Tsugunaga Momoko is a key member and product of the Berryz Workshop. She has been fashioned as a musical idol and in my eyes she is ready. At the tender age of 16 she has already perfected the act of an adult acting like a child. This may have the effect of looking like a child acting like an adult but I still prefer the idea of the twofold convolution. My reason being is that a key to the success of a number of adult musical idols in Japan is their acting like children. They affect child like ways to garner our support. Momoko has this act down already. When she is fully grown she will be able to exercise it with prodigious skill.
