YES! YES! And one more YES!
I like Mikuni's songs, clips and her personality very much!!!!!!!!!! She has my love with the same power as Ayu
I don't think she's underrated - she's just not so rich and popular as Ayu is.
My favourite song of Miku is Sore Ga Ai Deshyou from FMP?Fumoffu opening!!!
The best song of all times and nations as for me
And Miku, I think, has a great potential!
