Sanemi Sword 101: Everything About the Green Nichirin Sword

Kimetsu no Yaiba’s heroes are all skilled martial arts practitioners with a talent for channeling their energy and leveraging it with their swords. These Demon Slayer samurai swords are called nichirin blades which are hand forged to correspond with its owner’s fighting style and personality. The Green nichirin sword was made to match Sanemi Shinazugawa who manipulates the winds with ferocity.

Who Is Shinazugawa Sanemi?

Sanemi Shinazugawa is a hashira, a high ranking Demon Slayer. This puts him above the likes of Kamado Tanjiro and Zenitsu, at least at the start of the show, and at the same level as Mitsuri Kanroji, the love hashira, and Rengoku Kyojuro, the flame hashira. As colleagues, they work hand in hand to crush demons and protect mankind.

Before he became a hashira, Sanemi was a regular young boy who grew up in an abusive home. He was the eldest of seven siblings and was often on the receiving end of his father’s abuse. After his death, Sanemi vowed to protect his family and his mother until his mother was attacked by a demon and became one herself. Because of this, he swore to become a member of the Demon Slayer corps.

Why Is Sanemi Colorblind?

The attack on Sanemi’s mother didn’t stop with her death. The demon who attacked her turned its attention on him and the rest of his family. This is why his only family member in the show is Genya, despite having had five other siblings before.

Sanemi himself barely survived the incident which is why we see him with so many scars and with broken eyes. The incident caused so much damage to his face area that his eyes became colorblind. A lucky stroke given that he could have ended up blind.

Their shared negative experiences about demons are why Sanemi and Shinobu Kocho are the most hostile hashira towards Nezuko compared to the likes of Inosuke and Tomioka.

How Strong Is Sanemi?

Sanemi is skilled with his Demon Slayer sword, but he is also quite powerful on his own. He is one of the more physically strong hashira and the powerful winds he summons can both restrain and injure his demon enemies. 

He is also incredibly smart. Unlike other hashira who began their demon killing career after joining the corps, Sanemi would use his rare, demon-intoxicating blood to incapacitate them before killing them. It was only after this that he was found by a real hashira and was then introduced to the organization.

Green Nichirin Katana Sword Facts

Zoro from One Piece may wield the most blades in anime, but Sanemi only needs one to excel. His green nichirin sword captures his brutal nature and his caring side all in one design, making it a worthy weapon to add to your wishlist. 

1. Sanemi’s Nichirin Blade Has A Wind Pattern

Sanemi’s nichirin blade and scabbard have a rippling and tearing pattern on them that is evocative of the whipping of fast winds. While Muichiro Tokito has a more relaxed image, owing to his Mist Breathing style, the two are differentiated because of Sanemi’s stormy wind theme. Sanemi’s sword does not symbolize the delicate winds, but the lashing winds of Japan’s typhoon season. 

2. It’s One of the Most Powerful Anime Swords in the Show

The Green nichirin sword has some of the stronger abilities in the show, barring the swords that are capable of keeping up with the flame breathing and sun breathing styles. The wind breathing style used with the Green nichirin sword comes with 9 different forms. These forms are able to cut enemies with lashes of fast moving winds. 

3. It’s Engraved With A Motto

Like other Demon Slayer swords, the Green nichirin sword is engraved with a motto “Kill All Demons” or “Destroyer of Demons”. This is symbolic of the hashira rank while also being a reminder of the Demon Slayer Corps mission to its wielders. 

Choosing Your Demon Slayer Cosplay Sword

Anime replica swords come in different styles and are made from several materials, each of which fill a different purpose and suit a different budget. Generally, the best in terms of value are wooden and stainless steel swords, provided that you’re buying a katana replica. Unlike carbon steel blades, these swords are affordable while being able to maintain the appearance of a real katana, particularly the curved blade that’s a hallmark of the sword type.

1. Stainless Steel Green Nichirin Sword Replica

Sanemi Shinazugawa’s Green Nichirin Blade

The stainless steel Green nichirin sword is a detail by detail copy of Sanemi’s sword from the anime. A particularly lovely detail of this replica is the starburst/flower shaped tsuba that resembles a stylized chrysanthemum. The sword blade has a wavy black and green hamon design but drops the sharpened edge that a real sword would have. 

This replica comes with its own saya or scabbard that you can store it in and wear on your hip for when you cosplay Sanemi. 

  • Material: Stainless steel
  • Overall Length: 102 cm

2. Wooden Green Nichirin Sword Replica


If you’re looking for a more stylized copy of Sanemi’s sword, look no further than the wooden Green nichirin sword replica. This sword deviates from the appearance of the sword in the anime in favor of having a more intricate tsuba, gold details, and a gold patterned saya. The green blade also pops more on this wooden replica as bamboo absorbs paint better than stainless steel.

  • Material: Bamboo wood
  • Overall Length: 102 cm


Sanemi Shinazugawa’s Green nichirin sword makes many appearances in Kimetsu no Yaibaall of them badass. The sword carries the history of its owner and the marks of its signature breathing style.
