>>115267919We just finished a massive annual share thread of the entire series start to finish about a month ago
https://desuarchive.org/co/thread/113704829/Most of the series are one-shots and it's fairly easy to jump in wherever and not be too lost. That said a lot of the arcs are major highlights. Dragon Bellow Conspiracy, Grasscutter 1/2, A Town Called Hell, Treasure of the Mother of Mountains, Taiko, etc etc etc
There's a LOT of misery porn especially during a particular stretch about midway through the run, but generally if they like TMNT-esque stuff then I'd think Usagi is a safe bet.
>>115268058Ran is fucking incredible though it's not at all a samurai movie in the conventional sense. Sanjuro is great, there's a duel in it that is pretty much the origin of the massive-overexaggerated-blood-spurt cliche you see all the time in anime
