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
Mafumafu hits an F6 in nibyoukan. Touyu also hits a really high note at the end of deaf room. Glutamine hitting F6 is questionable. There's a high note in rimokon but i think it's just pitch shifting, not actual squeaking.
What do you think?
