Another of the eight princesses of Valhalla. She makes a brief appearance in the first series, and is not seen again until the final episode of the third series. Apparently she leads a sort of anti-pirate space fleet and she spends her time hunting down corsairs, criminals and such. She discovers an ancient artifact of Vahalla called the Princess Mural, in which past generations of princesses have had their weddings in front of it. She brings it to Earth so Kazuto and Valkyrie can be married in the same tradition, but that also causes the space pirates to come after it.
