On a quiet summer day Tokyo was rocked by a massive terrorist bombing. Nobody knows who did it but a strange video uploaded to the internet was trending online before the attack and provides the only clue. The grim truth is that the culprits were two high school boys who go under the codenames Nine (real name Arata Kokonoe) and Twelve (real name Touji Hisami), both of whom have an agenda against the state that is fuelled by a tragic background. They become known as “Sphinx” and start to play a deadly game with a nation that was once complacent but now lives in terror of them… One girl, mercilessly bullied by classmates, finds herself becoming close to them as she finds resonance in terror.
