Who said that these anime ends after one season? Many times, they have a cliff hanger ending because the producers were hoping to get a second season or they are a faithful adaptation of the first part of a manga that is only half finished.

Try finding me in one year when I've watched all of those shows

Thanks for the recommendations!

I wasn't kidding about the one year thing, I'm back! All of these shows were great. You weren't kidding about Bubblegum Crisis, I can't believe I put off watching it for so long, it was rad as hell. Noir was my favorite of these suggestions, literally the only thing that keeps it from being a 10/10 is the distracting lack of any blood. Bakumatsu was super interesting—it's cool seeing a show where half of the characters have Wikipedia pages. There's a certain kind of person who both has a deep interest in the Boshin War and likes historical fantasy, for whom Bakumatsu Kikansetsu Irohanihoheto is the best show ever made. I can't bring myself to say that Eat-Man was good, but the concept is interesting, and I absolutely adore Bolt Crank as a character. '98 definitely improved on '97, but I'm fond of both series

I haven't watched everything in your other comment yet, but I did watch Megalo Box, and it's one of my favorite shows now—makes it to almost every list of recommendations because of the differences between the first and second seasons. It's crazy how quickly it goes from shounen to seinen.
