RahXephon: Pluralitas Concentio

Ayato Kamina lost contact with Haruka Mishima after a catastrophic event supposedly wiped out everyone beyond Tokyo. Three years later, invaders strike the city without warning. There, he encounters Haruka Shitow, an agent of TERRA, who promises to reveal the truth about the world. This marks the start of a bizarre chain of events-Ayato pilots a massive mecha called the RahXephon, discovers that people like his mother have blue blood, and learns he’s been living in an isolated dimension where time flows slower than the outside world.
