1. Thank you for informing us.
2. Who would voice Hinata and Kaoru and what/how would they sound like? Granted, reading this manga, I'm pretty sure us readers are now used to the fact that both siblings are crossdressing, but I'm still curious nonetheless. Hinata wouldn't be too hard, probably, but who'd be able to voice Kaoru? Because iirc, those that ain't close to him wouldn't recognize the fact that he is a guy based off their initial impressions of him, which leads me to believe that, despite his age, he at least sounds androgynous enough to pass as a girl.
