One winter day, at school, Natsume noticed a spirit floating around Kono. She had flowing white hair and red eyes; an albino, Natsume observed. The spirit chattered, unheeded by the fact that Kono seemed to be ignoring her. Except, for the slight upturn of her lips.
Kono was smiling.
Natsume was surprised. For someone who pushed away spirit and human alike, this yokai had manage to bring what was undoubtedly a small smile to Kono's lips.
From then on, wherever Natsume saw Kono, the albino spirit was with her. It seemed to chatter often, though occasionally Natsume could see a quiet expression of sadness on the spirit's face. Every now and then, he could see it in Kono's eyes too.
