My name is Kaguya. In an instant, I went from being a regular high school student to a savior princess. Now I have been driven into another universe, where fate binds me to its salvation. I find myself traveling with a beautiful woman named Bambi and Gold, a strange, expressionless doll that protects me at any cost. Both of them are supremely skilled in what they do, yet I feel utterly useless! I was hoping to befriend Bambi and prove my worth during our travels, but I cannot seem to find a way to make my mark. Along the way, we meet the wise Waseda, who ironically is from my world. Can he help me fulfill my given destiny and find my way back home?

Kaguya
Kaguya was found when she was very young, looking like a war refugee. Adopted by the Haruyamas, she grew up loving her family but still feeling alienated without the knowledge of her past. Her life is again thrown into chaos when her father is arrested for embezzlement, and then again when she is confronted by Gold with the truth about her past.

Gold
He is an android replica of Kagami, the boy from Kaguya's dreams. With a skintight metal outfit and gold whip, which Kagami used to wield, Gold has been sent to protect Kaguya. He is typically silent and willingly does anything Kaguya says. Sometimes however, Kagami's personality takes over the android, and in those moments, Kagami remembers Kaguya.

In addition to Planet Ladder, Narushima Yuri has also created two other epic-in-scope manga series. Shounen Mahoushi (The Young Magician) tells the story of a magician and demon at odds, but still friends, in the wake of other mystical forces that want them dead, and Genjuu Bunsho is a science-fantasy adventure of two men sent to unravel the secrets of a new society that came into being after the near-end of mankind in a cataclysmic meteor shower. Yuri based the beautifully illustrated, galaxy-spanning saga Planet Ladder after an old Japanese fable, Kaguya-Hime (Princess Kaguya).
