Fullmetal Alchemist Omnibus 8 collects volumes 22-24 and features story and art by Hiromu Arakawa.

With the Day of Reckoning at hand, war breaks out in Central City. On one side, the homunculi and corrupt military; on the other, the Elric family, Ishvalan refugees, and a ragtag alliance of soldiers loyal to Major General Armstrong of Fort Briggs and Roy Mustang.

While Hohenheim confronts the homunculi's "father," Mustang finally learns the truth about Hughes's murder. Will he be consumed by hatred and do the unthinkable?
