Here is the bonus “parody” manga that was published in the back of the Sailor Moon Materials Collection. Translations are available at Kurozuki.
While very short, the story is quite wacky =) The name of the story comes from the idea that this is a parallel (or alternate) future timeline in which Usagi has had a second daughter after Chibiusa (Takeuchi Naoko has stated clearly that Usagi will only ever have the one daughter in the canon story). This character’s name is Tsukino Kousagi, and she is “Parallel Sailormoon”. The characters on the first page are the inner senshi grown up. The young versions of Makoto, Minako, Rei and Ami that you see in the bottom panel on the second page (back of their heads) are their look-alike daughters.
