This is EMU’s first game since 2005, inspired by their previous work Kimi ni Tomoru Hi. As a result of a request from a distant relative, Masato became the manager of the orphanage Yuriorien. He didn’t know that it was located in a remote part in the mountains and began to regret his decision, but he was soon taken in by the warm hospitality of the people in the orphanage. Thinking that it wouldn’t be bad to work in a job where you were needed by others, he began to live with the girls who all had their own peculiarities. At that time, the girls still had not realized the dark side which lied within their hearts.
