Review Detail of BlueCactusE in Kaidan Game Train: Abide Rule or Die!

A horror tag should be added. I rarely read horror books and might not have started this one of I'd known. I'm glad I did, though, and have read up to ch. 56. The story is a mix of mystery, horror, and a "game" forced upon the people of Earth by external forces. The MC is usually fairly calm, collected, smart, and savvy. He slowly starts to figure out what is going on, and while he will help people, he's not foolish and often acts alone. Issues with grammar are rare. I don't think there are any spoilers here, but let me know if I need to add the tag.
