Five years after the series ended, where Zim have discovered the truth of his mission in the second year of his "mission", making him fall into despair as he decides to move out of the city to escape the painful memories of betrayal.

While Zim is moving out, he was suddenly attacked by a Lancer servant and managed to escape, where he nearly got killed and accidentally summoned the Sabre-class, especially where he was suddenly forced into the Holy Grail war where there is only one duo alive to get their wish realised, but there's more to this war then meets the eye.

A/N - I completely forgot to do this first before publishing the story... my bad! Oh well. No point in being sad about. I hope this never happens again and I... well, since it's already uploaded, hope you guys check out the story...? Thanks, my guild. Aqua out!
