Meet Teragane Haruto, your typical high school student without any aspirations or wishes of his own.

An eyed pillar sprung out from the earth, with the intent of killing any human that came into its gaze like it was a mindless murderer. Why is this happening? And what could have brought this amount of hatred unto human kind?
