This is now the official page of Canonism with all the relevant tenants.
Canon is god. All those who are good worship Canon and must follow it to the letter.
Headcanon[]
This is headcanon. Headcanon is the devil. Do not follow headcanon.
Ship[]
Ships are weak. They will always be destroyed by canon. Even if it's made of steel or diamonds and powered by Steam, your favorite ship is shit.
Z[]
This is Z. Z is Canon.
Detective Canon[]
Like 5% of the series that is known as Detective Conan. The rest is filler.
Otherwise, how has literally nobody aged?
