I really enjoyed this work of art. The story is full of plot twists. It's not just an ordinary survival thing. If you are action/horror/suspense lover then I guarantee that you will enjoy this. I'm not really a person who keeps eye on the art in manga or anime so I can't really comment on it. But I really did like the way they made the masks for the masked people. There are lots of characters but mainly supporting ones. There are bad and good people and you might fall in love with how brave some of them are. I was excepting it to be maleprotagonist since it was action and horror but it was actually a girl protagonist and that was a huge plus!

I couldn't stop checking for more in this series and this is the first time I hope they will make anime adaption for this one.

Note: It has "ecchi" genre but it is really light and not a reason to not read it.

Hope you enjoy this as well!
