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.

All the people in the Tarot Empire know that the third young master of Le family is the most domineering, arrogant and beautiful Omega in the Empire. I don’t know how many alphas want him, but they dare not marry him. Now, under the order of the Imperial Marriage Center, this overlord flower will marry General Xu Yao, who is known as the ruthless Hell’s King of the Empire.

Tsk! It’s going to be fun!

So after X days of marriage…

Xu Yao: Butler, my wife hasn’t bullied you these days?

Butler: No, Madam is very kind, but he seems to think that you are a bit rude, he asked me to give you this paper.

It’s written:

~ Little Red Flower Agreement ~

Xu Yao: Pei!!! You think Lao Zi is a dog in heat and wants to do it with you?!

After a month…

Xu Yao: Hurry! I still need three more, whose family is bankrupt this time? I’ll send a charity money, hurry! ! !

Cheerful, kind and virtuous wife vs Black belly and pampering husband, 1vs1, HE
