The popularity of the Isekai story has made many people desire they could have that amazing experience. Many people have longed for themselves to reincarnate into a different world with abilities so advantageous that it can be viewed as a cheat. Rio is one of them. Rio, a salarywoman who works for a black company and is average, untalented, and overworked, is one of many who seek to escape reality and live in her own power fantasy, where she doesn't have to struggle anymore. It is a typical evening as she returns home. While crossing the street, she encounters what might be regarded as the typical Isekai narrative opening. A truck hits her! That ought to be it. Isekai tales are merely works of fiction. Reincarnation into another world is a myth created to satiate young people's fantasies; it is not real. By some miracle, she was able to reincarnate into a different universe. However, there is one issue... During her reincarnation into a different realm, an error happened. There was an issue while she was reincarnating. The fact that she is compatible with all worlds, regardless of the type of environment, has been found. As a result, her spirit was torn apart as each universe attempted to tug at it. Now waking up in another world with barely any memories of herself, Rio finally achieved her dream of becoming an Isekai protagonist! There is another problem... There are no unique characteristics or secret abilities in the body she was reborn in. Compared to the people in the world she found herself in, she is simply an ordinary person. Depressed, she initially believed that her desire to have cheat abilities would not be possible. She gave up, made the decision to live contentedly in the first village she encountered, and hoped that she would find joy in this mundane lifestyle. That is, until a retired wizard came to the village to live out the rest of his days, giving her another opportunity. All of her reservations disappeared when the wizard revealed that she had the ability to use magic. He offered to make her his pupil, and she was overcome with a burning desire. "If I don't have a cheat ability, then I'll just make my own!" It is at this moment that Rio took her first step to become the strongest. Later, she would discover that she could access other worlds where she was also supposed to reincarnate in. With the error of her reincarnation, she will exploit everything so she can become the strongest! This is the story of a girl obsessed with power fantasies and her journey to become the strongest through her access to different worlds!
