I had a strange dream.

An incomprehensible, abstract dream filled of images that appear and disappear.
Darkness, Chaos, Catastrophe. Butterflies that emit golden phosphorescence and of dying demons.

As the days pass by, those dreams become more concrete and more realistic. It's like a dream turning into a reality. When the day comes that this nightmare becomes real, I wonder what will happen to me? I wonder what will happen to this world.

However, it have nothing to do with me. The last week before summer vacation begins for me, Miura Tetsuji, an ordinary high school student.

This story is a work of fiction and has no relation to any real individual or any organization. But I do certainly exist in that fictional world. In this world filled with fiction.
