The Savita Savita Challenge is the latest trend sweeping through Japan. The challenge involves people drawing on mirrors to summon the spirit Savita, who supposedly reveals their future. For Darin and his friends, it’s all just a bit of supernatural fun—until it isn’t.

On a random day after school, the group attempt the challenge, laughing off their futures as they head home. But as Darin exits the bathroom, he manages to catch a glimpse of something no one else has seen before: the spirit’s true form in the mirror.

Mandy, the spirit, has spent countless years alone, but now she realizes that Darin can actually see her. Seizing the moment, she crawls out of the mirror, changing Darin’s life forever. Darin discovers he could communicate with Savita directly, who is now his new quirky friend.

Together, they head through the ups and downs of high school, with Savita always one step ahead, revealing Darin’s future—whether he wants to know it or not.
