A katana given by Kuro, the Divine Heir. An heirloom of the Hirata family, a cadet branch descended from Ashina.

Once thought lost, it has found its way back into the hands of the Wolf.

The name Kusabimaru beseeches, "A shinobi's role is to kill, but even a shinobi must not forget mercy." A mantra the blade itself may manifest.

Kusabimaru (Japanese: 楔丸) is a Key Item in Sekiro: Shadows Die Twice. It is used to to attack Enemies and deflect attacks. This is the primary means of combat in Sekiro.


 Kusabimaru Usage

  • Used to attack and defend while in combat.
  • By pressing the R1/RB, Sekiro can perform up to three consecutive hits.
  • Holding down the R1/RB results a thrust attack, which can penetrate enemy defenses. The longer it is charged, the more damage and it inflicts, with higher chances to pierce.
  • Sekiro can block incoming attacks by holding down L1/LB; absorbing damage builds-up his Posture.
    • By pressing L1/LB right when the enemy attack clashes with Sekiro, he will perform a Deflect, which will inflict Posture damage on his foe instead, opening for counter attacks.

Kusabimaru Notes & Tips

  • Kusabi (楔) is Japanese for "linchpin," while maru (丸) is a common suffix used in masculine names.





Story & Lore

  • Kuro comes from 九 (ku) meaning "nine" and 郎 (rou) meaning "son". This name was traditionally given to the ninth son. The name likely  refers to the nine sons of the Dragon King "the dispenser of rain". But "Kuro" is also a Japanese kanji  (黒) meaning “black”. Sekiro, the vengeance-seeking "Shinobi" - which in Japanese means both “ninja” and “shadow” - is a wink to previous game titles in which the player could sign up to become a "Blade of the Darkmoon [1].", a shadow of the divine lineage of DS. This was also a covenant presided over by the Dark Sun Gwyndolin. The white taint that surrounds Sekiro's eye is a manifestation of the Dragon Stagnation. Which is caused by Sekiro's immortal oath to the heir of the dragon. The mark serves as a Sekiro symptom of Hollowing White Darksign - DS1 Lucatiel's Darksign - DS2. Kuro's bare feet are another legacy that stems from the dragon children of DS. This is likely because of a dragon-like resistance to the cold of autumn and winter.


  • Kusabimaru 楔丸 - given by the Young Lord - was named in honor of the Lynchpin Temple “The Nexus of Souls”.

      The best sword is a reliable one. Kusabimaru is small, light, sturdy and reliable; perfect for a wielder who understands finesse and balance.

        This katana: Does maybe 1/20th of an enemy's hp bar per hit Katana of a generic grunt: Does 1/3rd of my hp bar per hit Its more effective as a shield than a weapon tbh

          Considering how many hits it blocks and how many lives it takes throughout the game without breaking it's actually a damn good weapon despite its unassuming design.

            This seems to be the shortest katana in the game. Genichiro, Owl, even trash mobs have more range. Oh how I wish the Mortal Blade was an alternate weapon.

              Everyone else's sword hits you for over 20% of your health each time, yours hits for less than 5% of theirs. I think this guy's trying to do a broken sword run.

                I got a different description. After the bit about finding its way back to Wolf it says “Both sheath and hilt are an unassuming solid black. It’s name means ‘ties with that which is precious’, and it’s said the blade embodies this sentiment.”
