If only some otherworldly demonic force would burst through the earth's crust and drag some of the tepid, lifeless, manufactured popstar pap away from our screens, newspapers, and lives...

Perhaps thoughts like this were going through the team at Nitako's collective minds as they sat down to discuss the plotline of their latest outing - and sequel to Save Toshi - Popstar Physics.

Demons have kidnapped cutesy anime popstar Toshi, and without her devil-slaying dance powers to protect the world, a zombie apocalypse has ensued.

Popstar Physics unsurprisingly serves up more of the same Save Toshi-style action: you're tasked with shooting balls around to destroy zombie clones of the unfortunate pop princess.

No, not Britney Spears.

Popstar Physics will hit the App Store later today, and will be free for a limited time.

Justin Bieber had better watch his back.
