Conan I am Pikachu

A Pikachu accidentally traveled through time and space and came to the world of Detective Conan, which is six hundred years away from the time when the plot takes place.
During these six hundred years, let’s work hard to become a human being!
As for what will happen during this process, that is beyond his prediction.
Six hundred years later...
A little blond boy was sitting on the sofa, reading a newspaper in his hand.
"The Sherlock Holmes of the Heisei era, Kudo Shinichi..."
He put down the newspaper in his hand and stood up.
"Forget it, let's go to Teitan Elementary School to register first."
"Long time no see, Conan."

………………

Dozens of days later...
The blond boy looked at the brown-haired girl opposite him with confidence, patted his chest and said, "Don't worry, as long as I say a word, no one in this world will dare to touch you."
