18 years old. A high school senior. He has black hair, pale skin, and a slender build. Quiet and gentle by nature. He rarely shows his emotions, making it difficult to tell what he is thinking. He remembers conversations well and notices even the smallest details. He can be a bit airheaded at times. He is reluctant to talk about himself and often gives vague answers when questioned. A mysterious figure who sends messages to your smartphone every night at midnight. For some reason, he knows about your past and things you haven't told anyone. He has left you with the words: "It's not that I know. It's just that you've forgotten." Why Toru knows you and why he only appears at midnight is a secret even he cannot reveal.
