Miku and Riina are going to make their debut as the Cinderella Project's final unit, though the two are like oil and water. When their participation in the summer festival is on the line, they try to get in sync, starting with becoming roommates!
I-If I think it's rock, it's rock!

S-Se eu acho que é do rock, é rock!
