Demon Slayer: How Upper Moon Four’s Quirky Abilities Work

Demon Slayer has recently kicked its narrative up a notch with the entrance of Kibutsuji Muzan’s Upper Moons. If the Demon Slayer Corps had mostly been suffering defeats and deaths throughout its history, the times are changing. They have finally eliminated one of the Upper Moons, albeit the weakest among their ranks. But after the loss of one of his favorite subordinates, Muzan won’t remain on standby any longer and has begun mobilizing the Upper Moons to deal with the Demon Slayer Corps.

After waking from his two-month coma, Tanjiro Kamado went to the Swordsmith Village to get himself another sword. He goes through a relay of piggyback rides and ultimately reaches the secluded village, where most of the citizens are wearing masks. Tanjiro is supposed to take a breather, but he ends up training with the village’s treasure. The level-up he acquired is immediately put into use as two Upper Moons infiltrate and wreak havoc in the village. One of them, the seemingly weak-looking Upper Moon Four, takes on numerous Demon Slayers with a highly unique ability. Here’s what it is and how it works.

Demon Slayer’s Upper Moon Four Looks Very Meek – At First

What makes the demons in Demon Slayer formidable opponents is the various abilities they can harness. They possess impressive physical abilities, but also powers that are often singularly unique. Needless to say, the Upper Moons’ abilities are leagues above the Lower Moon and weaker demons, and Upper Moon Four is no exception. Its battle prowess lies in its ability to split and fuse.
Upper Moon Four’s base form is characterized as a considerably weak demon, lacking the immense power and capabilities that it gains after splitting and reuniting. In this form, Upper Moon Four is vulnerable and relatively easy to defeat, making it an underwhelming opponent for seasoned Demon Slayers. But underestimating its abilities would be a grave mistake, as its true strength lies in its ability to transform and adapt.
When faced with enemies, Upper Moon Four’s base form displays a distinct sense of fear and lack of confidence. It cowers in the face of the Demon Slayers, aware of its own vulnerability and the potential threat posed by opponents. Despite its initial hesitation and timidity, Upper Moon Four’s true potential comes to light when it finally uses its Blood Demon Art, revealing it to be a far more formidable and dangerous opponent.
Upper Moon Four Can Split Itself Into Many Powerful Warriors
The demons’ bane in Demon Slayer is decapitation, but that isn’t necessarily the case for Upper Moon Four. When beheaded in its base form, it undergoes a remarkable process of division. Each time it is beheaded, the base form splits into two separate demons, effectively multiplying itself.
The splitting process ultimately gives rise to five distinct demons, each representing an emotion and having a unique ability. The original Hantengu represents fear, and that remains consistent during its second form. But unlike the base form, this Hantengu is much smaller and more difficult to behead. Sekido embodies anger and uses khakkara to generate and manipulate lightning. Karaku is the manifestation of pleasure and uses a leaf-shaped uchiwa to generate strong gusts of wind. Aizetsu is that of sorrow and uses a yari to fight. Finally, there is Urogi, the manifestation of joy who has a physique akin to a harpy.

Unlike the base form, each of these demons poses diverse and formidable threats. Although one of them can’t take down a Hashira, they are capable of giving ordinary Demon Slayers a hard time. Urogi alone is shown to give Tanjiro a hard time by dragging the young Demon Slayer to a far-flung place, though it fails to eliminate the hero. But the group’s true threat comes as they work together. Given that they are technically just one demon, they are capable of perfectly combining forces, even giving Nezuko, Tanjiro and Genya a hard time.
It is also worth noting that Upper Moon Four’s Blood Demon Art allows for further division into smaller, more negligible demons. But unlike the five major personalities, these demons can easily be dealt with even without the use of Breathing Techniques. Nonetheless, this further multiplication of its presence on the battlefield could overwhelm opponents and make it harder to discern the true threat amidst the multitude of demons.
Upper Moon Four’s True Form Is Far More Formidable
Upper Moon Four’s true form is achieved through the reunification of the split demons. After the base form divides, it can merge them into a single, more powerful demon. This marks a pivotal transformation in Upper Moon Four’s abilities, heralding the presence of Zohakuten. Recent episodes of Demon Slayer have shown this is achieved by Sekido absorbing the rest. It remains unclear if the others also have the same ability.
This true form gives Upper Moon Four a substantial increase in power and strength. The combined entities merge their individual capabilities, resulting in a formidable adversary for the Demon Slayers. This heightened power enables Upper Moon Four to unleash devastating attacks and exhibit a greater level of control over its abilities.
Zohakuten exhibits the peculiar ability to command dragon-shaped wood as a weapon. These uniquely-shaped earth formations serve as both defensive barriers and offensive weapons, enhancing Upper Moon Four’s offensive capabilities and making it a formidable force to reckon with. As Zohakuten has only recently appeared in the Demon Slayer anime, it won’t be surprising if there are more unrevealed forms and powers to come.
