The filler episode involves a zanpakuto that killed its owner, causing other zanpakutos to follow their instincts and attack their masters. In the current episode, Hyorinmaru, Zabimaru, Haineko, and Tobiume have been captured or turned to the good side again. The filler interrupted the story where Espada 1, 2, and 3 with Aizen, Gin, and Tousen were in Karakura Town trying to obtain the King's Key. They had killed all the Arrancar and trapped Aizen in a fire prison while the Espada were fighting 3 captains and about to use resurrection.
