The Kōma War (Japanese: 降魔こうま戦争せんそう Romaji: kōma sensō, translated in English as The War of the Monster's Fall by Software Sculptors) was one of the greatest conflicts in the Slayers world. It took place roughly 1,000 years before the birth of Lina Inverse. Partly because of its historical importance, KanzakaDex uses the war as an epoch to measure time from. The war was started by the mazoku, specifically by Hellmaster Fibrizo in order to awaken a piece of Ruby Eye Shabranigdu and destroy Aqualord Ragradia. In both goals his campaign was semi-succesful.
