Normal high school student Midou Karuto one day out of curiosity came across the website "magatsuhi.com" but somehow could not access website. Thinking it was a prank website after all, Karuto turns off the Computer! But somehow... due to this 'prank' event, Karuto found out that the people around him—no matter if it's family, friends, or even strangers— occur all kinds of misfortunes, dying...missing...all kind of things starts to happen around him! And the time before these happen, the computer always turns 'on' by itself and the website starts to give him predictions about what's going to happen! And most importantly... Karuto has only a limited amount of time to stay "Alive" after being able to access the website! What can he do to save himself or the people around him!?? Or is he just going to wait and die until his 'time' runs out??
