Highlights:
A thousand years ago, the original Thirteen Court Guard Squads consisted of ruthless and barbaric killers without shared purpose. They partook in slaughtering the Wandenreich, and Yamamoto and Sasakibe personally defeated Yhwach.
Afterwards, Yamamoto adopted a peaceful philosophy and formed a unified Court Guard system.
Back in the present day, Yhwach bisects and disintegrates Yamamoto. Ichigo breaks free, and Byakuya asks him to protect the Soul Society. Ichigo trades blows with Yhwach's Reishi Sword using Getsuga Tenshu, but is quickly defeated.
Yhwach attempts to stab Ichigo in the neck, but is countered by a defensive Quincy technique called Blut Vene. Yhwach reveals Ichigo's mother was a Quincy, making him part-Quincy, which allowed Ichigo to break Quilge's Jail and unconsciously counter Yhwach's attack.
Shadows appear to transport the Quincy back to Silbern and Yhwach realizes that Aizen used his shikai on him to lose track of time. Ichigo tries to approach Yhwach, but his Zanpakuto is destroyed by Jugram.
