The narrative of the Swordsmith Village Arc reveals four primary clones, each representing a fundamental human emotion and possessing a corresponding power:
Aishō (Sorrow)
The clone embodying sorrow is often the first to appear and is characterized by its mournful cries and a generally melancholic demeanor. This clone's primary ability is to induce feelings of sadness and despair in its opponents, weakening their resolve and making them susceptible to other attacks. It can also manifest as a large, lumbering beast, capable of powerful physical attacks, often driven by a misplaced sense of tragic purpose. Its attacks are often imbued with a chilling aura that saps the will to fight. Many demon slayers underestimate the psychological impact of this clone, failing to realize that emotional manipulation can be as deadly as a physical blow.
Kōkotsu (Hatred/Anger)
This clone is the embodiment of Hantengu's rage and resentment. It is typically the most aggressive and physically imposing of the clones, often appearing as a monstrous, horned beast. Its attacks are brutal and relentless, fueled by pure fury. Kōkotsu's primary ability is to unleash devastating physical assaults, often with incredible speed and strength. It can also emit a powerful sonic scream that disorients and injures those who hear it. This clone is the brute force of Hantengu's arsenal, designed to overwhelm through sheer destructive power. Its unbridled aggression makes it a terrifying opponent, capable of shattering defenses and crushing spirits.
Jōyō (Joy/Pleasure)
The clone representing joy is perhaps the most insidious. It often appears as a smaller, more agile, and seemingly harmless entity. Its primary ability is to taunt and distract opponents, often with unsettling laughter and playful, yet deadly, movements. While not as physically powerful as Kōkotsu, Jōyō is incredibly fast and elusive, making it difficult to target. It can also manipulate its surroundings, creating illusions or traps to disorient and ensnare its foes. The deceptive nature of this clone is its greatest weapon; it lulls its opponents into a false sense of security before striking with surprising ferocity. Its ability to sow confusion and amusement before delivering a fatal blow is a testament to Hantengu's twisted genius.
Zōo (Pleasure/Lust)
While often less emphasized than the other three, the clone representing pleasure or lust is still a significant threat. It typically manifests as a more serpentine or avian creature, capable of swift, piercing attacks. Its abilities often involve ensnaring opponents or delivering swift, precise strikes that can incapacitate. This clone embodies Hantengu's desire for self-preservation and the pursuit of fleeting pleasures, even in the midst of battle. Its agility and precision make it a dangerous opportunist, striking when an opponent is distracted or weakened by the other clones. The subtle danger of this clone lies in its ability to exploit openings with unnerving efficiency.
