本当はこわい話 かくされた真実、君は気づける?

Short stories with a twist, good for learning but that's it.

I couldn't find the stories interesting enough to keep going. Probably because their length, you can not get as invested as with for example 世にも奇妙な商品カタログ, which concept wise, is very similar, although a worse version in my opinion.

Basically they are very short stories with a twist, 2-5 pages. The first volume contains a short introductory manga, and 31 short text stories. After each story there's a page from the "librarian" after each story that gives some insight onto the story you have just read.

Learning wise, I think it's very good if you can keep reading, as there's a big variety, and they are quick reads.

One note though, don't buy the digital version if you use an e-book. The page where the librarian gives her insight is an image, and a pain to navigate. That's over 31 pages that you are going to have to struggle to be able to read.
