The princesses of Valhalla planet.

"It's no guess. It's for reals."

UFO Princess Valkyrie is a 2002 manga created by Kaishaku (of Steel Angel Kurumi and Destiny of the Shrine Maiden note  fame) for Square Enix's Monthly Shonen Gangan, it was later adapted by into an anime by TNK that same year.

The story is about magical princesses from outer space. One of said princesses, namely Valkyrie, lands her spacecraft on the Tokino Bath House, killing its current manager, the teenage Kazuto Tokino. So in order to save his life, Valkyrie gives him half her soul. Thus the obviously adult Valkyrie is transformed into a young girl who looks and acts like a child.

Valkyrie and her fellow princesses have magical powers. So whenever Kazuto and his crew encounter any problems, she is able to transform and protect him.

Aside from causing Kazuto and his sister Rika financial problems by damaging the bath house, Valkyrie has caused problems for her sister Hydra. Valkyrie ran away because she was supposed to marry a man she didn't love. Hydra, as the second oldest unmarried princess, is going to have to marry him if Valkyrie doesn't, so she goes to Earth and wreaks havoc trying to find Valkyrie. Eventually, she is stopped by Kazuto's shrine priestess neighbor and childhood friend, Akina Nanamura, who turns her into a little girl (like Valkyrie, but with her adult mind) so she is "easier to control". Also, Hydra crashed into Akina's shrine, and Akina keeps her around so she can "work off the damage".


Akina is also a childhood friend of Kazuto and has a secret crush on him, often putting her at odds with Valkyrie. So she and Hydra are sometimes partners in crime to cause problems for Kazuto and crew.

Later, Sanada, a catgirl maid of the royal family of Valhalla, the planet whence comes Valkyrie and Hydra, returns looking for Valkyrie. She is not shocked by Valkyrie's new appearance; in fact, she finds the new Valkyrie intolerably cute. Sanada takes her mission to protect Valkyrie to extreme lengths, including, for example, turning a bunch of ordinary girls who talk even indifferently to Kazuto, into mindless catgirl servants for the Tokino Bath House.

More crazy characters come along, including prima donna/diva/ditz Laine, Cloudcuckoolander Chorus, and the intolerably ruthless "older princesses".


The show is light (mostly) in nature and is kind of a slice of life show. There are four seasons, of varying length. The second season is more serious and dark than the others, mainly because of Valkyrie Ghost, a mysterious figure who appears to Kazuto.

This is a fun show to watch for its comedic elements. Additionally, it contains many instances of fanservice. (After all, it takes place in a bath house.)

Welcome to the crazy world of UFO Princess Valkyrie, where alien (though humanoid) princesses run wild and cause mass chaos among Earthlings.

Theme songs and insert songs are by Melocure and the background music was composed by legendary composer Kenji Kawai.

The series was licensed by ADV Films (who retitled it UFO Ultramaiden Valkyrie) and later Funimation. note 


  • Ironic Hell: Essentially, where Inarba sends a character if he/she has been bad. But only for a short time.
  • Kick the Dog: Literally, seen with Little Val and Spot. Justified and averted because Children Are Innocent. Also, he's actually not a dog.
  • Knight of Cerebus: Valkyrie Ghost, contrasting with the normally lighthearted nature of the series, stops all the comedy whenever she shows up, and her true nature adds to it.
  • Leitmotif: Everybody who has a transformation sequence. Also Chorus.
  • Voluntary Shapeshifting: Laine's ability
    • Morphic Resonance: While she is a capable Voice Changeling too, the two parts of hers she can't possibly modify are her breasts (she is somewhat well endowed) and her antennae thing which is also her "weak point" since pulling it means she will revert back. These are the only things that can give away her disguise, especially when she tries to put on a disguise as a male character.
    • Glamour Failure: And if that wasn't enough, her extremely perverted and OOC behavior (by the impersonated character's standard) usually gives her away before Fridge Logic kicks in.
  • Waif Prophet: Chorus. Even though most of what she says is nonsense, she is somehow able to predict the 12 Moons of Valhalla arc.
  • World of Buxom: Out of the eight princesses, Chorus is the only one who isn't extremely ample, and that's because despite her height, she's actually one of the youngest if not the youngest of the princesses.
