We Agreed to Save the World, So Why Are You with the Villain? Doomsday Fourth Catastrophe / Detective Conan

Ueno Shin transmigrated into Detective Conan and was bound to a System.

The System determined that a serious bug had occurred in this area: the death toll was far too high, time was distorted, and what should have been twenty years had passed in less than one. The problem also seemed likely to continue.

The cause of all this was the protagonist of this world, Shinichi Kudo.

Ueno Shin's mission was to restore the world to normal.

Ueno Shin: So, should I take care of Shinichi Kudo?

System: Of course not! He's the protagonist. This world exists because of him. We're here to save the world, not destroy it!

System: We need to solve the problem another way! For example... it all started when the Black Organization gave Shinichi Kudo poison and turned him into an elementary school student. So all we have to do is deal with the Black Organization, then find a way to turn Conan back into an adult, and the world will return to normal!

Ueno Shin: But I'd rather destroy the world?

System: ...

System: All right, I know this mission is tough, so I can give you some help. For instance, I can disguise this world as a game and summon players to help you!

The players entered the game, thrilled and ready to show what they could do and save the world. Then...

Ueno Shin stood before them, his expression calm. "I'm your master. From now on, you'll all do as I say."

The players: "...?"

Why did this game sound so shady?

At first, the players thought they'd entered an adult game. Later, they discovered it really was an adult game.
