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.

Ye Yang, the son of the Ye Family in Eight Desolate City, was once regarded as a genius. He could awaken his Dantian at the age of three and reach the third level of Qi Condensation at the age of five. But after a few years, He was seen as a person without talent because his cultivation was still stagnant at the age of 16. One day, He was framed and kept in a coma after he was rescued.

Ye Yang was originally an instructor in a special troop. He was 21 years old and sacrificed his life to protect an unknown broken sword which was found on Everest. When he woke up, he became Ye Yang from the Eight Desolate City, unexpectedly obtained the recognition of the broken sword and learned the mysterious cultivation method “God Slaughtering Technique”. He then embarked on a path of cultivating through slaughter.

When he was reborn, he swore, “I won’t let those who offended me off.” He wanted to reach the peak step by step, and also carried the mission to uncover the secret behind the Nine Heavens Mysterious Sword.
