Case 0: ???

[Welcome to the world of Fantasy, Detective]

"Huh?"

Looking up from where he sat, the male raised his head to see an old wood door, overgrown with some kind of bright green plant that rested on its right edge. Higher, but closer, a bright blue light glowed downwards towards the low male.

"Welcome to the world of Fantasy...Detective?"

The male had questioned as if he wasn't questioning the words that he read, but himself.

[Congratulations!]

[You have completed the transportation]

[Now start investigating, detective!]

"What the... What do you mean by investigate? And what is this about being a detective?"

The first confused, now frustrated male shouted.

[Whatever do you mean?]

Getting up to sit backward and yell at the blue light, the male shouted again.

"Hey! Answer the question!"

[You will only get answers if you investigate]

"And how am I supposed to investigate when the only thing I can get information out of isn't telling me anything!"

[...]

"..."

[You have a point]

"Exactly. Now tell me where the heck am I?"

[System is down]

[Please try again in the next 24 hours]

"Are you fucking kidding me."

[Well it seems like you've lost your memories]

[Poor you]

"And that's my cue to say fuck you."

[Such a dirty mouth]

"What an irritating asshole"

[How about we get started with the tutorial instead of arguing]

"Fine."

The male then adjusted himself to be standing up to face the blue screen which was at reading height for him.

He then looks to both sides to see basically nothing except for a grassland of almost nothing.

"Where the hell am I?"

[First off]

[You are currently in the world called, "Fantasy"]

"Isn't that the name of a genre?"

[So you do have your memories]

"Nope. Only basic knowledge without relation. Facts without any meaning."

[Alright]

[Since your past memories are wiped, you won't remember your name or your past]

[Your new name will be Chikao Katsunori]

"I don't even get to pick my name. This game sucks."

[Do you even remember playing any other 'games']

"..."

[Exactly]

[So in this world called Fantasy, there are abnormalities compared to the world that you come from called 'Earth']

"So I'm not from here?"

[Yes]

[You also were a Detective in your previous memories that are now gone]

[The door in front of you was the one that you used to get here in the first place]

"So I can open the door to go back to this so-called place named Earth?"

[Go ahead]

[Try it]

"It's locked isn't it?"

[...]

"...Fu-"

[So your end goal is to find out the mystery of this place called 'Fantasy']

[Afterwards, the door will open and you will be free to leave]

"Pretty simple."

[I had to simplify it so that your brain wouldn't overload with information]

[It wouldn't overload though, since it has nothing really in it]

"...What if I kill myself instead of solving this mystery?"

[Sorry not sorry]

[But you can't since as the system, you are not allowed to die]

[You just can't leave until you solve the case]

[But if you died...]

[You wouldn't be able to go back]

"Fine then."

[Alright!]

[Here is your first case then]
