Welcome to Japan, Ms. Elf!

Ever since Kazuhiro Kitase was a child, whenever he slept, he would dream of a fantasy world. One day, he explores the fantasy world with his elf friend, Marie, but they get killed by a dragon. They abruptly wake up in his home in Japan and they eventually work out that whenever he falls asleep or dies in the fantasy world, he and anyone he is touching are sent back to Japan, then they can return to the fantasy world by falling asleep. They regularly go back and forth, with him helping Marie adjust to life in modern Japan and then going on quests in the fantasy world and eventually bringing others back to Japan. ==Characters==

; / : : A 25-year-old Japanese salaryman who since his childhood habitually shifts into a fantasy world when falling asleep on Earth. In the other world, where he calls himself Kazuhiho (due to a childhood spelling mistake) and ages much slower, he is still 15 years old and an Illusory Swordsman who is traveling with Marie. It is only after he and Marie are fire-blasted by a dragon and Marie unexpectedly appears by his side in Japan that he realizes that the other world is real and his shifting ability can be extended to others. Among his special skills in the other world are the ability to create illusions, to travel through another dimension to cover distances with speed, and a plethora of languages he picked up. However, except for food, he is not able to take any items to either world during his shifts. He falls in love with Marie as the story progresses. ; / : : A 102-year-old Elven Spirit Sorcerer—a mage skilled in both arcane and spirit magic—and a longtime adventuring companion of Kazuhiro after she had killed him on their first meeting. While they intrude on a dragon's lair to have a look at its eggs, they are discovered and blasted with dragon fire. When Kazuhiro hugs her in an attempt to shield her, he inadvertently takes her back to Earth, where she becomes enamored with most of the novelties found in its culture, particularly the food. In time, she also falls in love with Kazuhiro. A running gag throughout the series involves Marie playfully commenting on Kazuhiro's sleepy looking face, much to his chagrin. ; : : An ancient female Arkdragon who can adopt a near-human form by transplanting her consciousness into a body regurgitated from her draconic self. When Kazuhiro and Marie intruded on her lair to take a look at her eggs, she took offense and killed them both, which resulted in Marie getting displaced to Earth along with Kazuhiro for the first time. After the two return, they manage to pacify Wridra with an offering of Japanese food and malt beer; and after taking a fancy on these delicacies, Wridra initially pays them with her own scales and blood (which are extremely powerful and rare magic components) and later decides to visit Earth as well. ; : : A young cat beastman and a member of the Neko Tribe who was living with his grandfather in hiding ever since their tribe was decimated by a monster, which was looking for magic stones the beastpeople had mined and which it was guarding, and subsequent human persecution. Captured by some bandits, who also killed his grandfather, he is forced to use his grandfather's magic stone to summon monsters for waylaying travelers until he is freed by Kazuhiro and Marie. ; : : A sociopathic mage with the power of prophecy. Also known as the Twin Blade Magic Swordsman. While renowned for his prowess, he is also infamous for his unstable personality. When Kazuhiro and Marie discover a new, unexplored labyrinth, he becomes consumed by jealousy and puts all his efforts into a string of attempts to thwart them. ; : : A young librarian and acquaintance of Kazuhiro who lives in the same apartment complex, and takes an immediate liking to Marie. ; : : Kaoruko's husband. ==Media==
