However, his friendship with Shizu quickly turns to fear when several spirits of the dead appear before him, borrowing her appearance. As he struggles to find the humanity in her supernatural condition, Tetsu must also face a question at once terrifying and heartbreaking:...

But when the two teens arrive on campus, they bump into Tetsu's old soccer team. Suddenly, his carefully curated life begins to unravel and Shizu may be the only one who can save him.
