144 issues [1996 - 2012]
1 - 144
How weird to see such a concise list. First time we've seen that in this series of posts. 144 issues, starting with #1, ending with #144 (for now, this is on-going, up to #157 now, I switched to digital for it after a long hiatus, but might still get the print issues eventually). That makes this the longest running book I had a complete set of.
This is the black and white Dark Horse published version of Stan Sakai's now two-decade old rabbit samurai comic book. Sakai's kept the book fresh through the years with a great variety of stories, lots of research on Japan informing the story and a large and varied supporting cast with interesting inter-relationships (I in particular like any interaction of Usagi with Gen, the bounty hunter and with his "nephew" Jotaro).
Lot's of great stuff, of course, including several long sagas including the two "Grasscutter" serials. A few shorter bits that I liked:
#23 - My Father's Sword (an epic of honour and redemption in 24 pages)
#46-47 - Showdown (a great 2-part Usagi/Gen story and two wraparound covers showing just about the whole cast in one scene)
#73 - The Pride of the Samurai (more tales of honour, plus a lot on the Usagi/Jotaro relationship)
