I am Toyama Kasumi, class 1-A from Hanasakigawa Girls' High School! Today, members of Poppin' Party are having training in the basement! But, something happened when we fell down from the stairs-"Ehhhhh! Our bodies, were switched!!"This is unbelievable, but surely this is also a trial for us to let us shine! Let's do our best, Arisa♪
