It’s official: I no longer have any idea how I first found this.
That’s Wagamama Rakia (Twitter). They’re new. Like brand new. Like “first performed at Freedom Nagoya over the weekend” new (I’m not sure if that’s true). While not exactly ground-breaking, just this one video shows more overall competence and intent than many an idol who comes over to the hard side.
They actually have a little stream player on their website; just scroll down a little, and it’s on the left. I’ll assume that those three tracks are the first single, and you’ll take me at my word because who’s to say that I’m wrong, and then we’ll all go blissfully into the night, ignorant as hell and still humming along to that chorus.
