Devil gates, or Demon gates (「羅城門」?; rashōmon; demon castle gate) as they are sometimes called, are demons' strongholds[Citation needed] that look like ruined arches surrounded by foxfire with a sinister glow. Similar to Demon Scrolls, Devil gates are also color coded, however, they vary in appearance. All Devil gates are immobile and when they are defeated, they disappear forever. Amaterasu is also unable to escape from any Devil gate battles. The demons in a Devil gate are always stronger than those encountered in in Demon Scrolls and appear in a higher quantity.
