The main focus of the 2013 Rozen Maiden anime is on a Jun who didn't wind the key, in an alternate universe from the one who wound the key. In several points in the show, these two universes cross paths and are linked via N-field.
My question is, is the universe in this TV series where Jun wound the key the same world/story/canon in which the original Rozen Maiden took place (or even "Träumend")? Or is this just part of a completely different storyline/canon in which there was a Jun that wound the key and the events in that universe were similar but unrelated to any of the previous series?
