Welcome to Japan, Ms. Elf!

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 are enjoying life in both the fantasy world and Japan. They go to look for magic stones in the blazing heat of the Ujah Peak ruins.

Life in Japan continues to surprise and delight Marie. But when night comes, the ruins await her and Kazuhiro.

Kazuhiho and Marie have a plan to beat the bandits and stage a rescue, but the bandit boss has other ideas!
