Corpse Party: Tortured Souls (Remake)

One day, a group of students finds a charm called the Sachiko Charm. They participate in the Sachiko Charm "Ritual" and they all get cursed. Will they make it out alive? (Remake of Corpse Party: Tortured Souls)
I do not own Sachiko or any of the corpse party characters that you see from! But if you do, it's not my! It's Makoto Kedōin's! I'm just using the story, shifting it and using some characters, and making this book! So I repeat, any Corpse Party characters or events are not mine!
There will be boyxboy, girlxgirl, or boyxgirl shippings in this story. If you don't like either any of these shippings, don't read this! There is also graphic content, blood, death, mention of drugs, and nudity! +18!!
