Stems from a WMG where the infamous prologue comes from a universe where Kamina was killed in the first episode, and Simon transforms into an Ax Crazy Blood Knight
as he fights the Beastman Empire. The fic skillfully portrays Simon and the Gurren Lagann
universe in a more cynical light, though it adds some great humor in the mix. YMMV, but the fights in the fic are actually more entertaining than in the show itself!
