What I don't understand is why Aqua feels the need to disguise in order to help them? Is he embarrassed, does he think they wouldn't accept help from him? Oh, or maybe he's doing it because Kana has been avoiding him lately. That might be it.
kana's really cute and talented, but her own inferiority complex fucks with her mind too much add to that the fact that she almost drowns herself in her own melancholy and she'll never move foward in a state like this
