Destruction looms at the end of the Thousand-Year Blood War between the Soul Reapers and the Quincies...

The Royal Guard Squad Zero confronts Yhwach as he attempts to enter the Royal Palace. However, the Quincy King and his Royal Guard shatter Squad Zero's powerful Bankai and finally step into the Reio Greater Palace. Ichibe Hyosube entrusts Ichigo Kurosaki and his allies to protect the Soul King, but due to Yhwach's trickery, Ichigo cuts down the Soul King with his sword.

The death of the Soul King mirrors the collapse of the Three Worlds, as distortions and omens of destruction start to appear in all realms. The Thirteen Court Guard Squads join forces with the surviving Quincies and head for the Royal Palace, but it's fallen under the control of the Wandenreich, who have transformed it into the Wahr Welt. The Royal Guard wait for them within the castle, ominously towering against the sky.

Fierce battles then erupt throughout the Wahr Welt between the Thirteen Court Guard Squads and the Royal Guard. Ichigo learns about Uryu's true intentions and renews his determination to protect the world together, as friends who trust each other. Yhwach has surpassed even his own ability, The Almighty...

The fierce battle for the survival of the Three Worlds approaches its end. Beyond the chaos of calamity, what lies in wait—despair or hope?
