As you remember the last post I posted was telling you that the new song was going to be announced on April 4th, well it was a misunderstanding, Sorry about that! The appearance of Momorio Clover Z (on Japanese TV show Bakusho Show Battle) was not them performing a new song, but it was them reenacting the Sailor Moon S opening.
If you want to watch it you can watch it bellow, hopefully it does not get taken down. As you can see from this clip they sound better than when they performed at the 20th Anniversary Event last summer. Even though they performed the song here, we still don’t know whether this will be the new theme song.
