On Naho Takamiyas first day of her sophomore year at high school, things didnt go quite according to plan. She woke up late and received a letter that was addressed to her. However, upon closer inspection, she realized the letter was from herself-10 years in the future! At first, Naho was skeptical about this strange note, but after witnessing events described in it, she came to believe it was genuine.
