To the Western world, the Vita was deemed a failure, being unable to generate enough sales compared to its predecessor. In my eyes though, it's the best portable system I've ever had. Got it since day one and it has served me well for years. Plus many of the (Japan-made) games are just my type.
Bullet Girls happens to be one of them. In a nutshell, it's kind of like a mix of Senran Kagura and the anime Sabagebu! The concept of Japanese high school girls playing with guns is nothing new, but bullets from the weapons here hurt about as much as a flick to the forehead. The only real casualties are the clothes they are wearing.
