The king Enma has an army.So,
if we do something about the prison guards, you can obtain the rock from the court.It's the proof of an Enma. I, who don't have the rod, can't even deal with the army and step into the court....Huh?and the corpse army.You will then be able to kill the king Enma, yes?My,
THAT is but a simple matter.They will obey the King no matter what.
The prison guard oni,Hmmm....It's a possibility.
Then again... We're talking as if that really was possible.
