Sorry I didn't get back to you earlier--I had a problem with the message function that's been going on for the past few days for some reason. Perhaps you've experienced it too.
Anyway, Nana is indeed adorable, and so is Mayu. Nyuu is adorable as well, of course, and the whole relationship she has with Kohta is really cute. Yeah, Lucy only gets awakened when Nyuu gets hit in the head. Bando would have killed her in episode two, had she stayed as Nyuu for sure.
I've always liked anime too. I can't say I've ever watched Naruto, but I like shojo anime like Utena, Sailor Moon, Rose of Versailles, Chobits, Princess Tutu, and other anime like Ranma 1/2, the Dragon Ball series, Chrno Crusade, Elfen Lied, Heidi.
