The previous second, Yuansaki Kirito was playing the part of the Forgers' perfectly ordinary older brother. The next, he transmigrated into the Detective Conan world.
He also got bound to a System that was passionate about tearing up scripts.
[Your mission is to make a complete mess of the original plot without shaking the foundations of the world.]
[Below are the secret identities you can use as disguises.]
Yuansaki Kirito took one look and went, "Oh! Aren't these the people from the Forger family? I get to pretend to be my own family?"
And so...
Teitan Elementary welcomed a new student: adorable on the outside, terrifyingly intelligent, and able to see through anyone's thoughts in an instant.
Conan: (adjusts glasses) Interesting.
Yuansaki Kirito: Think more slowly! I can't keep up with all this mind reading!
A new bottle of hard liquor appeared in the Black Organization. Other than his exceptional investigative skills and a perfect success rate, there was no information about him at all.
Gin: (disdainfully) Tch. A man of mystery.
Yuansaki Kirito: I'll remember that. I'm ready to dig up your little secrets at any time.
The Tokyo Metropolitan Police Department hired two new officers in quick succession. One investigated cases at a speed worthy of Sherlock Holmes, while the other was terrifyingly strong and could kick a bus flying.
Rei Furuya: (relieved) The future of the Public Security Bureau looks bright.
Yuansaki Kirito: No big deal. By the way, aren't you a bottle of booze?
And then there was Yuansaki Kirito himself, who could deliver a dimensional strike whenever he wanted.
Yuansaki Kirito: Huh? Didn't I mention it? I'm not human, you know.
When everyone in the Conan cast finally learned that they were all one big family...
"So it really is true that birds of a feather flock together?!"
Huh? Isn't it completely normal for there to be no ordinary people in the Forger family?
The protagonist is nonhuman, of the same species as Mikitaka Hazekura (a character from JoJo Part 4).
My own headcanons; inexperienced writing, lots of out-of-character moments. Please forgive me.
Theme: Unite the strength of the whole family to change the script.
