I recommend you not to read this manga, unless you want to read something so awful that it's more comical than scary.

There are 9 stories, each on its own and differing in story, tension and gore. All of them are very basic and most of them are just awful, like they were written by a child, stuff like dead person calling phones and you die if you answer the call. There are few which have only alright start, but that's it, the rest turns into worse.
The art isn't bad, such style is more suitable for horror, but it's still simple and doesn't have much details at all.
Besides terrible story, you get barely existent characters. They aren't on focus because the whole manga relies on some "scary" moments to create some tension. The only chapter where I felt little bit of personality was "Christmas present", which has a good side of showing relations between father and daughter, but everything else is a joke.
Overall, there were moments with some tension, but they were mostly cheap and everything else fell flat. I guess this manga was made for midschooler audience which searches for their first horror stories. Some chapters may look like somewhat promising idea, but they feel so unfinished or the later part came on force and it was just gore instead of some event which would make the story more interesting. On the other hand... Some chapters are somewhat entertaining how bad they are. Just imagine, a paper god which cuts the people who try to steal his statue, or Santa who makes canned reindeer food from bad children. I chuckled a coule of times, if this manga had more comical (and quirky) direction, I think it would become much more interesting. The rest of horror stuff go like this: There's some legend or an event, people die, the end. Nothing more than that.
