One stormy night, he found a Princess named Polilyfa and the Female Knight (Valkyrie) who served her, Krauzera, collapsed in the middle of paddy field. Both of them had escaped from their country who fell to Orc army attack using Gate magic. And now they established a government in exile at Rinichirou house. Between jealous stalker childhood friend, Princess Pau and Krauzera fascination at Japanese modern technology and culture, and superdense Rinichirounium, a slapstick comedy choked with otaku culture reference in a rural Nagano countryside will begin! Also, the people from this world and from that world began to visit one after another.
