realm like Satoru Gojo. As seen in the Shibuya incident, the real person only activated 0. for Knotweed Yuhito and Aoi Todo after seeing it once from Satoru GojoThe realm unfolds in 2 seconds, which makes him the strongest Calamity Curse of all of them!
