Practice your Kuroba Keeper skills and send into battle! These Night Kuro feed on wishes, and are most often seen during meteor showers. Those caught in their crosshairs can be forgiven if they think the sky is falling, because fight by raining space rocks down on their opponents. Be forewarned, if you want to add one of these to your collection, be careful what you wish for. They rain space rocks down on their opponents - like flaming shooting stars. These Night Kuro are difficult to see and are super fast. Choose your strategy and go head to head with other Kuroba Keepers
