Yokohama Killer, Pixel Island Builder

Xia Wuyou saw a shooting star and earnestly made a wish: he wanted a sweet encounter with his favorite character.

Then he transmigrated and stumbled upon the scene of the former leader's murder.

He turned around and saw his favorite, Dazai Osamu.

Xia Wuyou: Is this... sweet?

Because he'd barged into the scene of the leader's death, he nearly blew his cover.

*

At the critical moment, Xia Wuyou was pulled into the System's space, where he learned in despair that the System had bound itself to the wrong person.

His [Romance Conquest System] had become the [Strongest Assassin System].

Fortunately, the System offered compensation: a little island-building game that could affect reality.

In the game, he could farm, fish, and clear land. As long as he completed the promotion missions to become the strongest assassin, he could also draw cards to summon island residents.

Xia Wuyou: But I still want my favorite.

System: Complete the missions and you can draw chibi versions of your favorite, including Leader Dazai, Moby Dick Dazai, and Academy Dazai. You can also give them cat ears, formalwear, kimono, and other outfits.

Xia Wuyou was hooked. He worked himself to the bone, playing day and night, and threw himself into collecting every character.

*

Several major events were happening in the real world at the same time.

First, powerful figures from every sphere were in a panic. Anyone who received a golden star-shaped gemstone would soon have their life claimed by an assassin codenamed "Xia." This assassin had never failed.

Second, an island shrouded in thick fog appeared in a certain stretch of sea. No one could enter, and all equipment and supernatural abilities failed there. People called it the Island of the Gods, a place beyond the laws of the world.

Third, a Mafia executive was kidnapped.

Later, people discovered that the person who had kidnapped the executive was Xia Wuyou, the strongest assassin, master of the Island of the Gods, and golden savior.

They announced that they were together.

Everyone in Yokohama: Wait, what?

#The male lead is a mischievous, chaotic fun-seeker, but bright and devoted to true love

#Main setting: Bungo Stray Dogs; island residents are characters from Katekyo Hitman Reborn; the background crisis is a Cthulhu invasion

-- Upcoming Novel: Is This Romance Game Legit? --

Fu Shuilian saw a shooting star. Amid the cheering, he thought indifferently: How boring. So what if the world ended?

Then some idiot teleported him into a book, where he became a gloomy, disillusioned wordsmith.

The System sheepishly told him that it had bound itself to the wrong person.

His [Evil God Development System] had become the [Romance Conquest System].

*

As a frail novelist, Fu Shuilian could barely survive in Yokohama. Just as he was wondering whether this was really a romance game, the System cheerfully unlocked a supernatural ability for him.

[Supernatural Ability: True Love Comes True]

As long as Fu Shuilian believed in love and made others believe in it, in theory, he could make anything he wished for come true.

System: Master, why aren't you smiling?

Fu Shuilian, who had committed countless evils, delighted in tormenting and twisting others, and absolutely did not believe in love: ...

*

Fu Shuilian worked things out and became a spy planted in the Mafia by the Special Division for Unusual Powers, then was sent by the Mafia to keep watch on the Armed Detective Agency.

At night, he would report to an organization called the Rats in the House of the Dead while writing his new novel.

Fu Shuilian was furious. Taking inspiration from the troublemaker Dazai Osamu and the bastard Demonic Genius he'd met, he wrote a heartwarming tale of healing.

Once he got into the swing of it, he went on to torment his good-hearted boss Nakahara Chuuya and his dark-circled superior Ango, writing a twisted, thrilling story.

Every book he published was invariably denounced as a dark, deranged act of social revenge. He snapped his pen, his ability went out of control, and everyone in Yokohama was pulled into his book to take part in a live-action role-play.

Fu Shuilian: ...

*

And so everyone in Yokohama learned that the city's three factions were jointly hunting down an author whose pen name was "Better Believe in Love Than Believe I'm a God," shortened to Love God.

Before Fu Shuilian's legendary identity as a spy was exposed, he found the Demonic Genius in his dorm room, reading his new novel: Hit by a car and left with amnesia, a substitute tears out his heart and goes mad with love. He runs, she chases, then an explosion sends them flying beyond the galaxy.

The Demonic Genius was the inspiration.

Demonic Genius: Good evening. I've been waiting for you for a long time.

Fu Shuilian: ...Do you believe that true love conquers all?

#A story about tormenting others; the protagonist's power has no upper limit, but no lower limit either

#Better believe in love than believe I'm a god. Wait, I really became a god

Theme: Open up! There's a hitman order!
