Iwaichi is the second-most jailer under King Yama, second only to Onmyoji. Because he held several positions as an Onmyoji in his previous life and had full merit, he was exempted from the punishment of hell. He was hired as a jailer by Oniden HR's devilish methods, and then started a series of business trips (mistakes) in various worlds.
