Average salaryman Kitase Kazuhiro's hobby is sleeping. In his dreams, he visits a fantasy world where he adventures with an elf he's befriended named Marie. But one day when he wakes, the girl he's only seen in his dreams is there beside him!
Kazuhiro and Marie enjoy a day in Japan. Later, they theorize that they'll be able to return to Marie's world if they fall asleep together. That leaves just one problem—they'll wake in the same place they left, with an angry Arkdragon lying in wait!
