Rei's Idol persona, Mars Reiko, seen exclusivley in the live action drama version of Sailormoon. This is her debut outfit, seen in episode 23. One of my fave episodes of the series, it's when Rei awakens her senshi powers, and we also get to see how adorable Rei-chan is at being so awkward at taking part in fun activities
I think Ms. Kitagawa Keiko does a tremendous job playing Rei, and in this episode is especially cool as Sailor Mars. I really like how you see her grow both into the role and grow in her acting as the series progresses.
Doesn't matter what medium Sailrmoon is done in, it's always Rei-chan FTW!
