A Caucasian Catholic priest from Australia who learned to speak Japanese with a Kansai accent, thus giving his sentences a rather odd, humorous structure. Good-natured and helpful, he helps Mai and Naru however he can. His means of exorcism is spraying holy water while reciting the first passage of John from the New Testament of the Bible. In most arcs SPR relies on John's exorcisms whenever a human being is possessed by a spirit. In the Cursed House arc, it is revealed that John's exorcisms, unlike Houshou's Buddhist Mantras or Ayako's Shinto Kuji, do not cause physical harm when used on a possessed living creature.
