The Saga of Tanya the Evil Vol. 13 — Manga Raw / Buy Official

The "devil's plan" turns out to be a savage annihilation-and-blockade scheme that all but erases the line between civilians and combatants. Tanya wrote it in war college by chasing "efficiency" to its logical extreme in a paper exercise—never dreaming she would be made to carry it out for real. The fighting in Arene grows ghastly, and the Republic's Viant resists with grim tenacity. The 203rd executes the plan as written, but its inhumanity starts to grind at the hearts of Tanya's subordinates. Tanya herself rationalizes it as "just orders" while coolly calculating the risk of a future war-crimes tribunal. This is the volume where the shortest path to victory crosses the line of what it means to be human.
