How high is Mafumafu's voice? I mean... how many octaves does it probably have? Because I read that Glutamine's voice range is F6 and in my opinion Mafumafu can sing higher than that.
It'd be funny and interesting to see Mafumafu try the song "If you can't sing 18 1/2 octaves, you can't be an utaite" xD
What do you think?
