This post contains spoilers. If you have not seen the episode then it will probably ruin the fun. You have been warned!
Dammit! I knew it, I predicted it! This is all Mei’s fault. Apparently the curse “has started”. Diffrent people from class 3 will start dying, as well as their relatives! The dots are all connecting, its all starting to make sense! It seems like the one who caused it was Rei himself. Probably because he interacted with something that “doesn’t exist”.
It seems the 2nd incident has heappend. Just like the other one, Rei was indirectly involved in this one. Just that, this time he manages to save his classmate. Now Rei knows for sure that this is all real. This is more than just an myth. Seeking more answears, our curious protagonist seeks Mei in the dools shop. Once again, she appears next to the doll that looks just like her. She will apparently not come to school because she doesn’t feel like it. Again, he has been warned about this by Mei herself!
Rei finding out about all theese things is not good at all. In fact, he probably is the one who caused it. This was probably caused because he has been talking and hanging out with
“someone that doesn’t exist” therefore causing all theese deaths. Also, he is a witness in all theese “accidents”. Coincidence? I think not.
