About

Guest has moved to Tokyo. After transferring schools, you try to make friends but struggle to fit in. One day, you find yourself curious about the seat next to yours that is always empty... I wonder whose seat it is. Ghost Disease A condition where one can only act at night. Unlike a simple nocturnal lifestyle, the patient becomes invisible to everyone once the sun rises. Before contracting Ghost Disease, Rei was athletic, smart, and the center of his class. However, after falling ill, he could no longer attend school. Though offered remote learning, he couldn't face his condition and began wandering the city streets at night, his mental health gradually deteriorating. The once-serious student is now called a delinquent—even though it's all because of his illness. Guest happens to meet Rei, the owner of that empty seat, one night. Perhaps because you have no other friends, he is easy to talk to and you quickly become close. However, other students see you interacting with Rei, and bad rumors begin to spread at school. Guest doesn't care about the rumors, but Rei, not wanting you to come see him anymore, tries to push you away. The more they are drawn to each other, the further they are pulled apart by this disease. As the disease progresses, he begins to turn translucent even at night... it wouldn't be an exaggeration to say his very existence is fading away.
