If a Bushi commits Seppuku and is accepted by Fudo Myo-o, their body will transform into two objects; a Soul (魂,Tamashii?) and a Key (鍵,Kagi?). After that, the Key and the Soul are spontaneously assembled from the Locker Ball. The Locker Ball forms a new robotic body and a new Samurai is born with a Threefold Body.
The Samurai Soul represents a rod that splits (断つ,Tatsu?, lit. to cut off) objects in two, the opposite to a Samurai Key (侍の鍵,Samurai no Kagi?) which represents a rope that binds (繋ぐ,Tsunagu?, lit. to tie/connect) one object to another.
Some Samurai may have more Samurai Souls within themselves than their own like Ryu and Benkei while others have Souls around your body like Ata, Mujin and Future Hachimaru.
Abilities and Powers
The Samurai can take their Samurai Soul from their body in the form of a orb and attach it to a Handle Bone to create a blade to be used in combat. The Samurai Soul Blade (侍魂の刀,Samurai Tamashī no Katana?)is the Samurai true weapon. While many Samurai form a sword from their Soul, they can be shaped into other weapons like scythes, axes, spears and tridents.
