The pessimistic and negative daughter of a concubine living in the ancient times thought – since life is so difficult, why should one invest serious effort in struggling to live?

The life of an ancient noble woman is often determined and controlled by her family. Moreover, one’s actions often implicate one’s entire family – thus, it is fairly common to see an unexpected calamity result in suffering borne by one’s whole family. Managing to live a good and successful life while retaining one’s dignity is simply too difficult to achieve.

Ah, living in the ancient times is simply too dangerous – we should all just sleep till we die.

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.

"One Sin can destroy a man..."

Azekiel, a young man, was forced to embrace his death simply for one small sin... the sin of Hunger.

It was only when he paid the price for his hunger with his life that he realized the cruelty of this world.

Watch Azekiel embrace the hunger that brought forth his demise as he walks on a path of total domination in the Tower of Sins, becoming the Seventh King of Sin: The King of unsatiable Gluttony!

The Tower of Sins... A majestic Tower that appeared in the world just as the world had lost all hopes.

Humanity was near extinction in the apocalypse brought forth by the appearance of Monsters in the once peaceful world. Their last hope... The mystical tower that had appeared out of nowhere became the shelter of humanity.

The humans that took shelter in the tower were many; amongst them were a few that were selected by the Tower itself. These Humans were known as the Lord of Sins, who received abilities from the tower itself.

As for what abilities, no one knew... All people knew was that the abilities they received were related to the biggest sin they committed in life. They were all given one task... Climb the tower and reach the top to receive incredible strength and freedom.

Only Lord of Sins and the people they selected were authorized to climb and go up, facing hardships. They were the gods of the Tower! The rest... They were left behind on Floor Zero. Amongst the humans left behind was Azekiel... A human who had never committed even a single sin in his life. Until...

A single sin can change a person's life. What happens when a good man commits a sin worthy of making him a Lord of Sin?

The legend of Sins is about to unfold that can threaten reality itself, bringing forth many unimaginable secrets of the world!
