This is a multiverse system composed of countless parallel worlds. In every parallel world, school bullying is a common and serious social problem, and many children suffer physical and mental trauma as a result. In the real world, Ya, because she had experienced campus bullying and was redeemed, developed a strong desire to be the "light" for others. In an accident, she was connected to the fast-traveling system, thus starting a fast-traveling journey to carry out redemption tasks on campuses in different parallel worlds!
