Starting from the World of Detective Conan

He Chuan Makino, a man who walks between the cracks of the world. He calls himself a maintainer, but really he's just an overworked wage slave. As fragile little worlds grow, they inevitably stumble and invade one another. The Consciousness of the Science World: Why are all these people trying to take over my territory?! Stop making a racket! So, in order to maintain a peaceful, stable life, He Chuan set out on the diligent road of repairing the world's walls. But for some reason, innocent natives always get caught up in his efforts to save the world. He Chuan: Thanks for asking, but that's really not necessary. [The Never-Ending July] (Complete) Matsuda opened his eyes once again. An unfamiliar ceiling, a peeling blue bench, and the salty sea breeze washing over him. The red-haired man from his memories, who had been lying in an alley covered in blood, was now leaning peacefully against the seat, on the verge of falling asleep. Matsuda's gaze gradually sharpened. [Catch Me If You Can] (Complete) “Think of something, quick! Or else...” Everyone present held their breath. “Or else I won't talk to you ever again!” Watching the demon as if it had just been given a shot of adrenaline, He Chuan was deeply shaken. Akai pondered: So this kind of threat works too? [What Is the Most Precious Thing?] (Complete) “Go, Amuro! This is your moment!” He Chuan pointed ahead, burning with excitement. “Who's Amuro?!” Rei shouted. “I can drive a car, but I can't pilot a mecha!” [The Gem That Can Bring About Miracles] The Science World has no magic. That's the truth. Things you should know: 1. No System, no secret identities, no undercover agents, no true liquor, no transmigrators. The early story is an episodic adventure alongside the characters, interspersed with the main plot. 2. All the Police Academy friends survive, but this isn't a rescue story. The officers are saved by the butterfly effect. 3. There will be crossovers with some series that make you think, “Oh, this works too?” Essentially, this story is an excuse to catch up on shows. It's fine if you haven't seen them; you can read it as an alternate-universe story. 4. There are countless personal headcanons, and the timeline is a complete mess. If you find a plot hole, please feel free to ignore it. Additional note: 5. The story's setting is based on the material available before I started writing. Settings added after M25 are not included. Theme: Give someone a rose, and its fragrance stays on your hands.
