First time i watch and listen this band i think most of them is a man and only the guitarist i think is a woman which is her name is Miko. Why i think most of them is a man because the vocalist sing with a lot of energy and with a loud voice. When i check their profile all of them is a woman. I think the vocalist in exist trace beat most of J-rock male vocalist. Here is example of their song http://www.youtube.com/watch?v=rZjlIKiCj3g. By the way Miko is very cute and beautiful.
