Sailor Moon (美少女戦士セーラームーン) is a Japanese shōjo manga series which was really popular in Asia during 1990s and 2000s.
The five main characters are Sailor Moon (Usagi Tsukino 月野 うさぎ), Sailor Mercury (Ami Mizuno 水野 亜美), Sailor Mars (Rei Hino 火野 レイ),
Sailor Jupiter (Makoto Kino 木野 まこと), and Sailor Venus (Minako Aino 愛野 美奈子).

You can switch the "type" in "Choose A Planet" to see these beautiful planets and customize the planet with "Move The Planet".
