This is the best graphic novel I've read in several years and I can't wait to pick up the next in the series. It's a feudal Japan-inspired setting with the action taking place among an archipelago on the edge of the empire. (The back of the book has a few pages on the lore of the setting and various factions, but none of that really matters in this first book.) The titular hero is a ronin, accompanied by a consistently tipsy water priest, and a masked oversize warrior with an unusual ability to absorb damage.
The trio arrive at a small island where a prostitute is abducted by pirates. Her young brother hires them to rescue her, and so the adventure begins. This takes them to a notorious port casino, and then on to a mysterious distant island where a lord rules from a floating castle. The story mixes action, magic, and sneaking around perfectly, reminding me of the best kind of D&D adventures. Like most translations of European BD, this combines two shorter books to provide the complete story.
But what makes the book special is the artwork -- absolutely gorgeous in creating a sense of place, with incredible attention to detail in each panel. Where most books treat backgrounds as empty spaces that the reader's eyes will gloss over, this has stunning amounts of interest, with servants, decor, and texture lurking at every edge. When showing a balcony, instead of leaving it at a standard series of wooden joinery, this has intricate coils of rope at every juncture, creating a real sense of place. Can't wait to read the next one!
