Blurb:
Asami’s best friend Chiharu has stopped coming to school and isn’t answering her phone. It seems she’s found something that’s a little more addictive than the school art club. But when Chiharu mysteriously commits suicide, all Asami finds in her room is a strange video game called Portus. With the help of two of her teachers, Asami hopes to solve the mystery behind her friend’s macabre death and the bizarre game itself. But is she prepared for the horrors of entering the twisted world of Portus, a game where, if you lose, there is no option to continue? A frightening vision of modern manga horror, Jun Abe’s Portus might put you off video games for the rest of your life.
