"The Royal Guard, the Zero Division, confronts Yhwach as he attempts to enter the Royal Palace.
However, the King of the Quincy and his Schutzstaffel break through the Zero Division’s overwhelming Bankai and finally step into the Royal Palace.
Entrusted by Ichibē Hyōsube with the protection of the Soul King, Ichigo Kurosaki and his allies take on that duty.
But due to Yhwach’s scheme, Ichigo ends up cutting down the Soul King with his own blade.
The death of the Soul King—this signified the collapse of the Three Realms.
Distortions begin to appear across each world, and signs of destruction start to spread throughout the entire world.
The Gotei 13 join forces with the remaining Quincy and head toward the Royal Palace.
However, the Royal Palace has fallen into the hands of the “Wandenreich” and has transformed into the Wahrwelt Castle.
As if mocking the Soul Reapers, the castle towers high in the sky, where the Schutzstaffel lie in wait.
Across various locations within Wahrwelt Castle, fierce battles unfold between the Gotei 13 and the Schutzstaffel.
Ichigo learns the true intentions of Uryū, and as friends who trust one another, they renew their resolve to protect the world.
Yhwach has become a being that surpasses even “The Almighty.”
The fierce battle, with the fate of the Three Realms at stake, heads toward its conclusion.
Beyond the calamity of chaos—what awaits: despair or hope…?"
It's says yhwach surpassed the almighty. Acasual yhwach confirmed lol. Even the official English says the samething. So being soul king makes you acausal it seems
