The first notable one I can think of is watching the entire run of Elfen Lied in a single sitting, so 12 episodes. I’ve done that a number of times since though, most recently with the first season of Zombieland Saga.
One curious one was Magic Knight Rayearth. I watched most of the first season - 20 episodes - in a single day, but not so much because I was so hooked on the story. What it was was that if I didn’t catch it in time at the end of one episode, the next episode would start, so the OP would start, and that was it. There was no way I could turn off what is, IMO, the best OP ever, so I’d end up just letting it go, which led into the episode, and so on. I’m not sure how many total episodes I watched that way though.
I can only think of one instance when I’m certain I watched more than a single season/cour in a single sitting, and that was The Apothecary Diaries. I watched the first half or so of the first cour of the first season one day, and it was certainly good, but it hadn’t yet fully hooked me. But then when everything started coming together in the second half of that cour, I couldn’t stop, and I watched the rest of it plus the entire 12 episode second cour in one long binge. I’m pretty sure that started from about the time that Maomao went home to visit her father, which was episode 7, so that’s 18 episodes or about 7 hours.
Sort of thinking through my fingers here…
