Howdy /rec/, this might be a bit of a complicated one.
I've been plowing through my backlog and I've come to the realization I'm actually reaching the end of it outside of things with higher episode counts like GTO and Lupin III. I'm not looking for shows that would be labeled as "hardcore" or "serious" at this exact moment, nor am I looking for anything really old. I'm looking for less serious shows that are either just enjoyable to watch or are funny with substance; think along the lines of Hyakko for the former and Hen-Zemi for the latter. I'd be willing to make a concession for a fun action show, too; I recently came off of a virgin watch of Jojo's Bizarre Adventure and Black Lagoon almost back to back (although the latter kind of drained my will for action shows) and I loved the entirety of the former a lot and the first half of the latter.
I am not looking for Toonami-level recs (i.e., FLCL), and I've already seen stuff like Abenobashi.
