In this fascinating crossover. The Hundred Line: Last Defense Academy (LDA) is a grim, strategy-heavy setting where psychological stress, sacrifice, and the grotesque nature of the "Invaders" drive the plot. Teleporting the Honkai: Star Rail cast-who are used to "Paths" and cosmic powers-into a world where they must use Hemoanima (power derived from blood/life force/memories) changes everything. You will see characters from Fate/Zero, Death Note, Code Geass, Demon Slayer, Chainsaw Man, Attack on Titian and Original Characters from my own work! 8 timelines of fate in a day by day structure! A near 780+ pages of a story that slowly unravels the truth. As you read the story evolves from a 1 to 1 recreation to something truly epic!
