Katou Emiri has been having her teeth straightened for a few months now. I think it's showing more and more.
She certainly seems to be smiling more broadly now, anyway.
I have admired her work at least since Candy Boy, and especially in Baka to Test to Shoukanjuu.
But a poster on 2channel said that he had never really noticed her work, but admired the way she responded so forthrightly when the rumor of her orthodontic treatment came out last spring.
At the moment, Emirin is in two anime: Kuroshitsuji II (as Meirin) and Seitokai Yakuindomo (as Kaede).
The little photo of her below with Tatsumi Yuiko (left, Riko in KissxSis) and Matsuki Miyu (right) is from publicity for a new "media mix" project called "Aka-Pro" ("Akarui San Shimai Project"). They play the "three cheerful sisters" in the title.
This is based around a radio show in which the three do little plays, as well as standard radio talk.
The media mix is with Comptique and CompAce magazines, and a website (still in preparation, link from here). And who knows, an anime might come someday.
