otp: probably maeiso but karmagisa was the first ship I ever got into so it has significance to me, although I do like maeiso a little more.

notp: not really anything, most of the ships are fine. Anything incest or pedophilia is gross though, so anything like that I dislike.

brotp: rio and karma! their friendship is so fun and I really like both characters, I especially when in fanfic they matchmake or when in the actual thing they kept bothering Kaede about Nagisa.
