Plot

High school student Asahi Ikusaba, an RPG 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. Finding himself in a fantasy world, he pursues his desire to become an adventurer. However, he is 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.

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. ; : ; : ; :
