5/5 after the last 2 weeks I wasn't expecting much but this was actually pretty good, for a filler at least.
The animation was the best of the swordsmen fillers. The faces looked a little weird sometimes but the fighting was actually better than some of the canon episodes recently. Omoi's new moves were cool, now people can stop calling him fodder.
And what about Mangetsu? was he shown being sealed in the manga?
I don't have high hopes for this filler arc, the movies are always terrible and this is just a movie broken into 6 episodes.
