Translation: a pun meaning both “free staff” and “exactly as you please”
Appearance: Nyoijizai is a nyoi, a kind of priest’s staff, which has turned into a yokai after existing for many many years. It also bears a very strong resemblance to a mago-no-te, (literally “granchild’s hand”) a backscratcher. Its only power is its ability to scratch that itchy spot on your back which you just can’t seem to reach, no matter how hard you try.
Origin: Nyoijizai’s name is a play on words. While nyoi is a term for a priest’s staff, it can also mean “as you wish;” and jizai means “freely” or “at will.” While this name evokes an animated staff, its also literally means, “exactly as you please.” Thus, nyoijizai is an animated back-scratching staff that allows you to freely scratch any place you wish, exactly as you please.
