NOTE: Like the other music oni, there’s a number of things mixed up in this name. “Kangakki” means wind music instrument, and aside from replacing the “ki” (instrument) with oni, “kan” (pipe) has been replaced with “divine/god”. Its name is “Fagodd Finger”, which seems to be a mix of a bassoon (a wind instrument) and the God Finger finishing move from the Gundam series.
Yes, there’s a simpler name that we are avoiding for obvious reasons.
