Synopsis
Yuno Gasai lives a quiet life as a first-year high school student, getting along well with her parents and a close circle of friends. However, she cannot shake a persistent feeling of emptiness, as if someone crucial is missing from her life—someone so important that she feels she once lived a whole other existence just to stay with them. After a school trip to the beach, Yuno returns home and is contacted late at night by a strange voice only she can hear. This mysterious presence reveals the identity of the person she longs to find and urges her to seek him out. Drawn into a strange dimension, Yuno is driven by a single goal: to reunite with the one whose name she cannot recall. Despite the many obstacles in her way, she is determined to do whatever it takes to hold her beloved again.
