I heard Nachu's more of an MC so if/when she does start showing up, it'll probably just be in that capacity. She probably won't sing or be on stage that much and maybe it's for the best since I don't if Japan could handle so much woman!
And it's funny that you mention a ****ty pornstar...
Before
Tezuka Machiko joined the group, she was known as Harada Ourei and was a very, very, verrry busty Gravure model.
Seriously, the more I learn about the group, the more I think they could be a lot of fun.
