HAIR THREAD!
It's nice not to have the characters with the same hair styles all the time, but seriously,
three of the girls (Hitagi, Tsubasa, and Tsukihi) with the exact same medium-short haircut? That hardly seems coincidental.
On the other hand, I actually like Nadeko's new hair style. It's very feminine and it fits her well. Don't know why others are averse to it.
I'm looking forward to this. Can someone give me some hints as to what the plot is about?
