Actually, in the Music Star, the babies are from V2, the toddlers are clumped, the teens are clumped (two of the boy teens were from the V5 Celebrity!), the adults are clumped, and two of the Seniors are clumped. There are only four new charachters. They are Rextchi(Senior), Dreamtchi(secret charachter), and Dazzletchi(secret charachter).
And Kuromametchi's dad is under Kuromametchi's description and picture.
