Here is a short report from Japan Expo 2012 in Paris.
Apparently, Yokoyama, Tonooka, and Tachibana came first on Thursday. Took a walk around the venue and appeared on Niconama.
Asahi and Endo followed later on Friday.
They performed S.O.W, Don't think Feel!!!, and MAMORE!!!, also for extra
they performed a song from Evangelion A Cruel Angel's Thesis. All are
scheduled to be airing as part of collaboration with CosCosPlayPlay on
BS SkyPerfect on July 16.[ref]
After it, they did a handshake session.
There was no signing session but somehow a British idolinger got signed Yokoyama T-shirt and a Belgian idolinger got one signed Endo T-shirt and one signed Tonooka T-shirt for his mom who's also an idolinger :)
