Onnakishi-san, JUSCO Ikou yo

A high school student in Hiraya, Nagano Prefecture, discovers a princess and her knight unconscious in a rice field during a storm. They fled their homeland after an orc invasion using gate magic and set up a temporary government at his home. Tensions arise with a childhood friend who has feelings for the protagonist, the knight's curiosity about modern Japanese life, and the presence of a substance called superdense Rinichirounium. The story blends slapstick humor with otaku references in a rural setting as characters from both worlds begin to interact.
