Masijiro Hamato holds the Third seat in the 3rd Division.
Masijiro's Zanpakuto is called 'Samurai', and its release command is "Uphold". The Zanpakuto simply glows silver after the command, but has become stronger and will cut through any ordinary Zanpakuto. People have remarked over the unimpressiveness of his shikai, but Masijiro has retorted that he does not need Samurai to transform into any elaborate form. The form it was already in is perfect in his hands.
Samurai's Bankai is 'Bushido Samurai'. This combines with Masijiro, with Samurai armour forming around his body. The armour is virtually unbreakable.
