High school student Asahi Ikusaba, a RPG video game otaku who has always dreamed of adventuring in another world, gets his wish when he is rendered comatose after getting hit by a car while saving a child. Suddenly finding himself in a fantasy world, he pursues his desire to become an adventurer, but finds himself outmatched by high-level monsters he stumbles across on his very first quest. Suddenly, his overprotective older sister Maya appears and saves his life. Partnering up with him, the two begin to make their way in this new world, even though Asahi comes to fear his sister's overbearing affection for him more than the various dangers this world has to offer. Characters
 
 
 A high school student whose consciousness was displaced into another world after getting hit by a runaway car. Soon after his arrival, he tried to establish himself as an adventurer, only to find that he has neither a super-high level nor any superpowers. When Maya follows him into the other world, he finds himself overwhelmed by both her paradoxically superior abilities and her smothering affection for him. Despite Maya doing all the work, Asahi ends up being hailed as the hero. Asahi's tomboyish older sister who has an obsessive brother complex, which oftentimes drifts off into a more sexual theme. After her brother's accident, she knocked her head against a wall, lost consciousness, and found herself in the same other world as him. Upon her arrival, her desire to protect Asahi bestowed her with tremendous physical and magical cheat abilities, and she makes herself his silent adventuring partner, who keeps her abilities secret from the public eye. She easily takes this arrangement and Asahi's resulting fame in stride, as her only concern in life is to keep him safe. A powerful general of the army of the Demon King. She thrives on a challenge for her abilities, but usually finds herself too powerful for most opponents. After encountering Asahi by chance—and trying to destroy him on the basis of his growing heroic reputation—she meets her match in the overprotective Maya. A clerk of the adventuring guild in the city/town of Epiphoneia in the kingdom of Caesarion, the domain Asahi and Maya end up in. She quickly becomes Asahi's greatest fan after "his" first adventuring successes. A high-level adventuring fighter, also known as "Dragon Hunter", and leader of the Clan Balmuc adventuring group.
