It's very nice I love it. In first the episode 1 is not so scary but When the next episode start more and more scary it becomes. The last three episodes means 10,11 and 12 are most scary. In last episode what a shoking truth it was about the extra one. And what a terrible curse of class 3-3 in which each and every student die if it is not solved quickly. It will very scary and sometimes funny but Watch it sure.
