Sano just leaned back in his chair, watching the robot. The song...it really was pretty. That little robotic twang to Kaito's voice...just added to it, in the Aeon Clock's opinion. For now, he was content to just listen, eyes sliding almost shut. He was unaware of that...peaceful little smile that had snuck on to his face. Beware, Kaito. Seeing Sano open has a price. D:
