Usui is just so boss, I can't even hate him for being contrived because he's just so awesome.
I was with Misa right up until she reverted to tsuntsun retard mode and punched Usui despite knowing that the Aoi was a boy and thus an acceptable target for violence/rape/molestation/whatever. Then again, knowing Misa it would probably never cross her mind that Usui knew the deal with Aoi just as well as she did and he was trying to deal with it his own way. I couldn't help cheering for her when she bitch slapped Aoi though as I felt he was getting annoying and it hinted that at least Misa is an equal opportunity man beater.
I wasn't so fond of this weeks attempt at a tear down of Misa though. Aoi's bitching at her for not making an effort to 'act feminine' in her free time just seems so 1950's. I suppose this doesn't mesh with Japanese culture as much but one of the things I respect about Misa is that she doesn't seem overly concerned with superficial things, at least about her self.
