Name: Muramasas
Type:Weapon
Ability:Can be channeled with chakra and would have a different effect with each release but is only able to be as strong as the user. If the blade receives blood, then the sword would repair itself almost instantly.
Appearance: The blade is 42 inches long and has a pitch black straight blade with a red handle wrapped in black rope. It is held inside a black scabbard with a red wrap.
History: The sword has been passed down from the Kuronuma line as a potential equal to the Seven Ninja Swordsman of the Mist's swords. Kazuma's brother was the one to hold the sword initially because he was the oldest child but handed it to Kazuma due to his inability to walk.
