Yagami Taichi Wants to Do Everything Perfectly

Seventeen-year-old Yagami Taichi went to sleep, opened his eyes, and found himself back in his childhood. Though he felt helpless about having returned to his younger self, Yagami Taichi thought this was pretty good. He could relearn everything from elementary school through high school and get better grades in the future. He also planned to find a convenience store job in his senior year of high school and save up some money, so he could make a bundle from certain things later and have plenty of funds for college and his future career. After all, as someone who loved soccer, he knew the winners and final scores of some World Cup matches. But... staring at the enormous egg his younger sister Hikari was holding, Yagami Taichi scratched his head in confusion. This... this can't be right, can it? After living an ordinary life for seventeen years and making a few close friends, Yagami Taichi was beginning to feel, for the first time, that those seventeen years of his life had somehow been unreal.
