376. Execution, Extinction 2

Aizen prepares to confront six Shinigami and six Vizard after effortlessly defeating Harribel. Meanwhile, Mashiro and Kensei fight Wonderweiss.

Summary
The chapter opens with Aizen commenting on how he never thought he alone would be "more powerful than the lot of you," referring to the Espada. Harribel begins to fall from the slash across her midsection, but angrily stabs Aizen in an act of revenge. Aizen is impassive and he stabs her from behind in her left shoulder blade and comments how she "will never raise a sword" to him again. Harribel had stabbed a hypnosis clone. Harribel then falls to the ground and Aizen turns to his surprised enemies and says "Come on, let's get started....Gotei 13 and you shoddy Arrancar wannabes."

Meanwhile, on the ground, Mashiro notes that the last Espada is dead, but then Wonderweiss awakens from unconsciousness in the crater that Mashiro kicked him into. After a quick warning from Kensei, Mashiro kicks Wonderweiss into a broken building. Kensei then warns her that she will wear out her mask if she keeps fighting for too long with this level of opponent. She dismisses his warning as stupid and claims she is good for another 15 hours, just as Wonderweiss defiantly leaps out at her. She grabs him and smashes his face into the ground, but, with a shout, he grabs her scarf and throws her through a few buildings, tearing the scarf in the process. Mashiro angrily proclaims that he shouldn't have torn her scarf and then she shoots her "Mashiro Super Cero" at him via a kick. He neutralizes it by swallowing it and she says "so what?!" and pulls him in for a punch. As she does, her mask begins to break and Wonderweiss happily yells and punches her in the face. As he is about to hit her again, Kensei steps in and grabs a now unconscious Mashiro while blocking Wonderweiss's punch. The chapter ends with Kensei saying that he "isn't the sort of adult who goes easy on kids."
