Sailor Starlights Stage On! We are now at the Stars Arc of Sailormoon. This is part 2/12.
Sailor Stars is based off the manga and anime, with some differences. The story takes place (mainly) at the music festival. Mamoru is studying in America, leaving Usagi alone and sad most of the time. ChibiUsa comes back from the 30th Century but can't remember what happened, until she sees someone familiar....
The musical also features Sailor Galaxia, MC Fly, Sailor Animamates on planet Earth searching for True Star Seeds. They find them at a music festival...
We also meet the Three-Lights (aka Starlights) for the first time, they are searching for someone as well (Princess Kakyuu). Seiya, Taiki, and Yaten (who are the Three-Lights) are part of the music festival and join in the fight to protect Earth from Galaxia.
