Famitsu.com has a closer look at Lollipop Chainsaw's premium version, including larger images of the PS3 and Xbox 360 packages.
The game's standard version is called the Kira Kira Version. This received a CERO D rating, as it cuts the violence. The game's premium version is called the Zaku Zaku Version. It's rated CERO Z and has the option for the same violent expression as the overseas version.
In addition to the more violent expression, the premium version includes both English and Japanese voices.
Grashopper and publisher Kadokawa Games are including some bonus costumes with the games. These are included with the standard version:
The premium edition adds Cutie Waitress for the PS3 version and Sexy Rider Suit for the Xbox 360 version.
