As a result of an unfortunate fall from a bicycle, a girl named Yuno received a serious head injury. She generally loved to drive and not on city sidewalks. The heroine was fond of mountain tourism and overcame mountain paths on her special bike. During the next trip, she fell and hit her head on a stone. The wound seems to be small, but the blow caused memory loss and now the girl does not remember her past, friends, and even her name. This can take a long time, and she does not want to wait, so she began to look for a way to quickly restore her memory. Doctors shrugged, but one healer advised to go to the shadow monsters. They store all the memories and if you collect them, you can regain your old life again. Help the heroine in Miss Yuuno.
