Urara survives thanks to the power of a new haircut
and also cause the biggest gut punch would be the popularity contest saving last place, creating a double whammy, two losers for the price of one chapter
Urara finally breaking and seeing what her friend's been saying about her, only to see nothing but positive things, is a triple whammy combo I wasn't expecting at all
EDIT: Koyuki being last made no sense to me, cause everybody loves an underdog, until I remember the first episode was just auditions, which also explains why Hitoe and Ritsu aren't all that high, they bypassed auditions so the audience didn't see anything from them
