Ryouseirui (両声類) literally translates to "both vocal species", and is a Japanese term to describe people who are able to sing two genders (a high voice and a low voice). An English term of somewhat similar meaning is "androgynous."
Mafumafu is such a talented ryouseirui! He can go from a male voice to a completely female one without any effort!
