Cross the pirates and open the world's treasure

[Multiverse Travel • World Devouring • Crossover Powers]
In the world of Kamen Rider Gaim, power comes from the mysterious Helheim Forest, a parasitic realm that invades other worlds. It absorbs their energy and produces Helheim Fruits, eventually culminating in a Golden Fruit that grants godhood to whoever eats it.

But what happens when the Helheim Forest invades the One Piece world, a universe where power also comes from mysterious fruits?

Two power systems collide.
One born from Devil Fruits, the other from Helheim.
