The Kekkai (結界) is a net-like energy barrier, established by the Great King Yama, that divides Demon World from Human World, resting in the pseudospace. Only demons below A-class can pass through it. A more powerful net was going to be made, but net energy was the energy most easily spread, to cover the distance in the pseudospace.

HistoryEdit

It was cut down by Kazuma Kuwabara, and his newly-developed Jigen Tō, while chasing Shinobu Sensui along with Kurama and Hiei, to Demon World during the Chapter Black Saga.
