The remaining girls all seem musically inclined and concert performances are probably what drew them to niji in the first place considering what the company had to show on the JP sidefrom what I've seen of the guys' content so far they seemed very uninterested in being there compared to the girls. Which is pretty bullshit given that they were given double the stage time
meanwhile on luxnox side you have people like luca who hadn't singed seriously at all before joining and vox who doesn't even know why he joined or where he's going with his content (not singing or dancing clearly). They're also the ones that threw a tantrum when the AR live got postponed so they might've phoned it in partly because they made them wait and they're heckin luxnox, management's favorites
