Tokyo: My Favorite Idol Is My Little Sister

To achieve financial freedom, I helped my younger sister debut as an idol. But the teammates the System matched her with were one more bizarre than the next. There was a university student determined to pass the civil service exam, who danced as if it would kill her. Could bending her waist really hurt that much? And then there was my ex-girlfriend's twin sister, a little devil through and through. I practiced with her, and while she wasn't tired at all, my back was already aching.
