Ms. Sanada is a catgirl and the chief head maid of the Valhalla Royal Family, serving as one of the main characters in UFO Ultramaiden Valkyrie 2: December Nocturne. She originally came to Earth after Princess Valkyrie left her home planet, driven by her deep devotion to the princess. Her background is rooted in her role as a loyal servant of the Valhalla household, where she oversees other maids and ensures the princess’s well-being. In terms of personality, Sanada is fiercely dedicated to Valkyrie, to the point that she is described as a Valkyrie fundamentalist. She is extremely supportive of Valkyrie’s romantic relationship with Kazuto Tokino and often goes to great lengths to protect or promote that bond, though her well-intentioned efforts sometimes backfire and create additional complications for the group. Her primary motivation throughout the season is to keep Valkyrie safe and happy, which ties directly into her role in the story as a proactive member of Valkyrie’s entourage. When a mysterious figure known as Valkyrie Ghost appears and a series of strange events unfold—including the activation of the Key of Time and the emergence of twelve black moons—Sanada takes initiative by contacting Mehm, a fellow ally, to investigate a certain legend of Valhalla that may hold the key to the crisis. Her actions help advance the search for answers and contribute to the group’s efforts to confront Valkyrie Ghost and uncover the truth behind the phenomena. Key relationships include her unwavering loyalty to Valkyrie, her collaborative bond with Mehm, and her interactions with the other catgirl maids and residents of Tokinoyu Bathhouse. While she does not undergo major personal transformation in this season, her dedication remains constant, and she is present during critical moments such as the confrontation with Valkyrie Ghost and the resolution involving the Blizzard of Time. In terms of notable abilities, Sanada is depicted as a capable catgirl maid with the physical traits typical of her kind, such as cat ears and enhanced agility, though her primary strengths lie in her organizational skills, knowledge of Valhalla’s customs, and her unwavering resolve to serve her princess. She also demonstrates a susceptibility to illusions, as seen during a blizzard incident on Nekomimi Hakkouda Mountain, but otherwise remains a reliable supporting presence throughout the series.
