This is my future. A world where a single woman, in a single moment, did more devestation than any bomb that has ever been dropped, or any weapon that has ever been fired. It is a world where every day we still feel the effects... just as the ripples cascade through the past and towards the future. It is a future with no hope...

My name is Kito Terad, Lieutenant in the Temporal Corps. Before that day, time travel was considered impossible... or at least, it took massive energy to do so. However, after that day, the barriers were weakened. One could travel to the day after the blast, but no further back. It was as if the explosion was destined to happen.

However, people try to exploit the ease of the travel now, and it is our task to guard over this solemn duty. For 3 years now, I have dedicated my life to stopping those that travel back in time to change the present. Today, however, I have been told that mission has changed.

Today, I start my journey to change the past.

First is to interview the only survivor from all those centuries ago...

The angelic being known as "Yami".
