Chihayafuru 4
The opening transition reminded me of the Forest Gump feather scene:
(Also, cherry blossom petal hnnnnggggg).
As for the transition from Chibi-Chihaya to Supermodel-Chihaya, I'm not quite sure how to take it, because now everything has sexual or at least romantic subtext. Forget the random glances and comments, now you have tackle hugs to deal with... and all that means is that the potential for it to become "jdrama the anime" is very high, but I'm going to hold out hope that Chihaya doesn't become the shitty shoujo heroine stuck in a love triangle sandwich between moody emo boy and jerky friendzone guy.
Also, since anime gaf is all about teams an shit, I'm declaring
Team Arata to be the only team worth joining. Because Ta-kun is a horrible, horrible person.
