[Anime Crossover] Player's Otherworld Simulator

The world is a game, and he is its only [Player].

A young man appeared in Yokohama, trying to steal the Book to revive someone, just like the Guild. Strange accidents began happening one after another alongside his arrival.

After observing him, everyone realized he was closely connected to these incidents. But the person he wanted to revive seemed to be alive and well?

As a story-focused player and completionist, Player always unlocks the true ending when he gets a new game. But before he even started the main story, one side quest after another had already caught his attention.

So how did the main story's NPCs end up running into him while he was busy clearing side quests?

First Playthrough: Misaki Kazuha, Future Diary

It was obvious that he had lost his memories.

A hellish start.

How could someone with amnesia survive in dangerous Yokohama?

Misaki's advice was to stay in the safehouse and keep his head down.

[No matter what, I want to see him one more time.]

He wore a necklace containing what might have been someone's ashes. It was his only connection to that person.

The irony was that even this might be fake.

Second Playthrough: Fujiwara Chizuru, Control Devil

Fujiwara had an agreement with a runaway puppy: if the other ever used his power, he would have to come slinking home with his tail between his legs.

But the other had clearly gotten too used to roaming free, and treated their agreement like it was nothing.

Think of it as a trip.

He would bring the "lost" puppy home.

[I heard the runaway puppy calling for me in tears.]

Third Playthrough: Alexei, Imperial Arms: Murasame

Alyosha was a hero from the era of ability wars. After returning to his homeland to rest and recuperate, he suddenly received a request from Academy City:

Capture an ability user who could reverse time.

He knew this all too well, didn't he, Mikhail?

[Capturing criminals is the warden's duty. All I need to do is fight, fight, and keep on fighting!]

Fourth Playthrough: Mikhail, Zaphkiel

Misha liked watching people break down in the cracks between time.

The look on their faces as they tried to escape again and again, never tiring of the attempt.

That was, until he met an idealist, a man who longed for freedom.

He scoffed.

Humans couldn't escape time, just as Nikolai couldn't escape Mikhail.

[For the sake of absolute freedom, he provoked me, claiming he would escape my prison of time.]

Fifth Playthrough: Sakaki Harusora, Idaten

Harusora was an Idaten, an arbiter granted to the world by its laws.

Their task was to slay any god who might fall to darkness. In their experience, the moment a god developed human emotions was the first step toward corruption.

One day, they sensed the presence of a newly born Aragami. Though a god, the Aragami seemed even more human than humans themselves.

[What a pity. They can no longer exist in this world as gods.]

They raised their blade.

Xth Playthrough: Anna, "The Great Lie" and "Scriptwriting"

Anna, a liar whose very name was a lie.

[The world is a cage, abilities are a disease, humans are born and die without purpose, and everything will return to nothingness.]

↑ This is both an extra and a bonus playthrough.

This ability comes from Kumagawa of Medaka Box: a causal-law weapon.

Warnings!

1. Important characters die! The Bungo Stray Dogs story follows a completely alternate version of the Three Factions' Plan, with everyone reshuffled! Highlighting this for emphasis!

2. No identity reveals, ever. The protagonist will nip any risk of a reveal in the bud.

3. Player is chaotic evil, an extreme adherent to the path of ruthlessness, a self-interested player who treats everything like a game, and has empathy lower than the ground.

4. This is a full-dive game setting. It will never merge with reality.

5. There may be several accounts logging in, and the timeline is complicated.

6. The secret identities have their own romantic storylines, but Player himself will never develop feelings for fictional characters, so Player will not have a romance storyline.

There are countless good stories out there. If you don't like this one, you don't have to read it.
