In the final episode of Gokaiger, the pirates returned all the keys to the rightful owners before setting off to the second greatest treasure in the universe.

In Gokaigers vs. Go-busters, they somehow regained the ranger keys as they used various ones to fight. In the Superhero Taisen movies, they used the ranger keys again.

How did they get these wonderful keys back in their grasp?
