Good, long action romance anime?

I've seen Rosario + Plus, Kanon, Buso Renkin, Watching Shakugan No Shana and Kampfer, Seen Clannad, Kanokon, Onegai teacher and Ichiban Dai Mao. I love anime like Kampfer, Ichiban Dai Mao and Shakugan No Shana. Can someone help, I want one that's longer than 24/26 episodes. I hate ending up seeing it all in one day (I don't really have a life) and I can't find any T_T Please help
