Oukoku e Tsuzuku Michi - Chapter 419: Battleship 〇〇

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.

A world where one’s life was decided by one’s talent called Gift.
The main character Erio Scarlet who was born in the house of influential noble family that had produced a lot of Holy Knights manifested a suspicious gift Incubus in the conferment ceremony. Furthermore the skill attached to that Gift was only one embarrassing skill called Peerless.

Erio was banished from the city because there was no way his indecent existence could be permitted in a family of Holy Knights but……somehow he went through an amazing growth when he dealt with his horniness though!?

In addition when his childhood friend who was bestowed with the Gift Sacred Knight chased after the main character because of her love for him reverse ra-……did it with him, a lot of powerful indecent skills showed up and on top of that they even got bound by Master-Servant contract……!?

This was the indecent heroic tale of the boy who was gifted with indecent Gift rising in the world while [getting along] with a lot of girls.

Instead of causing chaos with my knowledge of the original work, I assisted the protagonist.

I successfully completed the story and now planned to retire and live peacefully.

However, it seems the protagonist still needs my help.

An academy professor? That’s nothing much.

But why is the state of the academy so strange?”
