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.

Ding! The system activated the mission!

[Look at this sick old man in front of you. Let us pull out his oxygen tube and send him off. Let’s give him a peaceful mercy teehee~]

Shinomiya Aoba was stunned.

The old man mentioned by the dog system seemed to be a little strong…

Looking at the Gedo Mazo Pipe inserted in the back of ‘old age Madara’, he was silent and even wanted to laugh.

What do you mean his ‘oxygen tube’?

You want me to die?!

In addition… The super su*cide missions have been released:

[Personally experiencing the ultimate meaning of the Eight Inner Gates! —Take a hard kick of ‘Night Guy’ and shout out, ‘I would not call you the strongest!’] [Give Otsutsuki Kaguya a Thousand-Year Kill! —And record this beautiful moment!]

[Art is Explosion… and SpongeBob Squarepants! —-To accompany Deidara to self-destruct!]

[Inviting Terumi Mei to host the wedding —No less than a hundred words of congratulations!]

In addition, there were many other kinds of death-seeking missions waiting to be opened. And when the main character looked back many years later, everyone was holding back a sentence of “Damn it, he’s crazy!”

“This Ninja clearly didn’t look very strong, so why did he not die even after doing this?”

This was probably a poor child who had been dragged onto a path of death by a shitty system that’s set on seeking death.

Shi Jin once read a book. It was supposed to be about satisfying the desire for vengeance.

The main character, also named Shi Jin, was the sixth son of his harem-novel-protagonist-like father. All was well—while his father was alive. But after his death, Shi Jin’s five elder half-brothers tormented him, eventually leading to his death. The protagonist was reborn, determined to take revenge, and… the novel was discontinued.

That day, Shi Jin almost spat blood and dropped the book into a shredder. The next day, he died in a car accident. Somehow, when he came to, he had transmigrated into a teenager, a youth also called Shi Jin.

There was only one problem. His father had just died. His older brothers were about to torment him…

Shi Jin: Let’s eliminate my brothers’ hatred, my goal is to keep my life!
