Background / History

Aizen publicly renounces Soul Society's order during his confrontation with its captains. Seeking “a higher place,” he declares that no being—not even gods—has stood in the heavens, and vows that he will occupy that position himself. His ambition is visually marked by removing his glasses and sweeping aside the bangs that had concealed his eyes. 296

He regards the Five Great Noble Clans as betrayers who reduced the Spirit King to a symbol. His intended revolution is to overturn their ruling system, expose the truth of the Spirit King, become the new Spirit King, and lead the world into a different future. 300

When Hoshiryu proposes a contest between Aizen's side and Yamamoto's faction, with the Spirit King's power as payment and future employment under Hoshiryu as the prize, Aizen accepts immediately. He sees the offer as a route to surpassing the Death Gods, though he also considers Yamamoto's continued leadership an obstacle to his ambitions. 299 300

After leaving Soul Society, Aizen establishes himself in Las Noches and merges his own Hogyoku with Kisuke Urahara's, creating a complete Hogyoku. He later survives near-fatal injuries inflicted by Hoshiryu; his wounds visibly regenerate until no injury remains. 309 311

Hoshiryu's attention to Ichigo convinces Aizen that Ichigo is a destabilizing threat. He sends Ulquiorra and Yammy to the Living World with orders to eliminate Ichigo, then personally attacks him. Ichigo's Hollowfied power overwhelms Aizen's defenses and forces him to retreat to Hueco Mundo through the Anti-Barrier. 335 337

Refusing to remain beneath Hoshiryu, Aizen accelerates his plans. He launches a mass Menos invasion of Soul Society, activates the Hogyoku, and draws in spirit particles on a scale that threatens the balance of the three realms. His rebellion ends with Hoshiryu confronting him directly and freezing him in place through the world's laws. 340 342 344 350

Appearance

Aizen initially presents himself with glasses and bangs that partially conceal his eyes. When declaring his ambition, he removes the glasses and sweeps back his hair, exposing an intense, ambitious gaze. 296

• Wears glasses before revealing his true intentions. 296
• Keeps his bangs over his eyes until his declaration of ambition. 296
• Is left covered in blood and severely wounded after Hoshiryu's warning, though he later heals completely. 310 311

Personality

Aizen is calm, calculating, and highly ambitious. Even when facing Hoshiryu's overwhelming power, he attempts to maintain a composed manner and searches for opportunities to turn events to his advantage. 296 310 311

He is deeply contemptuous of Soul Society's noble order and believes he alone is suited to replace its false hierarchy. His desire to stand above others, however, also makes him unwilling to accept Hoshiryu's authority or the role Hoshiryu offers him. 300 339 342

His methods are ruthless and pragmatic. He is willing to use Ulquiorra and Yammy as sacrifices in a scheme against Hoshiryu, attempt to erase Ichigo before his potential can mature, and exploit Soul Society's instability for his own goals. 319 335
