You are fighting out of obligation, not out of hatred. You will never reach me like that. Battle without hatred is like a bird without wings. You’ll never defeat anyone like that. Your powerless friends are just weights that will break your legs.
~ Aizen Sosuke

  • Named “Kyōka Suigetsu”.
  • Utilizes the Shikai Form & "Complete Hyponisis" Ability.

  • Number 61: Rikujōkōrō
    • Pointing his index finger at the target, Aizen generates a spark of yellow energy, which summons six thin, wide beams of light that slam into a target's midsection and hold them in place. The target is unable to move any part of their body, including the parts which were not struck by the beams.


  • Number: 90 Kurohitsugi
    • Kurohitsugi is a high-level Kidō which seals its target in a black spiritual coffin. The practitioner generates purple/black spiritual energy, which envelops the target with a powerful torrent of gravity before taking the form of a box of black energy, covered in several spear-like protrusions which pierce the box, lacerating the one inside from head to toe. The spell is very difficult to use, as Aizen could only unleash a third of its power without chanting the particular incantation when he used it on 7th Division Captain Sajin Komamura.
  • Number 99: Goryūtenmetsu
    • Upon activation, energy ruptures a large area around Aizen, causing the ground to rise up in pillars, before rising into the air to form five enormous dragons above him. This attack is undoubtably Aizen's strongest attack
