Light rubbed his tired burning eyes and sighed in frustration. None of these files were going anywhere. He opened his eyes and realised the burning hadn't lessened. 'I need sleep..'

He smirked inside. If L thought he'd be catching Light anytime soon, he had another thing coming. 'Nobody can destroy me, for I am Kira!'
He turned to the source of the sound. "What?"
Pale lips curved slowly into a smile.
