I've returned! Corrupted Memory is about "BYTE", an Operating System Artificial Intelligence (OSAI) manufactured in Japan, this A.I. is very human, it can feel emotions, it can feel sensations, everything that makes someone human. In this song, BYTE gets a virus attack, but not just any virus, a very lethal virus, it kills him. The song is meant to represent BYTE's sudden realization of his mortality and feeling fear, desperation, pain, despair.
