UFO Princess Valkyrie 4: Toki to Yume to Ginga no Utage

Life at the bathhouse has become even stranger now that Kazuto is living with two versions of Valkyrie at once: the mature princess and her childlike counterpart. A reunion with Valkyrie's old school friends brings back embarrassing memories and confusion when the visitors mistake the younger Valkyrie for her daughter.

Another royal tradition soon calls everyone toward Valhalla. Akina is chosen to serve as a shrine maiden for the grand farewell of the comet Sleipnir, and the ceremony comes with training, responsibilities, and enough celestial commotion to pull Kazuto and the princesses into yet another celebration that refuses to stay simple.
