Overview of Zenitsu Agatsuma

zenitsu sword

Demon Slayer: Kimetsu no Yaiba is one of the most famous and biggest anime TV series. In this Japanese manga series, the hypothetical world is filled with demons and their killers or slayers.

Slayers come from the Demon Slayer Corps, an institution set to defend Japan from the demons. This organization has been there since ancient times, committing itself to the protection of mankind from demons.

Each demon killer has a distinct sword forged using an uncommon ore blessed with the power of absorbing sunlight. Obviously, the sunlight is the main weakness of nocturnal demons.

One of the popular sword holders, demon slayers, and protagonists is Zenitsu Agatsuma. Regarded as the apprentice of Jigoro Kuwajima (a past Pillar), he travels with Tanjiro Kamado and his sister Nezuko Kamado to kill the demons.

Tanjiro Kamado is a primary demon slayer who is hunting for the demon who killed his family and made his sister a demon. While the special sword of Tanjiro is black, the Zenitsu sword is yellow. Both of them, along with other swords used in the series, are known as Nichirin blades.

They are known to take a distinctive color when their owners drag them out first. Thus, they are also called The Color Changing Swords. Nevertheless, the holder must possess some skill based on which the blade changes to a specific color when taken out.

The yellow Zenitsu blade symbolizes thunder. While the character is known to have low self-esteem and is infamous for being a coward, he never fails to show his true power when the situation is unfavorable. At the pace of lightning, his real strength gets demonstrated surprisingly as thunder itself.

As Nichirin blades tend to change as per the user, each of them is distinguished as unique. Zenitsu’s blade is distinct in the sense that its coloration is not a solid band but a lightning motif across the blade’s length. The reason for this show-up is unidentified.

Interestingly, Zenitsu can perform only a single move under the first style of Lightning Breath. This style is Thunderclap Flash that he has mastered such that he can frequently splash up to eight times in a single use.

Zenitsu Yellow Sword

A Nichirin blade designed for killing demons is made using a special ore that takes in sunlight incessantly. This makes it one of two ways to kill a demon by cutting his neck bone.

It is made using scarlet crimson iron sand as well as its ore extracted from the high mountains, like the one on Mt. Yoko. A Demon Slayer protagonist is allowed to opt for an ore after successively undergoing the Final Selection.

A Nichirin blade has a tsuba (called so in Japanese) or a handguard shielding the holder from cutting herself or himself. It is present where the blade and the handle intersect. It is also true that some protagonists removed the handguard from their swords.

The Zenitsu sword has a handguard in the form of a round with a golden rim and four minor indentations. The middle reflects a silver shade with petite triangles. Overall, it is a clover-type four-leaf tsuba.

This sword is purely a standard katana with white whirlwind streaks along the edge of the blade. This is unlike the other Nichirin blades having a solid color. The character is known to carry a white scabbard in which he keeps his sword.
