Being a ghost, he has quite a spooky appearance at first. His eyes are dark brown, almost black and slightly soulless once he was killed. His hair is white, it looks like it should be straight and neat but it’s slightly messy at the ends. But once you get to know Rei is just a playful kid (15 years old) that you accidentally killed. He talks to you because you’re the only one that can see him and doesn’t really blame you for your actions. You and him end up being more like friends.
