This game is Fire Emblem meets Persona/SMT with energetic turn-based combat.
"Tokyo Mirage Sessions â™¯FE is set in modern-day Tokyo, with real-life locations such as Shibuya and Harajuku being featured. Tokyo has become beset by attacks from an alternate dimension called the Idolosphere, with beings known as Mirages harvesting an energy called Performa from humans. The story focuses on a group of young people who become allied with friendly Mirages by chance, and are recruited by Fortuna Entertainment: while outwardly a talent agency, Fortuna is dedicated to preventing invasions from the Idolosphere."
Releases this June on Wii U. Interesting to note is that it will not contain an English dub, but retain the Japanese voice-overs with English subtitles, due to its 'strong Japanese influence/setting'. Or more likely, to save money in the localization process.
