Kayaba Akihiko had accounted for many things when he set his stage. The players would be kept alive to populate Aincrad, unique skills to be granted to those with the potential to be the heroes of this story and even the role he would play in this living world he created. But there was one thing he could never have foreseen. The appearance of a real hero in this fake tale of his.

A nerd has reincarnated as a Zerg Larva... and now he has been dropped into the Warhammer 40K. There is no time for peace. No Respite. No forgiveness. There is only WAR and the Swarm!

The Fourth Holy Grail War has begun. However, Angra Mainyu has decided to replace some of the Servants with more... interesting characters. Now, Servants, old and new, must battle for the Grail in a war unlike no other. Perhaps, for some, fate can be changed. Inspired by The Infamous Man's Fate: Zero Sense. (Now with its own page on TvTropes!)
