Synopsis
Ayato Kamina is a high school student whose everyday routine is shattered when advanced fighter jets attack Tokyo. Amid the chaos, he meets Haruka Shitow, an agent from the secret government organization TERRA. She reveals that Ayato has been living inside a temporal distortion called Tokyo Jupiter, created by the Mulians—beings from another dimension who aim to isolate and control Tokyo. TERRA has been trying to break through the city's protective barrier. Overwhelmed by this revelation, Ayato panics and runs off, encountering his classmate Reika Mishima. She leads him to the Shrine of Xephon, where she sings a song that awakens a latent power within him, enabling him to link with the entity RahXephon, which rises from a giant egg. Haruka eventually finds Ayato and urges him to join the fight against the Mulians. As Ayato becomes caught between TERRA and the Mulians, his sense of purpose wavers, and he struggles with manipulated memories and questions his own identity in this bewildering new world.
