Detective Conan: I'm Aged Like a Fine Wine, Cellared for Ten Years

[System] [Invincible] [Red and Black Factions] [Dual Transmigration]

[The story begins when Shinichi Kudo is seven years old, ten years before Gin's blow disrupts the river of time.]

[The roller-coaster murder case happens at around 500,000 words.]

There are two transmigrators. If you don't like that, read no further.

In his previous life, Lin Ye transmigrated into the Naruto world, but with no System or talent, he died young.

This time, he transmigrates into the world of Detective Conan, ten years before the main story begins, and becomes Kato Ryoya. At last, in this life, he awakens his own System, which lets him buy items from various worlds.

.

With ten years to go before the main story, he has plenty of time to prepare. He'll start by building up his strength in the Black Organization, then quietly wait for the day he becomes invincible.

Shinichi Kudo (age seven): “You're only a little bit faster than me.”

Ten years later:

Conan Edogawa: “What? You knew that again? Again? Again?!”

Shuichi Akai: “A few years ago, you said we'd be colleagues. So that's what you meant.”

Toru Amuro: “I'll leave Hiromitsu in your hands.”

Hiromitsu Morofushi: “Arai Ryo is my new name?”

Rena Mizunashi: “That's not funny at all.”

Pisco: “That kid has incredible talent.”

Irish: “You still need a lot of practice, kid.”

Half a month later:

Irish: “...I lose.”

Gin: “Hmph. I could really use talent like that.”

Vodka: “My brother's right.”

Toichi Kuroba: “Wait, what else do you know?”

Yusaku Kudo: “He's an exceptional young man.”

Kogoro Mouri: “You're my kind of guy, kid.”

A year later, during the graduation exam, he discovers another transmigrator, and the other person finds him first.

Guess he'd gotten a little too carried away.
