The battle against Master Albert's Game of Destiny is finally over.
With destiny broken and humanity's future restored, Vent and Ashe should have returned home as heroes. Instead, a catastrophic overload from Ouroboros tears open a dimensional rift, hurling them into a completely different world known as Remnant.
A world where monstrous creatures called Grimm roam the wilderness.
A world where Hunters and Huntresses wield extraordinary weapons and powers known as Aura and Semblances.
A world standing on the edge of destruction.
Fortunately, Vent and Ashe did not arrive alone.
Deep within the M.E.G.A. System, Model Z activates an ancient emergency protocol, awakening the legendary Four Guardians of Neo Arcadia-Harpuia, Leviathan, Fefnir, and Phantom. No longer dormant fragments, the Guardians are fully conscious once again and stand beside the legendary heroes X and Zero.
Armed with powers beyond anything Remnant has ever seen:
Vent can still Mega Merge with Model X.
He can perform the legendary Double Mega Merge with Model X and Model Z.
He can now access the powers of all Four Guardians through Models H, L, F, and P.
The legacy of X, Zero, and Neo Arcadia lives through him.
Meanwhile:
Ashe retains every copy ability she acquired during her journey.
Every Pseudoroid transformation remains stored within Model A.
She possesses an arsenal of powers capable of adapting to nearly any opponent or situation.
As mysterious new enemies emerge and ancient Grimm begin evolving in impossible ways, Vent and Ashe find themselves caught between Remnant's struggles and secrets connected to their own world.
Alongside Team RWBY, Team JNPR, Beacon Academy, and the heroes of Remnant, the two Biometal warriors must uncover the truth behind the dimensional disturbance before both worlds are consumed.
Because somewhere beyond reality...
Something else crossed over with them.
And it has begun watching.
