Eyeshield 21 is an American football anime/manga. It's fun. Has fantastical football moves like Prince of Tennis. Most of what I know about football comes from watching it XD

It depends on the situation as I don't give incest a blanket pass. I'm ok with some sibling incest. It has to have a lot of deep rooted emotion and the two should be on a relatively similar footing, as in no one sibling is forcing the relationship by holding power over the other or anything. It really depends. The internet has just mellowed me out about certain things and that's one of them. I don't always have the kneejerk reaction, except to parent or other adult/child incest. Then you get the outrage and the RAR RAR RAR!
