When amateur chemist Haruka spills a mysterious concoction in the arcade where she works, five of her shinobi friends start acting a little wild. They think they're animals, and the only way to cure them is with Haruka's mystical Peach Ball. The best way to do that? Pinball, of course! Haruka will get the girls onto the tables, but she needs you to work some magic with the flippers and apply the antidote.
