Primordial Heir: Nine Stars - Chapter 3: What was that?

Thousands of years ago, the First Expungement came. The world changed, and humanity was nearly wiped out. Thankfully, with the paracausal power of Angelicas, humans was able to push back the Ghost tide and rebuild their civilization.

Now, however, it was time for the Second.

Finn Thresher was just a normal university student at first. He, like the rest of the public world, had no idea what was coming for them — but sometimes, just because you don’t know, doesn’t mean you can’t be harmed.

His family… his sight… his purpose. All lost to the paranormal.

It was time to abandon his beliefs. To throw away his morals.

After all… if these creatures weren’t human anyway, there was no point in showing them humanity.

In the first battle of this war, the Ghosts won, nearly driving the human race to extinction. In the second, the humans fought back with the power of Angelicas and managed to secure a victory.

Now, the third and final round was approaching — and this time, it’s personal.

The happiest thing in the world is to be able to amend what you have done wrong. She who acted willfully because of a game, was reincarnated into a time when she still had her parents’ love.

Kyoukai Senjou no Horizon chronicles the story of a futuristic civilization returned to Earth after constant warfare hindered them from traveling beyond the post-Apocalyptic Earth. At this stage, a small archipelago called the Divine States were the only hospitable land on Earth. In order to regain the space-faring technology they had lost after many years of war, they decided to recreate history with a book called the Testament as a guide.

It is the year 1648 in the Testament Era. Toori Aoi, Chancellor and Student Council President of the only academy on the airborne city-ship Musashi, faces the ten-year anniversary of the death of his childhood friend Horizon Ariadust in an accident. As he prepares to celebrate the occasion by proposing to P-01s (an automaton who looks exactly like Horizon) he discovers that his suspicion about P-01s’ appearance actually has a basis in truth; P-01s is in fact Horizon Ariadust, reborn into a robotic body. In addition to this, Horizon’s emotions had been stripped away and are now stored in eight powerful weapons called the Mortal Sin Armaments; which are now in the possession of key people in various established countries in the Divine States.

To retrieve the emotions of Horizon Ariadust, Toori Aoi along with his friends and allies begins a crusade against different obstacles as key events in history are recreated in a futuristic manner.
