So Mei is human? It all makes sense now. Mei is just a victim of the curse. In order for the class not to die they all had to ignore a student, and now that Rei-kun has made contact with the classmate that “didn’t exist” he will as well be ignored so that the curse will stop. But still, Mei-chan would be easily mistaken for a ghost because of her weird looks and behaivour. I must admit, I too thinked she was a ghost up until now. I suppose Rei and Mei both don’t exist now hehe. I am a bad person for making this joke but Now that Rei is being ignored like he wasn’t there he can pretty much do whatever he likes during schooltime (like peek under girl’s skirts? 😛 ).I wonder what Rei will do next. As the protagonist he will probably go against all this and try and stop this curse once and forall. I feel kind of bad for him. He wasn’t informed about this whole story and his curiosity just drove him to do all theese investigations. His classmates are to blame for all of this!
