Civilization Erosion (文明浸食, Bunmei Shinshoku?, localized as "Civilization Encroachment"GO) is a subconsciously active Skill of the Heroic SpiritAltera. Anything in Altera's grasp is transformed into its best form currently most suited for herself.[1][2]
"Best" does not necessarily mean "most excellent", since it is based on Altera's own perspective (her current obsession). It goes without saying what Altera is obsessed with right now. The subordinates she was expected to take along were originally horses, but turned into sheep (-like creatures) and her beloved sword, War God's Sword, transformed into the War God's Cane.[3]
