On her way to Starania, Kurai had been distracted. Now as she hovered in space before the violet sun, she was perplexed. A sun? Made out of godfire? Who or what had done this? Due to her connection with Hikaru, and in turn Hikaru's connection with Koty and recent gift from him of the ability to control God Fire, Kurai had the ability as well. This was evident in her use of her own corrupted form of god fire, that was negative, like every other type of magic or energy she came in contact with. She also had all of Hikaru's memories, and she didn't remember Hikaru making a sun. That could only mean it had to have been Koty or one of his many children.
Well, they just lost it. Kurai smirked to herself as she flew towards the sun. Stopping just a little ways away from it, Kurai spread out her wings to their fullest. Then with a quick thrash, she flapped her wings forward, creating a magical gust of negative god fire that went forth and mixed into the regular god fire. Then holding her hand out, Kurai through will took control of the negative god fire and caused it to overtake the regular god fire until the regular god fire was within her control.
Once she had control of the god fire, Kurai caused it to disperse, leaving the planet a cold charred desolate rock.
The negi then flew towards the dead-sun and landed onto the blackened surface. Because Kurai was a creature of sin, she could not restore it to life. But that meant basically nothing to her, who needed a green planet with water and all that life crap anyways? No, Kurai had other plans.
