City of Sin - Book 9, Chapter 97

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.

After living as a famous Korean vlogger-slash-mukbanger, Neoma died a (shameful) death and regressed to her tragic first life— the life where she has to live as a hidden princess with a tyrannical father and a yandere twin brother.

She died at the hands of her psycho brother in her first life. But luckily, she charmed her “big brother” this time. Her father remains a sc*mbag, though.

But a blessing in disguise happened when her twin brother got “sick.” Because of that, she has to pretend as the “Crown Prince,” forcing her father to treat her well.

She thought she was finally on the road to becoming a lady of leisure.

But, despite her laziness, she still ends up completing royal duties that put her closer to the throne than her sick twin brother. The next thing she knew, they already prophesied her to be the first empress of their very patriarchal empire.

Now Neoma finds herself in the middle of the succession war she never wanted to be involved in!

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.

The King of Hell sentences you to death by midnight, but I can ensure that you live past morning.
