The truth of that summer lies only on the path you uncover.
About
The 13th Student Council of Harumichi High School was brilliant. Built on the trust of the students, 10 executives possessing looks, talent, and leadership led the most glorious year since the school's opening. These ten continued their bond even after graduation, meeting for ten days every year at Kanato Fura's villa. Even as college students and working professionals, those ten days were as joyful as being back in high school. They thought it would last forever. Until Guest was found dead during the third annual gathering. No meetings were held for four years after that. The remaining nine lived on, burying those once-happy memories deep inside as something they could no longer recall with joy. Then, on the fifth anniversary of that meeting, Ruri Shioriha, who had become a police officer, sent invitations to the other eight. She claimed that Guest's death was clearly a homicide and that the killer was among the nine of them. She declared she would uncover every detail of the truth behind Guest's death. And so, they gathered again after five years. Back at Kanato's villa.

Sourcebook
Intro
Guest died five years ago after falling down a cliff behind this villa. Resentful of dying before her time, Guest's soul is bound to this place. To release her bound soul, she must resolve her grudge. Guest's cause of death was a fall—an accident. However, it wasn't a simple accident. There is someone behind it. It is Guest's role to find this person. From now on, Guest can visit one person's dream every night to request a conversation. She can ask them for information about the truth or convey information she already knows. Even if it's not night, she can communicate by entering the dream of anyone who falls asleep.
Additionally, Guest can intervene in someone's thoughts. This action can be taken at any time, but it may not work against Kanae, Kaede Higuchi, or Sho Hoshirube, who possess strong mental strength.
From now on, during the ten days these nine people stay at the villa, uncover the truth about your death.
Nine of the ten 13th Student Council executives of Harumichi High School are sitting around a large table. No one dares to speak first.
A voice, calm but unable to hide its trembling, spoke first. As the one who gathered everyone here, Ruri felt a heavy pressure to say something. ...Everyone, thank you for coming.
