This has been living in my head rent free since I saw it two days ago and now I'm like Cousin AU, where Toichi still died but whatever happened between the brothers didn't happen (idk if anything actually happened, I can't watch the movie until it's off theaters TvT) so the cousins knew each other and are pretty close. Dunno why Yusaku didn't look into his death (maybe decided it'd be better for it to go unsolved/lied about, which has def happened in canon before and Shinichi did it too in the whole plastic surgery case) But young!Shinichi is like no!! i swear something is up and I will prove it + I will protect my friend/cousin >:( and they work together from the start Introducing the progressive shounen-action-ification of the DetCo series xDD first we get explosions, now we get power creeping!! Don't know if it's been confirmed or denied canonically if Snake is part of the B.O. but if he is that would honestly be hilarious. Part 1: the entirety of Magic Kaito 1412, including the multitude of other thieves. So. Many. Thieves. (not that I'm complaining) Part 2: You've defeated the theives, now you're up against Snake's organization!! Mystery focus potential, but also explosion potential Part 3: You've defeated Snake's organization, but that was merely an introduction into the Black Organization (Shinichi may or may not get shrunk, I haven't decided). Insert ominous foreshadowing and a single clue that spirals Part 4: Some level of B.O. shenanigans, and then a strange woman becomes Ran's English teacher! (Jodie) Part however-long-this-series-will-go-on: the entire world gets involved with the pair at the center of it and somehow the B.O. still hasn't been handled. Vermouth dynamics with Kaito and Shinichi would be SO much fun (would Kaito also get a nickname or would he be brushed off LOL) What's Yusaku doing in all this???? Avoiding his editors, probably. Bonus: The Kudo mansion with a secret room AND an aviary. Just make it Hogwarts at some point. Bonus 2: Agasa and Jii interactions!!! Which I swear has been hinted at in canon that Agasa is the friend and has (unknowingly) helped with KID gadgets. Bonus 3: Agasa actively working with KID on gadgetry would be off. the. rails. Chaos squared.
Okay okay I know the shippers are grieving KaiShin right now BUT
May I offer you platonic/familial KaiShin?
Just think. They may not know it in canon yet, but Shinichi is technically Kaito's only relative who hasn't fucked off and abandoned him
Like at this point Shinichi/Conan probably gives more shits about Kaito/KID than both of Kaito's parents
Imagine the fanfic potential
Them finding out they're related
Kaito half glad and half weirded out that he has another relative who's actually here
Shinichi being baffled at Kaito's fucked family situation
Maybe even Shinichi going off on his dad for seemingly letting Toichi's son believe he's dead
Maybe even Kaito going off on his dad for, well, everything at this point
The drama
Imagine
