@Kisshouin There is no way Gabimaru can end up with Sagiri. Feudal Japan took class status really seriously. The samurai class can't marry merchant class or peasant class, noble can only marry noble, and so on. Marrying outside of your class was actually considered a crime. Sagiri already sacrificed a lot in order to to be recognized as a sword tester and she prides herself as an Asaemon. Unlike Shion who was adopted to the clan, Sagiri is the daughter of the clan head. You want her to throw everything away including her father and bring shame to her family by becoming a fugitive with Gabimaru? Not possible.
Man such a well rounded and satisfying ending. A rare feat for manga these days. Now I'm extremely excited about the upcoming adaptation. It will surely help share this greatness to a greater audience.
