• Unohana fights Zaraki
• Everyone training for the upcoming war | TYBW Arc | | - Aizu reads Unohana’s will and debates that if Unohana does die in that fight, would she want to be promoted as captain? After all, Jushiro had long planned to retire (originally planning on handing his position off to Kaien before he died) and would most likely do so after this war with the Quincies.

They spend one last day together before he goes off to perform the Kamikaze. | | - Second Invasion Begins | TYBW Arc | | - She helps gather and heal injured Shinigamis.

• Everyone arrives at the Soul King Palace | | | - She activates her bankai is the far-off distance to avoid the storm affecting other people’s fights and to avoid being within Shunsui’s bankai range. She helps Shunsui and Nanao defeat Lille Barro with her ult attack (since her bankai is like “God’s Judgement” or something like that LMAO, somewhat fits thematically or whatever lol)

• Aizu becomes the Vice-President of the Shinigami’s Association as Rangiku becomes the President and Yoruichi becomes the Chairwoman. | | | Hell Arc??? | | - Aizu also recounts an old tale about da captains being sent to hell or whatever |

NOTES

• Perhaps Kakyo gets killed before Shunsui and Jushiro get promoted to captain?
  • Shunsui says “But I hadn’t been able to kill Tokinada back then,” so this might be before they achieve bankai? idk prob not
    • It could be implied that he didn’t have the power or status to kill him
• Shunsui finds out that Nanao’s mother died after they have graduated since in the flashback (Chapter 652), both Shunsui and Jushiro are wearing the regular Shinigami uniform and not the academy uniforms.
• After Jushiro and Shunsui’s graduation and before Nanao’s enrollment, the Kido part of the curriculum was added.
  • Before Yoruichi, Rose, Shinji, and Kensei are Seated Officers?
• [In Rebirth of Souls Bleach game] Jushiro set up the ceremony and called the whole squad for Kaien’s wedding. Shunsui even visited.

present year is 2001 CE

I’d want her to recognize Tsunayashiro — as in both were students at the academy at the same time? or met in noble circles?

Erigawa could be a clan that’s apart of the Central 46 maybe??? or is just a high aristocratic family like Shunsui, but instead of being from a long line of martial artists, she’s from a long line of kido users?
