Bleach Volume 43

Despite Suì-Fēng's reluctant for his help, Hachi makes a deal to trap Kisuke in a barrier for a month if she helps him by using her bankai to hit Baraggan. Baraggan survives, but furious that half of his face has been destroyed as he unleashes his Respira as it comes in contact with Hachi's right hand. However, in a gambit on the nature of their opponent's defense, Hachi removes his hand using a barrier and transports it inside Baraggan's body where the Espada begins to suffer his own power. In his final moments, remembering how he was once the ruler of Hueco Mundo until dethroned by Aizen, Baraggan makes a final attempt on Aizen. Though Stark's victory seems assured as Baraggan's death stirred him to take the fight seriously, Stark is unexpectedly killed by Shunsui. Meanwhile, Wonderweiss gets the upper hand against Mashiro before Kensei steps in to save her and takes her place. In a turn of events, having deeming the Espadas are too weak to serve him after witnessing Stark and Baraggan's deaths, Aizen decides to join the battle after dispatching Halibel and leaving her for dead. Despite Shinji's warning not to let Aizen's words get to them, Hiyori loses it and finds herself badly injured by Gin when she made an impulsive rushes towards Aizen.
