title: The Developer of the Modified Souls
Yoruichi explains that she had sent word to Kūkaku Shiba about the situation and she arrived with Jidanbō Ikkanzaka and Ganju Shiba to assist the captains in their fight with Inaba. They then healed their injuries at Kūkaku's home and waited for an opportunity to strike back.
Captain Kenpachi Zaraki attacks the Reigai and tells Ichigo, Urahara and Kon to get out of the way. Yoruichi tells the trio to leave the Reigai to them and they leave as the captains begin the fight.
