IRON LEDGEROPPONENT CASE FILE
Shinji Hirako fought Aizen and Bambietta Basterbine from chapter 387 to chapter 556. Chapter 387 (episode 291): no contest for Aizen. Chapter 556 (episode 383): Bambietta Basterbine beat Shinji Hirako.
Shinji and Aizen exchange attacks, but before the bout can produce a named-opponent result, Komamura's arrival and Ichigo's return redirect Aizen into the larger battle.
Adds an interruption record, not a draw: the stopping event comes from outside the two-way engagement.
Disoriented by Sakanade's inverted world, Bambietta activates Vollständig Zofiel and unleashes The Explode indiscriminately in every direction, blowing Shinji out of the air and leaving him incapacitated.
Files W because Bambietta activates Vollständig Zofiel and detonates an omnidirectional explosion that blasts Shinji out of the sky and downs him.
