Is there any character in AB that u don't particulary like?

Not really. There are characters, like Takeyama, Takamatsu and Fujimaki, whom I don't dislike, nor like. But, the rest of them are simply awesome and I could rave on about them for days on end... I'm not going to do that, though. XD

Nope, I thought they were all pretty likable characters.

I dislike Yui and Tenshi. Tenshi had almost no personality but she had depth. The writers just didn't utilize her potential well. Yui was desperate for love and that annoyed me but I can't hate either of them because they had genuine reasons for acting the way they did. Welp.
