A new scan from Shonen Jump confirms that Tales of the Heroes: Twin Brave will be getting a demo out this January, as well as some peculiar looking new attachments for the characters.
The demo, which will be coming out on January 26, 2012, will be featuring Ruca and Spada's original story. This is basically as a commemoration of sorts for Tales of Innocence R's release which will be on the same date.
In addition, the scan also confirms that the game will be getting attachments items called ??????? (Nuigurumetto). The attachment will make the characters have a sort of SD (super-deformed) chibi appearance, complete with amusing anime-style facial expressions. I'm not sure if I'm reading this right, but this will apparently be a pre-order bonus.
