This Enma is wasn,t sarutobi monkey, it’s the monster with black flames that the Hell Realm Pain the one who fight Konohamaru and Ebisu uses to judge if a person is telling the truth.Also, Enma is the jutsu which rips out your tongue. I transed what the spoiler guy said. The monkey is also called enma so the jutsu is probably no called enma though it clearly is a version of the Japanese legend of 'enma' so the spoiler guy just calls it enma.
