The Otaku Armoury: Sekiro’s Shinobi Prosthetic Arm

The Otaku Armoury highlights Japanese weaponry that has been used throughout popular culture. Games like Mortal Kombat and Devil May Cry have incorporated singular weapons such as a katana, whereas games like Sekiro: Shadows Die Twice have offered multi-purpose tools. The game’s protagonist, Sekiro, wields a prosthetic arm that houses all kinds of traditional Japanese weaponry.

A weapon for every situation

As a shinobi, Sekiro is tasked with protecting the Divine Heir Kuro from Genichiro Ashina, the grandson of the legendary warlord who seized control of the land of Ashina years before. Early on in the game, Sekiro loses his arm in a fight with Genichiro and awakens in an abandoned temple.

A mysterious man known as the Sculptor replaced Sekiro’s arm with an advanced wooden prosthetic that contained many tools and gadgets. Let’s look at each one:

Grappling Hook

As the first gadget Sekiro received, the grappling hook was a handy tool that allowed him to reach high places and escape from danger quickly.

It is made of a thick rope with a kunai attached to the end and is likely based on a traditional Japanese kaginawa, a versatile tool used by samurai and ninjas. The kaginawa could be used to scale walls, hang armour and secure boats.

Loaded shuriken

The prosthetic contained a mechanism that allowed Sekiro to launch shuriken at high speeds. Also known as throwing stars, traditional shuriken came in many different shapes.

While popular culture has portrayed shuriken as ninja weapons, they were not actually wielded by warriors who practiced ninjutsu. Instead, shuriken were employed by samurai and ashigaru soldiers as injuring weapons.

Shinobi firecracker

An important distraction tool, Sekiro used the firecracker to create a burst of light to blind enemies. It is an extremely useful weapon when fighting against opponents on horseback.

Flame vent

One of the most powerful weapons in Sekiro’s arsenal, the flame vent unleashed a wall of fire that burned foes and ignited his sword.

The flame vent may have been based on the Chinese fire lance, which consisted of a gunpowder filled bamboo tube strapped to a spear. When ignited by a match, the lance would spray flames onto the enemy.

Loaded axe

The loaded axe is a powerful weapon that can cut through shields in a single swing.


Translating to ‘rustblade,’ Sabimaru is a sword that inflicts poison damage on foes. Sekiro wielded it with deadly purpose, cutting through his opponents with ease.

Loaded spear

Sekiro gained the loaded spear after beating a boss called Gyoubu Oniwa. Crafted from Oniwa’s broken horn, the spear is an excellent thrusting weapon that drags enemies towards Sekiro.

Mist raven

Magic is an important part of Sekiro: Shadows Die Twice and the mist raven is a useful magic-based tool. It grants Sekiro the ability to turn into black mist and teleport to a new location.

Loaded umbrella

The loaded umbrella is another useful defensive tool. Made from iron and shaped like a shield, the umbrella helped Sekiro block attacks and plan counter strikes.

Divine abduction

This prosthetic tool took the shape of a giant fan that surrounded Sekiro in whirling winds. The fan could hide the shinobi from enemies and even spirit them away, providing a quick escape route for Sekiro or giving him the chance to attack.

The divine abduction is based on Japanese war fans that could be utilised for offensive and defensive purposes. Warriors might use them to parry sword strikes or stab opponents at close range.

Finger whistle

The finger whistle is a useful distraction tool for beasts like wolves and dogs. When used, the finger whistle enrages animals and draws them towards a desired location, causing them to attack anyone on sight.
