His name, Xeno Wolf, is an amalgamation of chemical elements:
His forename is derived from キセノン (read as "Kisenon"), which, in turn, is the Japanese pronunciation of xenon, a reference to Faram Dite's naming motif.
His surname, Wolf, is derived from ウォルフラム (read as "Worufuramu"), which, in turn, is the Japanese pronunciation of wolfram, which is also a reference to Faram Dite's naming motif.
