Aren't Sakura and Tomoyo from CCS (Card Captor Sakura) cousins?
I'm 99% sure of it, but it's never been said in the manga, it's only childhood friend or classmate.

Cuz Sakura mom is Tomoyo's mom's sister, which makes her Sakuras Aunt.

And that makes Tomoyo Sakura's cousin.

Am i right or am i thinking too much?
