UFO Ultramaiden Valkyrie

Synopsis

UFO Princess Warukyure, also known as UFO Princess Walkyrie, follows a princess from outer space who accidentally crash-lands on Earth. There, she encounters Kazuto, who is desperately trying to keep his grandfather's public bathhouse running. Due to unusual circumstances, Kazuto ends up holding a portion of Princess Walkyrie's soul, which compels her to remain with him. However, that is not the only issue; because her soul has lost its strength, the princess undergoes both a mental and physical transformation, turning into a little child.
