So I've been listening to Polkadot Stingray a lot recently, and because of that me and Midel finally pinned down Radiant☆Star's subunit genres!
BL!SS: a happy mix between genki and indie rock. They fall in line more with Printemps and CYaRon's style, being a smile subunit with a pink color theme, but we decided that since Kiku is a guitarist and plays acoustic/electric, and in my head a lot of Wakana's solos are quite soft but she still has a jumpy energy about her, and Sakura's always into trying new things, having a more untraditional indie rock vibe fit them almost perfectly. Honestly Polkadot Stingray's song Ichidaiji is a great example, though they can also do harder songs like I☆ris's Re:Call and more upbeat/hardcore things like Nijimi Anazawa's character song lol
Royal Dahlia: Look no further than GARNiDELiA. Songs like Kyouki Ranbu, Gokuraku Joudo, and Tougen Renka are perfect examples of Royal Dahlia's music. A lot of EDM but with mixes of pop and traditional themed instruments, capitalizing on their mature/charming looks but completely opposite personalities. In addition, during long music breaks RD puts on 'plays,' since Mei is an actress; their first "album's" story would be about a princess (played by Mei) falling in love with a knight (played by Harura), but after finding out the knight is a woman the mother (played by Mimi) disapproves. In the end, the princess runs away with the knight while the mother only worries if her daughter will be okay and if the knight would ever lie to her again.
CandyPOP: A rap group, through and through, since Hiroko and Ayane are in it. Ayane's voice/rap style inspiration is REOL, so a lot of her songs end up falling in line with what me n Midel thought CandyPOP would sound like. Isshin Furan is a great example, with Yuyu on vocals and Aya/Hiro rapping; sometimes they do 'rap battles' with each other. Ayane and Hiroko also have different rapstyles, where Ayane is pretty fast with words and raps in mostly Japanese, while Hiroko is a little slower but incorporates more English into her verses and lyrics. All three of them sing in the choruses, but mostly the vocals are left to Yuyu haha
As a full unit, R☆ has a lot of different styles open to them, since each girl's individual styles and the special 2/2/2/3 styles are pretty varied as well ^^ For example, Marvel!Us has a very jazzy/broadway theme and feel to their music, which ends up bleeding into the R☆ third years' music, and one of the 2/2/2/3 units, TopHat, consisting of Harura and Kiku has an acoustic song because they both play the guitar ^^ (for reference it's CHICO with Honeyworks' song Tokyo Summer Session, covered by Kobasolo and Mirai; Harura sings the lower parts and Kiku sings the higher parts ^^)
Because we haven't actually tried to compose any original songs for R☆ ourself, we just kind of end up imagining what songs would sound good for them and go from there, but maybe one day it would be cool to actually make a song for them ^^ Thanks for letting me take up some space on the feed, hope you enjoyed this little blurb about R☆'s subunits!
