The event was held at Tokyo Big Sight from July 15th till 18th, Ryubi Gundam Mascot appeared during the last 2 days when it was opened for the public.
There were showing of the anime, promotion of SD Gundam Sangokuden Brave Battle Warriors plamo kit series as well as quiz for the crowd. Visitors were allowed of course to take pictures with Ryubi Gundam Mascot.
Fans in Singapore should expect the same when Ryubi Gundam Mascot visit the country for the first time in September I suppose. ^^
