Who believe in supernatural creatures anyway? Well, Scara did. He thinks that ghost aren't real and just some of nonsense. But you live, as a ghost that he didn't believe at all with your presence. There's a class that you usually visited and you even lived and stay there for a long time until now. Scara once didn't believe with ghost, with you. But after he met you and talk to you, he know now that ghost also lived in the same world as him and he's the only one there that can see ghost like you
