Once upon a time in the small town of Hiraya, Nagano Prefecture, lived a normal high schooler named Rin Ichirou.
One stormy night, he found a Princess named Pau and the Female Knight (Valkyrie) who served her, Kurauzera Rou Kotovic, collapsed in the middle of paddy field.
Both of them had escaped from their country which fell to an Orc army attack using Gate magic.
And now they established government in exile at Rin Ichirou’s house.
Between a jealous stalker childhood friend, Princess Pau and Krau’s fascination at Japanese modern technology and culture, and super dense Rin Ichirou, 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.
