"A magic barrier that the Divine Powers set up. It is based on a spiritual seal that Tenkai put up 400 years ago. The Divine Powers were able to stop the Demon Summoning Program from working by utilizing the seal."
A mystical barrier activated by Aether absorbing Jars found in the five Fudou Myouou Temples located in Tokyo. Absorbing different endless supplies of Aether from the Expanse keeps the barrier active even if one or four jars are sealed. The Jars absorb a different type based on the Seven Deadly Sins. Only when the five are sealed does the barrier go down. It prevents demon summoning, the appearance of most demons not allied to the Divine Powers, and deactivates the Terminals that run on the same technology as the Demon Summoning Program. The temples are guarded by Maitreya's Buddhist subordinates the Four Heavenly Kings and Marici.
The Mandala is activated when many Hunters were on the verge of lynching Nanashi for releasing Krishna and Fujiwara for defending him, allowing the Aztec Gods to lead raids on several districts. After they are dealt with, Nanashi goes to Midtown to meet with Tenkai, who teaches him how to deactivate it.
