When Zero left the area with his past self’s soul in his hand, he knew he would make enemies. He knew he would make the cyber elf X sad. And most of all, the past X would hunt him down with the cyber elf. But he did not care. He had to mend this timeline, even if he would make enemies with the X of the future and past.

He had hoped that if he had told his past self of his future, they would be able to avoid it. He had also hoped that even with Weil gone, his past self would allow the humans to research on his body to create Mother Elf and remove the virus. But with the consequences now, he had no choice but to try mend it. He had to try to stir the world into the future where he came from. Even if the timeline had gone astray for a while, he needed to bring it back to its original path.
