Ryoko's sudden disappearance.
Girl, a girl from Osaka.
No matter where she is, she will always be a good girl.
But who knows her loneliness?
Her father and mother rarely come home because of work. No matter where or when she is, she will not be angry, or in other words, she will not show any expression to others except smiling. I also obey what my parents say.
She will always have only one friend - Ryoko, Ryoko Igawa.
Liangzi's disappearance, the fear of darkness, when will she be able to get rid of all pain?
