An actual good (isekai) horror story? Count me in. Pretty easy read. Not a complex story, but it is well structured, well paced, and quite claustrophobic. Hell, this was a nailbitingly exciting read. Is this a masterpiece? Nah, not even close. This is not where you will decipher the meaning of life. It is just an easily digestable horror, which gives you some cheap thrill. [As a note, the storyline strongly resembles the western teen horrors, so prepeare yourself for the "to be continued" aftertaste] The characters are fine, nothing fancy, but they were interesting and sympathetic enough to make me care about them. Therefore, itwas able to maintain suspense, unlike lot of other horror story.

All in all if you feel like you want to read a popcorn horror to kill some time, then I definietly recommend it.
