Kohinatsu Asari was a college student.

Three times, in fact.

The first time, his information got accidentally deleted from his college and that college got bomb right afterward.

The second time his college accidentally got involved with a crazy witch who uses space-time magic to erase his whole school’s existence off their plane of existence and memories.

The third time, Kohinatsu finally graduated with a good grade and have already been accepted into a Top Rate IT company- only for his college students to get Blacklist because one of the Professors there accidentally unleash a virus into the world. The fourth time? There is no Fourth Time.

Kohinatsu’s trying to live a good and carefree life right in the middle of the world’s apocalyptic with his Systems. So, what Fourth Time?
