This technique requires a scroll on which a blueprint of a particular area will be mapped. When activated, it causes four giant gates to emerge north, east, south, and west of the targeted area. Afterwards, the gates form a barrier around the area. This barrier has a very high durability, and anything that makes contact with it is immediately engulfed in flames. The only way to pass through the barrier unharmed is with a special seal.
- The gates are based on the Four Symbols of Chinese, Japanese, and Korean mythology. The northern gate is based on the Black Tortoise (玄武, Genbu), the eastern gate is based on the Azure Dragon (青龍, Seiryū), the southern gate is based on the Vermilion Bird (朱雀, Suzaku), and the western gate is based on the White Tiger (白虎, Byakko).
