ChibiChibi

ChibiChibi is a mysterious child, who, as we later learn, carries an incence burner which contains Princess Kakyuu, the lost princess that the Sailor Starlights search for. ChibiChibi transforms into Sailor ChibiChibiMoon, and helps Eternal Sailor Moon defeat Galaxia, the final villain of the series. ChibiChibi is actually a piece of Sailor Galaxia, also knows as the "Light of Hope". In the manga, ChibiChibi transforms into Sailor Cosmos, who comes from the future. She traveled to the past to guide Eternal Sailor Moon and help her destroy Chaos.
