Taking it without a second thought, Arata awakens the next day to find that his appearance has reverted to that of a 17-year-old.Arata soon learns that he is now the subject of a unique experiment and must attend high school as a transfer student for one year. Though he initially believes it will be a cinch due to his superior life experience, Arata is proven horribly wrong on his first day: he flunks all his tests, is completely out of shape, and can't keep up with the new school policies that have cropped up in the last 10 years. Furthermore, Ryou has been assigned to observe him, bringing Arata endless annoyance. ReLIFE follows Arata's struggle to adjust to his hectic new lifestyle and avoid repeating his past mistakes, all while slowly discovering more about his fellow classmates.
