I've always hated anime characters like Musubi, Nodoka and Hinata.
Musubi is from the Harem anime Sekirei. Basically she's a ditzy, naive, stupid, and overly cute character. At least how she's protrayed. But here's what I think of her. She's an overly annoying, completely one-dimensional, brainless pair of walking boobs whose ONLY role is to suck out everything that's good about Sekirei. What I like to call, a Quality black-hole. I assume, she's supposed to be a likeable character because of how stupid she is, but she just comes off as annoying as hell, and worst of all, she hogs up all the screen time which could be better put to use expanding on characters like Matsu, Tsukiumi, Kazehana, even Kusano. But no, we have to put up with Musubi acting idiotic and showing us her panties or breasts. Bleh.
Nodoka and Hinata fall into the same common Trope, from Negima! Magister Negi Magi and Naruto respectively the Shy girl type. Or as I like to call 'em, "The Overrated Love Interest who never does Crap girl." I know I'm SUPPOSED, to like and sympathize with the two of them and go," Oh, they're so cute, they love Negi and Naruto from afar!" And that's okay with Hinata before she suddenly had to act like a TOTAL retard and try to take out the dude who has so far in no short order, killed off ALL of the most powerful ninja around, put the Hokage into a coma, kill of Jiraiya, AND beat the piss out of her love interest. Before she was a just a shallow if overrated character who never appears for long and is easily forgotten and ignored. Nodoka on the other hand has the bloody nerve to be both overrated AND A main character. Her power is stronger then everyone elses, she hogs up ALL of Negi's time while WAY more awesome characters like Ayaka, Chisame, even Kaede are ignored, she's a Mary Sue due to how EVERYONE seems to love her and think of her as a good person, and she has NEVER, ever had her power just go lame. She ALWAYS gets it to work.
Yeah this was a long rant, but I REALLY hate those characters.
