Who?
Nah, just kidding
. Never been a fan of this group, but I do like Madoka OP, OreImo OP1, and Nisekoi OP2 which they sang. Even though their singing & songs are considered mediocre, at least they’re easy for the ears, unlike some anime singers/vocal groups/bands out there whose songs & vocal only brings pain to my ears. So that’s that.
