Good anime that is pretty long?

trying to find to find some good long anime.Maybe at least 50 episodes. some anime that i seen that are pretty long are d gray man, bleach, naruto, one piece. zach bell, rouha kenshin( cant spell it), fairly tell, reborn and lots more. I love anime with powers, an i like them start out really weak or something an becomes really powerful as l8r in the series. I like when they have dark powers and their trying to control it like naruto with the 9 tails, an bleach with his hollow form. but it doesn't have to be like that. No mecca please. there can be romance in it, not all about it but they start to have feelings for each other. An I want a guy main character. I know its a long thing to ask but if you can please help me out!!!
