From Compile Heart
If you like interesting games, put Makai Shin Trillion on your radar. It's from Compile Heart (the developer of titles like Hyperdimension Neptunia), and it stars a fallen King and a grimoire-powered girl in their quest to destroy the dimension destroying "Trillion" monster.
It'll also feature six female Demon Lords, as well as a branching storyline, and you can get a taste of what's to come in the new trailer above. Makai Shin Trillion will hit the PlayStation Vita sometime in 2014 -- a localization hasn't been announced yet.
